I HAVE A S7-400 REDUNDANT PROCESSOR AND I/O CHASIS REDUNDANT, I WANT TO PUT A PG IN THE CONTROL ROOM, I HAVE A REPETER RS485 TO BUD THE COMUNICATION CABLE TO THE CONTROL ROOM IS A MONOMODE OPTIC FIBER, HOW I CAN COMUNICATE THIS PG.
Is it possible to connect sensor controllers to the remote I/O and then use Profibus to carry the signal to the PLC? If so, what cabling should be used to send the signal from the sensor controller to the remote I/O?
Absolutely! That's the whole point of using the remote I/O. For connecting a sensor to a remote I/O, a normal 20 AWG wire (0.5 mm2) does the job. For example, if you have 10 sensors in the field, you need to use a cable which includes 10 * 20 AWG wires. After you connect the sensors to the remote I/O, you then use a RS-232 cable to connect the remote I/O to the PLC.
Thank you so much for your kind words and support! We're thrilled to know that you're finding our content valuable. Your feedback motivates us to keep creating!
If a DP is failed to transmit a data then what to do. As per video main signals are directly connected to i/o modules but I think in industries all signals are useful.
PA stands for PROCESS AUTOMATION. Profibus DP is being used for communication bètween master and slave lile controllee and field device , while Profibus PA is helpfull in communication between master amd master like 2 or more different controllers.
Your in depth explanation with small video is very useful. Please also make a video on all other communications/ network used in automation. Like ProfiNET. Thank you.
Thank you for your question. We could move the PLC to a remote I/O panel, but automation engineers typically keep CPUs in a more environmentally-friendly location. But you are correct; the PLC could also be placed in a Remote I/O Panel and communicate via Industrial Ethernet to the plant network. Profinet is one type of Industrial Ethernet, but it is most often used for Siemens systems.
thanks for video. I have one question. Let's say that I have SCADA and PLC. Distance between them is about 3km. What is in your opinion best method to connect them? Profinet, Profibus, Optical Fiber cable...? What is the cheapest solution? Best regards
For a 3km run, only fiber optic will be suitable. The maximum length for Profibus transmission is about 1.2km (1200m), and for Profinet, it is the same as for Ethernet (100m). Fiber optics can be run 25km or so, but the cable is relatively expensive (US$10,000 per km installed). 3km is in the domain of Remote Telemetry Units, which collect data from the source (PLC) and send it to a host (SCADA) via Cell Phone signal (GSM/CMDA) or radio frequency. Cell-based communications carry a monthly access charge, but the initial investment is quite low compared to fiber optic runs of that length.
Great video! Is this video in your website, because I searched there and didn't find nothing. Do you have other ""communications videos" in your website? which are? thanks!
Sir, your videos are very helpful regarding Automation...But Can you make a video on control valve details, their selection criteria & regarding Cv calculations for control valves..etc..?? Please...we are waiting...thank you...
Hi dears. Very good and useful video. I am asking you for advice if I want to start learning the PLC and automation systems, from where i can start and what is the best way to do this?

Boith Profibus and Modbus are based on RS-485. Profibus has certain protocol features that let certain versions of it operate in multi-master mode on RS-485, while Modbus can be only single master. Profibus is a much more advanced protocol than Modbus. For example, Modbus is limited to 32 nodes on a single network. Profibus can have 126 nodes on a single network (with repeaters). Profibus uses bus-powered Manchester encoding, half-duplex. Profibus uses a multi-drop network topology, the same as RS-485.
Forgot to ask: Is the use of Allen Bradley FLEX I/O’s out in the plant at each equipment control panel all connected back to the Main Logic Controller via Ethernet bear any resemblance to Profibus net design or is it similar just with an Ethernet connector vs a RS485..The only cable running back from every equipment control panel was a single Ethernet cable all connected to many Statrix 8000 switches. Looking back this seems similar quite so to me, just different connector RS485 vs Ethernet IP.
There are many protocols and buses that can be used to connect an I/O rack to a PLC. With Ethernet/IP (the version of Ethernet used to connect to Flex I/O racks), a CAT5E cable (4 twisted pairs, although only 2 pair are typically required) with RJ-45 connectors is the typical configuration. For ProfibusDP, a 9-pin connector (4-wire) is used. ProfiNet is typically uses the same cabling as Ethernet/IP and can use RJ-45 connectors, but I do not believe that there is a Flex I/O adapter for ProfiNet, only for Profibus DP. There are many gateways that can be used to bridge between dissimilar networks and protocols, so it is possible to design a system that uses many different protocols. ProfiNet is very similar to Ethernet/IP and both are based on IEEE 802.3, but they are not strictly interchangeable, even though the same cabling can be used.
Hi Jay, Sure! We have a course library filled with PLC courses. Feel free to have a browse around over here learn.realpars.com/collections Happy learning!
Nirmal K "PA" is short for "Process Automation". This industrial network works to connect field devices such as pressure transmitters, control valves, etc directly to the PLC or other control systems without using remote I/Os!

Why not move the PLC to the I/O cabinet and communicate with Ethernet? Setup a redundant Ethernet connection as well. Would that be Profinet?
Thank you for your question. We could move the PLC to a remote I/O panel, but automation engineers typically keep CPUs in a more environmentally-friendly location. But you are correct; the PLC could also be placed in a Remote I/O Panel and communicate via Industrial Ethernet to the plant network.

Hi there, happy to hear that! I will pass your request on to our creator team.
Great presentation!
really great training very well explained.
Please clear my doubt, whether the digital as well as analog signal runs through same cable??
Yes, but it would be more accurate to say the "digital signal and loop power" are run through the same cable.
Thank you for Clear information
You're very welcome!
Thanks, and I appreciate your sharing of knowledge.

how does Profibus PA work? is there a video explaining it just like this one?
Nirmal K "PA" is short for "Process Automation". This industrial network works to connect field devices such as pressure transmitters, control valves, etc directly to the PLC or other control systems without using remote I/Os!
TEPERGY thank you for your reply. So is it like Foundation fieldbus? . Do i have a communicator for configuring the transmitters?
Nirmal K No it's different than Fieldbus. Most of PA transmitters can be easily configured via the buttons available next to their display.
