No I/O modules are required. The ProfiBus PA cable is dropped and connected to each device. Passive junction blocks can be used to make it easy to connect several blocks locally, but these are not I/O modules since they are passive and not active (no configuration or memory).
Profibus PA is used to communicate directly with the device (transmitter, sensor, etc.). The data resides in the device and is transferred to/from the PLC without having to go through a remote I/O subsystem (interface card, analog and digital I/O cards, etc.). This simplifies the cabling and structure for communicating with the field devices.

Yes. I can use a variety of devices to connect sensors using Profibus near the location of the sensors, and then connect one cable back to the PLC rack. This saves space, cable, and wiring costs.
@@realpars So you mean in such setup, the Input/Output PLC Modules(Cards) are not present in the PLC Rack in Control Room but are present somewhere in a JB in the field near the concerned sensors, right? Please confirm/clear my ambiguity.

The sensor needs to have the electronics to be able to interface to ProfibusPA. Modern sensors/transmitters are able to be specified with a number of different interface cards installed. If your plant uses ProfibusPA, then the sensors/transmitters need to be purchased with ProfibusPA interface cards. Your sensor electronics need to match your instrument bus type. ProfibusPA and ProfibusDP have different data packet structures and baud rates for communication. TIA Portal can be used to configure many aspects of each protocol, so although the front-end may look similar, the packets used in communication are not.
I would need to know the specific model o the encoder to say exactly, but a blinking red with steady green LED usually indiates the encoder is ready for operation but not activated by the master (e.g. incorrect address configured).

Hello I have one question when profibus PA was used input modules of the PLC were removed. So where exactly are they now? Are they in control room near the PLC or in the segment coupler? Or near the sensors?
ProfibusPA is a bus protocol that gathers data from the nodes (sensors) attached to it. There only needs to be a Profibus-DP/PA linking device to join the PLKC to the ProfibusPA segment. There can be many Profibus PA segments attached to one PLC. Each linking device provides the same function as the I/O rack and cards in a traditional installation. The thing I appreciate is that bus networks such as Profibus PA eliminate a lot of I/O panels, saving cost and space.

Typically a transmitter or other interface electronics is used to connect the sensor/device to the PA bus. You must have a Profibus-PA enabled connection/interface to place a sensor on the Profibus PA segment.
Thanks for the good video, however some comments: When you explain in profibus DP the sensors are connected to the I/O, you should clarify what kind of connection, e.g analog 4-20ma?. When using profibus PA, same type of sensors can be used?
4-20ma transmitters develop an analog signal by varying the current along the wire connected to the analog input card. ProfibusPA is completely different. ProfibusPA and 4-20ma are not compatible. For ProfiBus PA, you will need a different transmitter, cabling, power supply and communication card. ProfiBusPA is a digital communication protocol, not analog like 4-20ma. Each transmitter is considered a node and is configured with software provided by the host controller. ProfibusPA devices can communicate much more data than the single PV variable of analog transmitters, incuding PV, totalizer values, sensor health, and configuration parameters (like range and alarm setpoints),
Is PROFIBUS and foundation fieldbus network follow same strategy to transfer data from field devices ? What’s the basic difference between them ? By the way kudos to entire team. Never watched a video which is as easy as this to learn about automation and plant control.
With Profibus PA, you are communicating directly with sensors, valves, etc., and do not require separate I/O cards. Each device has the capability to provide many values for configuration, monitoring, and control.
@@realpars but how does it differentiate between the sensors on a PA bus? Does the sensors have some sort of ID? should we use some different kind of sensors on a PA bus?
Profibus requires an external 24VDC power supply and a Profibus DP master, like a CP343 card in a PCS7 system. The data transmission is controlled by the master at a configurable baud rate. A ProfiBus system uses a bus master to poll slave devices distributed in multi-drop fashion on an RS485 serial bus. Data streams are parsed by packets according to the GSD file that defines the data string for a particular device. A packet can have up to 244 bytes.
Thanks for awesome video...please make one video on PDM ,how we can configure sensors parameters on simatic manager or already have plz share link.. thanks
Thanks for your comment! That would make for a great topic suggestion, I will happily forward this to our course developers. Thanks for sharing and happy learning!
Yes and no. Each protocol has a specific way that it interacts with the device they are connected to. ProfibusPA is used mainly for motors, drives, scales, etc., that regularly receive commands (start, stop, tare. etc.). These devices may have setpoints or feedback parameters that are analog in nature (integer values, etc). ProfibusPA is constructed around process transmitter data, with many floating-point values and slower update times (250msec) than typically is used for Profubus DP (50msec updates). The cards used in DP and PA devices are quite different and are constructed to handle the specific interfaces.
I a project I have used profibus, Which connected graviometric controller to Profibus remote module via profibus cable & profibus remote module was connected to PLC. I am eager to know what type of Profibus connection that was ? Profibus DP or profibus PA?
Hello, @biplabmukherjee1480. This is a good question. However, as we stated in our video, it is connected to Profibus. Look at the part numbers of the connection devices from your PLC to your remote devices. You have the RS-485 coming from your PLC connection device or PLC direct, and if it is going to your devices directly with no Segment Coupler, as we show, then it is DP. If you have an RS-485 to a Segment Coupler to your devices, then it is DP to PA Profibus. Remember, they are both Profibus. However, there are two types of electronic communication devices.
The MPI/Profibus coupler is usually located in the same place as the master communication cards, which is typically in the control panel with the CPU or network components. This location is usually in an environmentally-controlled operating room or equipment area.
Profibus PA has a data transmission rate of 31.25 kbit/s. the speed of a Profibus DP network is selectable at the master to run at speeds between 9.6 kbit/s and 12 Mbit/s. A particular speed should be chosen for a network to give enough time for communication with all the devices present in the network. I find that Profibus DP is most stable at speeds of 500 kbit/s and 1.5 Mbit/s.
2:25 is it that far cheaper? Because, when you placed the I/O module close to sensors, you'll probably need to place it in an electrical board. That electrical board will need a power supply. Incoming from 230VAC, you'll need a 24VDC to supplies the I/O module, breaker, etc. Or how is it done? So i just wondering is it that far cheaper?
Hi there, Thanks for your question! Yes, it is cheaper. The cost of a local control panel next to the sensors is far cheaper than running the wires, conduit, and other electromechanical components. And the real cost is in the labor to do all this work. In addition, when it comes to troubleshooting the sensors, it’s a major advantage to have the I/O boards connected to the sensors where you can see and measure the voltage coming from the sensors to the I/O boards. Imagine having the PLC I/O boards 25 ft or more away from the sensor, and you are trying to troubleshoot a sensor or I/O, and you can’t see the indicator LED signal on the board. Happy learning from RealPars!
When we removed PROFIBUS-dp and put a unified cable PROFIBUS-pA, how does the PLC know from which sensor this signal is, because all the signals are in one cable?
Profibus PA communicates much the same way as Profibus DP -- via telegrams (data packets). In the header of each data packet is the node number from which the data came. The node numbers are unique on a Profibus PA segment for each device (sensor).
But Profibus PA is not connecting directly. Letsay I have one proximty sensor input signal. i want to connect to specific input of PLC. How can I? because video showed there is no I/O module. only thing is have BUS.
ProfiBus PA is typically used for analog devices. The function that a PLC I/O card would play for one input channel is "built into" the ProfiBus PA device, where the device address, as well as all of the required configuration parameters, are resident in the sensor electronics. And yes, a ProfiBus PA sensor does "attach" directly to the I/O bus network and is polled by the ProfiBus PA master card/node. Individual proximity sensors are often hardwired to a PLC card or are interfaced to the PLC via a ProfiBus DP node, which can be a multi-point I/O block.
Except cabling efficiency what other benefit profibus PA provides over profibus DP? At what number of devices we should shift from profibus DP to profibus PA. Next, how much is the cost difference between the two setup for a given number of field devices?
Profibus PA allows for a larger array of data to be queried and set in the device as compared to Profibus DP. Profibus PA is used to connect transmitters, actuators, and other analog devices to the network. There is a way to install Profibus PA in an intrinsically safe manner, whereas there is not with Profibus DP. Profibus DP is a faster protocol and is well suited for digital devices like motors.
Thank you for the simple explanation.. I am wondering if the Profibus PA is an replacement of HART protocol and what is the difference between these two protocols.
Yes, HART and ProfibusPA are very similar in the type of data that is provided between the sensor and control system. HART is somewhat simpler, since most analog sensor now come standard with HART and most analog I/O cards provide a HART interface. HART can be used regardless of the communication protocol used by the Remote I/O subsystem. ProfibusPA must use a linking device to transmit data to/from the sensors as well as 24VDC power. HART uses loop power from the control system analog cards.
I noticed Profibus is being used on the Honeywell Intelligrated Intelisort. Can someone tell me what type of Profibus is being used for this system? I am the new guy on the block, and I am interested in training on Profibus. Any advice on top training providers specific to Profibus.
The Honeywell Intelligrated Intellisort system uses Profibus DP. Realpars has many videos featuring Profibus use in Siemens PLC systems. There are a number of TH-cam videos (like this one) that can give you basic training in Profibus. The Profibus International organization has courses to become certified in troubleshooting or network design if you need more formal training or certification.
Thanks for your topic suggestion, Muhammad! Great suggestion. I will happily go ahead and pass this on to our course developers as a possible topic suggestion.
Great question! The process varies depending on the specific programming software you're using. Take, for instance, Omron, Allen Bradley, Siemens, and others. Explaining the intricacies within my response would be quite an information overload. However, I can certainly share that when you're working on programming your network, the software handles the addressing details. To delve deeper, I'd recommend checking out this informative resource on Siemens. It provides an excellent explanation and more in-depth information that might just answer your queries.

Buenas tardes, gr por el vídeo, pero este me generó algunas dudas: Que voltajes manejan y que tipo y cantidad de información envía cada uno, los cables son iguales o que diferencia tienen?
Gracias por su pregunta. Primero los cables son diferentes. Debes utilizar un convertidor de DP a PA como mencionamos. Utiliza un cable DP antes de su convertidor y luego, dependiendo de sus dispositivos, debe usar el cable recomendado como se menciona en las especificaciones del convertidor y sus dispositivos, que debe ser un cable común. Puede agregar fibra óptica según sea necesario para sus dispositivos y convertidores adicionales para la fibra óptica. Los vendedores pueden proporcionarle información.

Hi Mark, Thanks for your comment! Unfortunately, we no longer support the RealPars App. You can continue watching our video courses on our learning platform.
Can you please explain that how sensors are connected to profibus PA bus means sensor have 2 power cable and no nc output cables how they are connected to profibus PA bus
it's easy to connect a siemens plc or a scalance with profibus, but what about a sensor? how does a sensor connect to profibus? for example a thermocouple probe?
A sensor needs to have a Profibus interface built into the sensor. Typically, for these sensors, this will be Profibus PA. Profibus is a 2-wire system that has special connectors for use with Profibus PA sensors. Usually, an M12 connector is used. A thermocouple probe would not connect directly to Profibus. It would need to be connected to an RTD card in the PLC system or be connected to a transmitter that has a Profibus PA interface.

Profibus DP has had a few versions over the years: V0, V1, and V2. All versions are backward compatible, so as long as the master (the PLC) is at or above the revision of the connected drive, communication should work. Many devices have a selectable Profibus DP version selection that will allow the device to work with CPU's at a previous revision level.
Hi Nasir, Thanks for your comment! This would make for a great new video course. I will happily pass this on to our course developers as a topic suggestion. Thanks for sharing!
Yes, a segment coupler allows a Profibus PA segment to be connected to a Profibus DP segment, which is required to be accessed by the PLC's DP port. Profibus PA is designed to connect directly to the process sensors without the need for a remote I/O rack or interface.
Are the same type of sensors / transmitters used for profibus DP or PA? The PA seems very similar to foundation fieldbus setup while the DP follows the 4 - 20mA convention.
ProfibusDP, ProfibusPA, and FFB are all based on the same physical layer (RS-485). However, that is where the similarity ends. Sensors made for each of these three protocols are NOT compatible with networks of the other two. Sensors are typically provided with one of the following interfaces: 4-20ma/HART, ProfibusPA, or FFB. So yes, ProfibusPA and FFB are very similar, but not interchangeable. Devices such as scales, motor controllers, VFD's, and some analyzers are typically provided with one of the following interfaces: 24VDC/4-20ma, ProfibusPA, ASi, or DeviceNet.
Profibus DP is a high-speed (up to 12Mb/sec) RS-485 serial network that can be used to pass data from devices such as weigh scales, remote I/O racks, VFD's, and other devices that typically have large embedded data tables. Up to 128 nodes can be placed on one Profibus DP segment. The bus is an active powered bus that requires termination resistors at each end of the segment. The segment is connected to each node in a multi-drop configuration. Profibus PA is used to interface process sensors to the control system. Profibus PA operates at 31.25Kbit/sec, but the amount of data shared with each sensor is relatively small, and data update rates are typical for a process sensor (about every 0.25 seconds). The physical of Profibus PA is Manchester-coded bus powered (MBP). At the communication protocol level, Profibus PA and Profibus DP are identical.
Thanks for your comment, Mohammed! Great question, this would make for a great topic suggestion. I will go ahead and pass this on to our course developers. Happy learning!
Great question! Answer: No. The limit per segment of Profibus PA is 32 nodes. For Profibus DP, it is 125 nodes per segment. This is not a problem for addressing, as the Profibus master or link coupler is able to handle up to the maximum number of nodes and the maximum memory per node of 244 bytes. If you do the math, for Profibus DP this is only ~31k of data and for Profibus DP this is only ~8k of data.
For Profibus DP, the position of I/O cards in remote (and local) racks is defined by the hardware configuration which is downloaded to the CPU. If you remove a card, the hardware configuration will need to be updated. For Profibus PA, each sensor has a unique node address. If you remove a sensor, that node will no longer communicate, but that will not affect any other node. Independent power supplies are used to power Profibus segments, separate from PLC/CPU power.
Hi Alexander, Thanks for your comment! We currently only provide our course videos in English, you are always able to turn on the English subtitles as that might make it a bit easier for you. Hope this helps! If I can be of any further assistance, please let me know - I’m more than happy to help! Happy learning!
The best way to tell is to inspect the hardware configuration for the system you are using. Other ways to tell: Profibus DP cables usually have purple jackets and Profibus PA usually has orange jackets. This is not a foolproof method, but if cables meet the standard, this is an easy way to visually inspect for DP or PA. Another good way is to see what devices are on the Profibus network. If you see VFDs, drives, weigh scales, etc., connected by 9-pin connectors, it is Profibus DP Often, the interface card they are plugged into indicates Profibus DP on the hardware port. Profibus PA networks typically use passive connection blocks, usually with M12 connectors, and are used for transmitters, analyzers, and flow meters, etc.
Thank you for your question. Yes, it is. PA is a bit slower and made for another type of application compared to DP, but they use the same protocol. Here is a link for your learning. us.profinet.com/what-is-the-difference-between-profibus-dp-and-pa/ Happy learning!

Hi Kholio, Thanks for your comment! This would make for some create new video courses. I will happily pass this on to our course developers for possible future video courses. Thanks for sharing and happy learning!
@RealPars but how does it differentiate between the sensors on a PA bus? Does the sensors have some sort of ID? should we use some different kind of sensors on a PA bus? Thanks
Each node on a ProfiBus-PA network has a node address (0 - 31). This can be set by DIP switches on the device or via a configuration interface at the device. Only devices with a ProfiBus PA interface can be used in a ProfiBus PA network. If you have a 4-20ma transmitter and want to use it on ProfiBus PA, you will need to change out the electronics on the device. It is not as easy as upgrading from 4-20ma to HART, but ProfiBus PA will give you access to a whole lot more sensor-level data, configuration, and diagnostics than a HART interface can provide.
You can make that analogy. For Remote I/O racks that contain I/O cards and are connected to the main CPU through the use of a Profibus communication interface module, the similar system in the Allen-Bradley system would be Remote I/O racks that contain I/O cards and are connected to the main CPU through Ethernet/IP. VFD's can be connected directly to the Profibus DP network (with the proper interface in the VFD) jut like a VFD can be connected to Ethernet/IP (with the proper intreface card).
Both are similar but distinct protocols. Both use single twisted-pair, shielded cabling and require termination resistance. Both are based on the same physical layer, so the previous similarities are expected. There are many differences. FF is publisher/subscriber based, and can be directly connected to a card in the PLC or DCS via FF H1; PA is master/slave based and requires a gateway or link coupler to be connected to the PLC or DCS (usually linked with Profibus DP). For FF, I/O is mapped via embedded standard function blocks, whereas PA uses customized GSD files for mapping of device models. Typically, 8-12 devices are able to be connected to a segment. For PA, up to 22 devices can be connected to a single segment. I have used both extensively, and both perform well in the industrial environment. The key is planning and understanding of the limitations of each protocol (total power available, connectors and terminators, data update rates. etc.).

Thanks for the good video, however some comments: When you explain in profibus DP the sensors are connected to the I/O, you should clarify what kind of connection, e.g analog 4-20ma?. When using profibus PA, same type of sensors can be used?
4-20ma transmitters develop an analog signal by varying the current along the wire connected to the analog input card. ProfibusPA is completely different. ProfibusPA and 4-20ma are not compatible. For ProfiBus PA, you will need a different transmitter, cabling, power supply and communication card. ProfiBusPA is a digital communication protocol, not analog like 4-20ma. Each transmitter is considered a node and is configured with software provided by the host controller. ProfibusPA devices can communicate much more data than the single PV variable of analog transmitters, incuding PV, totalizer values, sensor health, and configuration parameters (like range and alarm setpoints),
Please upload a detailed video about profibus
Is PROFIBUS and foundation fieldbus network follow same strategy to transfer data from field devices ? What’s the basic difference between them ? By the way kudos to entire team. Never watched a video which is as easy as this to learn about automation and plant control.
Thanks.its the easiest explanation I've ever watched
Amazing to hear that! Thanks for sharing.
So 1 cable to the DP part and 1 cable back? Back and forth on different cables, right?
Thanks for the explanation , it was easy to understand !! . Do we still require IO modules with the PLC in case of Profibus PA
With Profibus PA, you are communicating directly with sensors, valves, etc., and do not require separate I/O cards. Each device has the capability to provide many values for configuration, monitoring, and control.
@@realpars but how does it differentiate between the sensors on a PA bus? Does the sensors have some sort of ID? should we use some different kind of sensors on a PA bus?
I have one question how profibus DP transmit data?
Profibus requires an external 24VDC power supply and a Profibus DP master, like a CP343 card in a PCS7 system. The data transmission is controlled by the master at a configurable baud rate. A ProfiBus system uses a bus master to poll slave devices distributed in
multi-drop fashion on an RS485 serial bus. Data streams are parsed by packets according to the GSD file that defines the data string for a particular device. A packet can have up to 244 bytes.

Hello and thank you that was so helpful
my question: can both (rofibus dp and profibus PA) do the analogic sognal process ?
Yes and no. Each protocol has a specific way that it interacts with the device they are connected to. ProfibusPA is used mainly for motors, drives, scales, etc., that regularly receive commands (start, stop, tare. etc.). These devices may have setpoints or feedback parameters that are analog in nature (integer values, etc). ProfibusPA is constructed around process transmitter data, with many floating-point values and slower update times (250msec) than typically is used for Profubus DP (50msec updates). The cards used in DP and PA devices are quite different and are constructed to handle the specific interfaces.
I'm preparing for my ISA CAP Associate exam and this series of introduction videos are incredibly helpful!
Glad it was helpful! Best of luck with your exam!
I a project I have used profibus, Which connected graviometric controller to Profibus remote module via profibus cable & profibus remote module was connected to PLC. I am eager to know what type of Profibus connection that was ? Profibus DP or profibus PA?
Hello, @biplabmukherjee1480. This is a good question. However, as we stated in our video, it is connected to Profibus. Look at the part numbers of the connection devices from your PLC to your remote devices. You have the RS-485 coming from your PLC connection device or PLC direct, and if it is going to your devices directly with no Segment Coupler, as we show, then it is DP. If you have an RS-485 to a Segment Coupler to your devices, then it is DP to PA Profibus. Remember, they are both Profibus. However, there are two types of electronic communication devices.
Nice video, but the biggest benefit of Profibus PA is that i can be used in Ex environments.

coupler is in control room or factory floor?
The MPI/Profibus coupler is usually located in the same place as the master communication cards, which is typically in the control panel with the CPU or network components. This location is usually in an environmentally-controlled operating room or equipment area.
@@realpars Is placing a coupler in a factory floor a mistake? Is it acceptable?
Thank you for the professional video.
Is there a difference between profibus PA and profinet?
Can you tell about the what's the speed of perfect DP and Pa
Profibus PA has a data transmission rate of 31.25 kbit/s. the speed of a Profibus DP network is selectable at the master to run at speeds between 9.6 kbit/s and 12 Mbit/s. A particular speed should be chosen for a network to give enough time for communication with all the devices present in the network. I find that Profibus DP is most stable at speeds of 500 kbit/s and 1.5 Mbit/s.

Thank you, Kelton!
Thanks for this video, unfortunately your application is not exist on Appstore
2:25 is it that far cheaper? Because, when you placed the I/O module close to sensors, you'll probably need to place it in an electrical board. That electrical board will need a power supply. Incoming from 230VAC, you'll need a 24VDC to supplies the I/O module, breaker, etc.
Or how is it done?
So i just wondering is it that far cheaper?
Hi there,
Thanks for your question!
Yes, it is cheaper. The cost of a local control panel next to the sensors is far cheaper than running the wires, conduit, and other electromechanical components. And the real cost is in the labor to do all this work. In addition, when it comes to troubleshooting the sensors, it’s a major advantage to have the I/O boards connected to the sensors where you can see and measure the voltage coming from the sensors to the I/O boards. Imagine having the PLC I/O boards 25 ft or more away from the sensor, and you are trying to troubleshoot a sensor or I/O, and you can’t see the indicator LED signal on the board.
Happy learning from RealPars!

When we removed PROFIBUS-dp and put a unified cable PROFIBUS-pA, how does the PLC know from which sensor this signal is, because all the signals are in one cable?
Profibus PA communicates much the same way as Profibus DP -- via telegrams (data packets). In the header of each data packet is the node number from which the data came. The node numbers are unique on a Profibus PA segment for each device (sensor).
But Profibus PA is not connecting directly. Letsay I have one proximty sensor input signal. i want to connect to specific input of PLC. How can I? because video showed there is no I/O module. only thing is have BUS.
ProfiBus PA is typically used for analog devices. The function that a PLC I/O card would play for one input channel is "built into" the ProfiBus PA device, where the device address, as well as all of the required configuration parameters, are resident in the sensor electronics. And yes, a ProfiBus PA sensor does "attach" directly to the I/O bus network and is polled by the ProfiBus PA master card/node. Individual proximity sensors are often hardwired to a PLC card or are interfaced to the PLC via a ProfiBus DP node, which can be a multi-point I/O block.
Except cabling efficiency what other benefit profibus PA provides over profibus DP? At what number of devices we should shift from profibus DP to profibus PA. Next, how much is the cost difference between the two setup for a given number of field devices?
Profibus PA allows for a larger array of data to be queried and set in the device as compared to Profibus DP. Profibus PA is used to connect transmitters, actuators, and other analog devices to the network. There is a way to install Profibus PA in an intrinsically safe manner, whereas there is not with Profibus DP. Profibus DP is a faster protocol and is well suited for digital devices like motors.
Thank you for the simple explanation..
I am wondering if the Profibus PA is an replacement of HART protocol and what is the difference between these two protocols.
Yes, HART and ProfibusPA are very similar in the type of data that is provided between the sensor and control system. HART is somewhat simpler, since most analog sensor now come standard with HART and most analog I/O cards provide a HART interface. HART can be used regardless of the communication protocol used by the Remote I/O subsystem. ProfibusPA must use a linking device to transmit data to/from the sensors as well as 24VDC power. HART uses loop power from the control system analog cards.
I noticed Profibus is being used on the Honeywell Intelligrated Intelisort. Can someone tell me what type of Profibus is being used for this system? I am the new guy on the block, and I am interested in training on Profibus. Any advice on top training providers specific to Profibus.
The Honeywell Intelligrated Intellisort system uses Profibus DP. Realpars has many videos featuring Profibus use in Siemens PLC systems. There are a number of TH-cam videos (like this one) that can give you basic training in Profibus. The Profibus International organization has courses to become certified in troubleshooting or network design if you need more formal training or certification.
Most of videos are really outstanding... thanks for each and every video

how does the communication occur with the segment coupler (in terms of addressing) of the I/O's with the PLC?
Great question!
The process varies depending on the specific programming software you're using. Take, for instance, Omron, Allen Bradley, Siemens, and others. Explaining the intricacies within my response would be quite an information overload. However, I can certainly share that when you're working on programming your network, the software handles the addressing details. To delve deeper, I'd recommend checking out this informative resource on Siemens. It provides an excellent explanation and more in-depth information that might just answer your queries.

Buenas tardes, gr por el vídeo, pero este me generó algunas dudas:
Que voltajes manejan y que tipo y cantidad de información envía cada uno, los cables son iguales o que diferencia tienen?
Gracias por su pregunta. Primero los cables son diferentes. Debes utilizar un convertidor de DP a PA como mencionamos. Utiliza un cable DP antes de su convertidor y luego, dependiendo de sus dispositivos, debe usar el cable recomendado como se menciona en las especificaciones del convertidor y sus dispositivos, que debe ser un cable común. Puede agregar fibra óptica según sea necesario para sus dispositivos y convertidores adicionales para la fibra óptica. Los vendedores pueden proporcionarle información.

profibus connection betweeen nodes and segments addressing also
it's easy to connect a siemens plc or a scalance with profibus, but what about a sensor? how does a sensor connect to profibus? for example a thermocouple probe?
A sensor needs to have a Profibus interface built into the sensor. Typically, for these sensors, this will be Profibus PA. Profibus is a 2-wire system that has special connectors for use with Profibus PA sensors. Usually, an M12 connector is used. A thermocouple probe would not connect directly to Profibus. It would need to be connected to an RTD card in the PLC system or be connected to a transmitter that has a Profibus PA interface.
Could you make a video about valves and positioner ?

Does ti505 siemens old models can still connect with new models of profibus dp drives
Profibus DP has had a few versions over the years: V0, V1, and V2. All versions are backward compatible, so as long as the master (the PLC) is at or above the revision of the connected drive, communication should work. Many devices have a selectable Profibus DP version selection that will allow the device to work with CPU's at a previous revision level.

Thanks for your comment and suggestion, Kshatriya! I will happily pass this on to our course developers.
i have one query. in PA we have connected segment coupler.. but to connect to i/o
Yes, a segment coupler allows a Profibus PA segment to be connected to a Profibus DP segment, which is required to be accessed by the PLC's DP port. Profibus PA is designed to connect directly to the process sensors without the need for a remote I/O rack or interface.
Are the same type of sensors / transmitters used for profibus DP or PA? The PA seems very similar to foundation fieldbus setup while the DP follows the 4 - 20mA convention.
ProfibusDP, ProfibusPA, and FFB are all based on the same physical layer (RS-485). However, that is where the similarity ends. Sensors made for each of these three protocols are NOT compatible with networks of the other two. Sensors are typically provided with one of the following interfaces: 4-20ma/HART, ProfibusPA, or FFB. So yes, ProfibusPA and FFB are very similar, but not interchangeable. Devices such as scales, motor controllers, VFD's, and some analyzers are typically provided with one of the following interfaces: 24VDC/4-20ma, ProfibusPA, ASi, or DeviceNet.
@@realpars many thanks.
What are the main differences between Profibus PA and Profibus DP?
Profibus DP is a high-speed (up to 12Mb/sec) RS-485 serial network that can be used to pass data from devices such as weigh scales, remote I/O racks, VFD's, and other devices that typically have large embedded data tables. Up to 128 nodes can be placed on one Profibus DP segment. The bus is an active powered bus that requires termination resistors at each end of the segment. The segment is connected to each node in a multi-drop configuration. Profibus PA is used to interface process sensors to the control system. Profibus PA operates at 31.25Kbit/sec, but the amount of data shared with each sensor is relatively small, and data update rates are typical for a process sensor (about every 0.25 seconds). The physical of Profibus PA is Manchester-coded bus powered (MBP). At the communication protocol level, Profibus PA and Profibus DP are identical.
What is the difference between profibus PA and foundation feildbus ?
Thanks for your comment, Mohammed! Great question, this would make for a great topic suggestion. I will go ahead and pass this on to our course developers.
Happy learning!
Very simple...straight to head...thanks
Amazing, Kamal!
Doesn't this bring too much adresses on the profibus? A lot more thicker wiring because every sensor is on the bus?
Great question! Answer: No. The limit per segment of Profibus PA is 32 nodes. For Profibus DP, it is 125 nodes per segment. This is not a problem for addressing, as the Profibus master or link coupler is able to handle up to the maximum number of nodes and the maximum memory per node of 244 bytes. If you do the math, for Profibus DP this is only ~31k of data and for Profibus DP this is only ~8k of data.
If we remove I/O modules then how plc will know, which I/O device has sent the signal, and how you will provide isolation between cpu and supply??
For Profibus DP, the position of I/O cards in remote (and local) racks is defined by the hardware configuration which is downloaded to the CPU. If you remove a card, the hardware configuration will need to be updated. For Profibus PA, each sensor has a unique node address. If you remove a sensor, that node will no longer communicate, but that will not affect any other node. Independent power supplies are used to power Profibus segments, separate from PLC/CPU power.

In my factory profibus is running how can I know that is PA or DP?
The best way to tell is to inspect the hardware configuration for the system you are using. Other ways to tell: Profibus DP cables usually have purple jackets and Profibus PA usually has orange jackets. This is not a foolproof method, but if cables meet the standard, this is an easy way to visually inspect for DP or PA. Another good way is to see what devices are on the Profibus network. If you see VFDs, drives, weigh scales, etc., connected by 9-pin connectors, it is Profibus DP Often, the interface card they are plugged into indicates Profibus DP on the hardware port. Profibus PA networks typically use passive connection blocks, usually with M12 connectors, and are used for transmitters, analyzers, and flow meters, etc.
is profibus pa reliable? in separate io system isnt it easier and safe to maintain?
Thank you for your question. Yes, it is. PA is a bit slower and made for another type of application compared to DP, but they use the same protocol. Here is a link for your learning. us.profinet.com/what-is-the-difference-between-profibus-dp-and-pa/

@RealPars but how does it differentiate between the sensors on a PA bus? Does the sensors have some sort of ID? should we use some different kind of sensors on a PA bus?
Thanks
Each node on a ProfiBus-PA network has a node address (0 - 31). This can be set by DIP switches on the device or via a configuration interface at the device. Only devices with a ProfiBus PA interface can be used in a ProfiBus PA network. If you have a 4-20ma transmitter and want to use it on ProfiBus PA, you will need to change out the electronics on the device. It is not as easy as upgrading from 4-20ma to HART, but ProfiBus PA will give you access to a whole lot more sensor-level data, configuration, and diagnostics than a HART interface can provide.
@@realpars THANKS A LOT FOR THE INFO.
Would it be correct to say that Profibus DP is the equivalent of Remote I/O racks in an Allen Bradley controls system?
You can make that analogy. For Remote I/O racks that contain I/O cards and are connected to the main CPU through the use of a Profibus communication interface module, the similar system in the Allen-Bradley system would be Remote I/O racks that contain I/O cards and are connected to the main CPU through Ethernet/IP. VFD's can be connected directly to the Profibus DP network (with the proper interface in the VFD) jut like a VFD can be connected to Ethernet/IP (with the proper intreface card).
What are the differences between profibus pa and foundation fieldbus
Both are similar but distinct protocols. Both use single twisted-pair, shielded cabling and require termination resistance. Both are based on the same physical layer, so the previous similarities are expected.
There are many differences. FF is publisher/subscriber based, and can be directly connected to a card in the PLC or DCS via FF H1; PA is master/slave based and requires a gateway or link coupler to be connected to the PLC or DCS (usually linked with Profibus DP). For FF, I/O is mapped via embedded standard function blocks, whereas PA uses customized GSD files for mapping of device models. Typically, 8-12 devices are able to be connected to a segment. For PA, up to 22 devices can be connected to a single segment.
I have used both extensively, and both perform well in the industrial environment. The key is planning and understanding of the limitations of each protocol (total power available, connectors and terminators, data update rates. etc.).
