More than anything: When you said pressing up arrow brings the previous command. I love it. Most of the videos are skipping this kind of part which is helpful in the real world. Thank you for such an informative and great video.
You are welcome Rahil.
I missed that part but got it through your comment and tried it. Thankyou sir for your comment.
I am a fresh graduate of Canada and am looking for a job in the automation sector.
Hey guys, thank you for this video! Most videos and at work did not cover this simple but vital step in connecting. Keep up the good work!
Glad it was helpful!
It´s correct that rule you commented on the video, and that´s why a subnet 255.255.255.0 means a device is living in a network represented by the first 3 bytes of its IP network like: 192.168.1 in this case the last number "10" represents the host number, and you can select between 253 host numbers, if the subnet mask was 255.255.0.0 the numbers you need to make sure are the same are de first 2 bytes like: 192.168, i´m sorry if i make mistakes writting in english.
wow great job, so informative. fixed my issue right off the bat. Thanks guys!
Glad we could help Adrian!
Great video it was very helpful. It was easy to follow and explained things just enough to understand but not over complicate. was finally able to connect to my PLC.
I'm glad you found it helpful and not too complicated. Working on an upcoming video on how a PLC scan works. Hopefully I can keep it simple :)
The best video ever, helped me solve a huge problem. Thanks a ton :)
I'm glad you found it helpful and thank you for the compliment.
Thank you! This is exactly what I was looking for.
Glad it was helpful!
Thanks much Tim and Amber! This is always a pain for this old industrial electrician guy!
Glad it helped you out John. It is a pain for so called "experts" also 😜
Once again Tim, you got me out of a jam. I had changed the IP address on the wireless network setting, not the LAN. This is a shared laptop and when it gets used on another plc, we need to change the ip address back and forth. Thank you.
You are welcome!
You guys are awesome. I am connected and I actually understand what is going on now. Thank you.
Wonderful, glad we could help Mike!
Great and very informative!!
When I first saw this comment I thought it was on the "How to respool or not respool video" video from yesterday. A little less informative but at least entertaining for Amber :)
excellent video congratulations on your channel greetings from Venezuela
Hello and thank you!
Nice job using CMD>Ping and showing how to do the basic checks. Knowing your own IP is kinda important! In the controls world....it seems like "static" is king....unless the administrator is aware of what you need to be able to see on the network!! But again, static is what seems to be the item to prevent confusion/frustration. (HVAC Controls - Alerton & PLC)
Yes, static makes things easier.
Again, thanks again. You are the best.
You are welcome!
Man you guys are awesome! You nailed this for me, I am just a dumb when it comes to this, I am a Materials Scientist but this is just out of my scope man. Thank you so much for this help.
You are very welcome Matthew!
This saved me. Thank you!
Glad it helped!
I found it!!! yaaaaay!!! this was super helpful. I'm an IP dummy (but working on it) and you got me understanding it well enough to connect. Thanks so much!!!
Hi Celeste. Glad it was helpful!
I am really helped. I had this problem with a s7-1200 and it could not be pinged. This helped very much. Thanks.
You are welcome. I'm glad you found it helpful.
I have a click and I want to control a motor in my home for learning purposes. What do I need to connect to the contactor ? Plc is DC, can the relay accept a dc signal ?
Great Video, thank you so much. I'm talking to my PLC's over Ethernet.
You are welcome.
Thank you heaps, sorted my issue
You are welcome Brett.
Thank you so much!
You're welcome!
I am glad to see your prompt reply, it half the headache of my tension. but still RXLinx is not catching up SLC 5/3 cpu. I still missing something. but thanks anyways.
I thought you were having trouble configuring your IP address, if so you shouldn't be in RsLinx.
Great video
Thanks Mitchell!
Thanks a lot dear,GODbless you
You're welcome 😊
You did a great job explaining that but the issue I'm having is that I know the IP address of both my laptop and PLC and they once connected, but now they are not. That same laptop connects to my other two identical PLC's but not with the 3rd one. The 1st 3 fields of the laptop ethernet IP address matches those of the PLC so it did connect but now I suspect that the IP address changed on my PLC. How do I go about finding the IP address on my A.B. Micro820? If I can get that IP address then I probably can get the two devices to communicate.
Yes it sounds like either the IP address has changed. The easiest way would be to use the PLC Tools SIM-IPE to read the IP Address www.theautomationstore.com/ethernet-ip-address-explorer-dhcp-and-bootp-server/
Can you help me to troubleshoot my recycling plant Scada issue
Maybe, but you would probably be better off asking a question like that at plcs.net.
Hi Tim i have a device connected to my PLC, i can ping it but won't schow on rslinx. do you have any idea how i can solve this issue ?
What driver are you using in RsLinx and what are you connecting to?
Hey, what protocol is used to configure those.
CIP which is part of the Ethernet/IP protocol
How to connect my PC with PLC if I don't know the IP address of my PLC? NB. I want to connect with SLC 5/05 while I dont know the ip address of my PLC. When I connect ethernet cable to PLC, see only ip address of my PC adapter by ipconfig.
You will need to discover the IP address with a device such as the SIM-IPE.
plctools.com/plc-tools-sim-ipe-ethernet-ip-address-explorer-dhcp-and-bootp-server/
I have used BOOTP DHCP tool RSLinx tool using same subnet mask, but it didn't show Mac address of my PLC. However when I connected ethernet cable to PLC, signal LED turned ON on the module. Now, do I need to cycling PLC power or any other means?
@@shahriarshajib541 Hard to say, Rockwell's BOOTP-DHCP tool isn't very reliable.
Hi, I'm still not getting ip address on my laptop on windows 10. Can't find local area network in it.
Please be advised. Thanks
Go to Control Panel then Network and Internet and you should be able to find it. Good luck!
My related question is, everytime PLC plugged to PC ethernet, I lost connection to WIFI network, PC automatically switch to LAN and disabled WIFI. do you have a tutorial video for that?
Hi Nick. No and I have had the same issue in the past. I think it had to do with the network bindings but that's a little out of my league.
Sir how to find out plc module up address sir,,,, please make video sir
Lots of videos on that, see link below.
plctools.com/plc-tools-sim-ipe-application-examples/
please could you help me with a HMI maple i am attempting communicate but i ccould not my plc is micrologix 1100
I'm not very familiar with the Maple but you'll be looking for DF1 over Ethernet and make sure your IP address is configured and on the same network.
What about port conflicts on windows 10 using rs5k 16.5
Not sure what you are asking Ronny. This video is about Ethernet connections. For AB as long as ports 2222 and 44818 are open, you wouldn't have a "conflict"
@@TimWilborne on rs classic i kept getting a port conflict but couldn’t find why ima look into those ports , do you think this can happen because im trying to use it on windows 10 hom edition with vm ware ?
I'm a little bit confused. About 2 min in you said to make sure the IP addresses match and then you immediately said they shouldn't match or you get a duplicate?
As a general rule, the first three octets most March and the fourth one cannot. So for example both should be at 192.168.1.X but the X must be unique to each one.
Great video!!I have been trying to troubleshoot my PLC at school, and we have tried to use our IPv4 address method but it seems that it doesn’t save to our server. I have been trying to find the video where you explain how to troubleshoot the PLC in school environments? If someone can share that link it will be greatly appreciated!!🙌
What PLC do you have?
Hello sir ..
I have allen Bradley plc5 , when communicating with plc online for trouble shooting , cross reference is not enabled . So let me know to fix this issues. .
Different versions of the software have different features available. I'm really rusty with RsLogix 5 part number and features but if RsLogix 500 followed it then on the basic license, the cross reference feature is disabled.
@@TimWilborne how I can sort out this issue and thanks for replying ..
@@ravindradesai5007 You would need a different version of the program but it is obsolete so I wouldn't recommend purchasing it.

Is there a chance that the processor is just bad or maybe a bad switch?
That is always a possibility but it wouldn't be my first guess.
Do you know any miltary jobs that involve automation or plc?
Yes there are a lot of military jobs that involve automation and PLC's.
@@TimWilborne I thinking about joining air Force is there a way you can list them ?
@@actorperfomance101 Air craft, air craft carriers and drones quickly come to mine. The stealth bomber couldn't even stay in the air without automated flight controls. Some of the best in the industry came out of the military. Good luck!
@@TimWilborne ok thank u I really appreciate it
Hi! I was thrown into a factory where no one has plc experience and where I'm still a bit of a beginner myself. This video helped with my main issue! Now how can I know what program to run? (Rslogix 500, rslogix5000, studio 5000, etc) because no one at my place knows
That is a tough one along with which cable! SLCs and Micrologix use RsLogix 500, Controllogix and Compactlogix use Studio 5000 or RsLogix 5000 depending on which version, and Micro800 uses Connected Components Workbench.
Thank you so much!
I seem to have the IP configured correctly, and RSLinx can see my PLC. I also have set up this PLC in RSLogix, but when I attempt to Go online, Download or Upload I get an error message "No responce from processor at selected path/node!" and "DiagnosticStatus failed: 0x4". But thanks for the video, it got me further that ABB documentation did!
If you go to System ? Sys Comms...can you navigate to your PLC then go online?
I tried this the first time and came back with a different error, and I noticed my PLC had fault light flashing. Turned it off an on again, restarted RSLogix and did the same and it worked. Thank you for you help!
@@jamespopejoy4176 Glad you got it working James!
How to fix Ip address not connect ( Destinatiton Host Unreachable ) ?
Check that your PC and PLC are on the same network and subnet. So for example is your PLC is 192.168.1.10 with a subnet of 255.255.255.0 then you PC should be something like 192.168.1.123 with a subnet of 255.255.255.0
I Already did. The result is same.

If i keep playing with this trainer and keep watching these videos people might get the wrong idea like i can flub around in the PLCs that are running galzillon dollar processes.
You will be able to!
Thanks for your help. I am trying to connect my pc to my programmer device
Great. Did you get connected?
@@TimWilborne hi Tim. No. I got it wrong. Its my usb to plc. But i still cannot go online. It keeps saying my plc is not a 500series plc. But i can see it on the rs500 software. But cannot go online.
Thank you very much for your video. But please make a video about how to configure an IP address for a new AB MicroLogix 1100 PLC . Thanks

Do you know the default ip address for the 1769l33er controller
By default it will not have an IP address. It will have DHCP enabled so that one can be assigned to it.
@@TimWilborne ok. So i will have to go to rslinx to set it right
@@TimWilborne i recently downloaded my existing rs500 onto a new pc and my license got transfered over. I spent a week or so trying to bring it back to my laptop. Now i can open rs500 on my lt but i cannot go online. I can see the hardware but cannot see the program. Usb to 1769
@@proadlekopy Are you saying you are connecting to a 1769 PLC such as a Compactlogix? It uses Studio 5000, not RsLogix 500.

@tim do you know how to fix this
i have plc slc 5/03 and i want to conect by ethernet what i need to do or configure in my pc for conection by ethernet devices?
You can't! STOP! That isn't an Ethernet port on the top of a SLC 5/03. It is a RS485 port and needs a 1747-UIC for communication. Additionally the incompatibility in voltages between it and an Ethernet connection can damage both ports. Learn more at this link.

@@TimWilborne thx sir
So, you have gone thru all these steps and STILL, YOU cannot connect........maybe the Eth port is bad? Of course, if the customer reports, "I can't talk to this device anymore"....likely a good first hint. So you do all this and the same results!? Funny, I just got a 1400 and nobody told me what was wrong with it.......so messed with it, did the checks, and sure enough, that Eth port is no good. Could not even get a response to a ping!?
