Why Can't I Connect to my PLC over Ethernet? 

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.

Glad it was helpful!

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 :)

Glad we could help Adrian!

Glad it helped you out John. It is a pain for so called "experts" also 😜

I'm glad you found it helpful and thank you for the compliment.

Glad it was helpful!

Wonderful, glad we could help Mike!

You are welcome!

Yes, static makes things easier.

You are very welcome Matthew!

Hello and thank you!

You are welcome. I'm glad you found it helpful.

You are welcome.

Hi Celeste. Glad it was helpful!

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 :)

You are welcome!

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/

Glad it helped!

I thought you were having trouble configuring your IP address, if so you shouldn't be in RsLinx.

CIP which is part of the Ethernet/IP protocol

What driver are you using in RsLinx and what are you connecting to?

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.

You are welcome Brett.

Go to Control Panel then Network and Internet and you should be able to find it. Good luck!

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.

Maybe, but you would probably be better off asking a question like that at plcs.net.

What PLC do you have?

Thanks Mitchell!

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 ?

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.

Hello sir ... How to set preset time for timer in Allen Bradley PLC5 online

@@ravindradesai5007 Check out this lesson, it is for RsLogix 500 but RsLogix 5 is the same. www.theautomationstore.com/rslogix-500-training-timers-ton-tof-and-rto/

You're welcome!

You're welcome 😊

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.

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!

Lots of videos on that, see link below. plctools.com/plc-tools-sim-ipe-application-examples/

That is always a possibility but it wouldn't be my first guess.

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!

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

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.

This video will help. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-W7Q5ZgvEWiw.html

Here you go. plctools.com/plc-tools-sim-ipe-reading-and-writing-an-ip-address-to-an-allen-bradley-micrologix-1100-1400/

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.

@@iyingkziril2348 What type of Ethernet device is it and what is it's IP configuration? If you go to the command prompt and type "ipconfig", what does it say?

@@TimWilborne Hey Tim, I've been running into the issue iyingkz irii was having on an S7-1500 PLC: 192.168.0.123 subnet 255.255.255.0 PC in VM after ipconfig Ethernet adapter Ethernet0: Connection-specific DNS Suffix . : Link-local IPv6 Address . . . . . : fe80::b1c4:9ad2:5bed:4333%8 IPv4 Address. . . . . . . . . . . : 192.168.0.123 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : Ethernet adapter Bluetooth Network Connection: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . :

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. Here is more information www.theautomationstore.com/studio-5000-training-where-can-i-download-studio-5000-logix-designer-rslogix-5000-and-what-is-the-price-difference-of-each-version/

@tim do you know how to fix this

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.

You are welcome!

Here is a lesson series on Studio 5000. twcontrols.com/controllogix-compactlogix-studio-5000-lessons

@@TimWilborne thx sir

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. www.theautomationstore.com/how-to-configure-the-1747-uic/

You will be able to!
