EthernetIP Help Please

[tcap]

Hello Mike,

The EtherNet/IP Toolkit is handled by the Industrial Communications Forum:

It looks like this question was moved over there after the first few posts:

http://forums.ni.com/t5/Industrial-Communications/EthernetIP-to-CompactLogix-PLC-help-please/td-p/31...

I recommend following up on that thread or starting a new thread on the Industrial Communications Forum.

Hello Tom,

I posted here because I received more help here on this forum (from Sanjay) than I did on the Industrial Communication board.

Hi,

  It will read and Write tags based on your loop Execution time and should be in Milliseconds time.

have to able to read/write tags in your program?

[wd8ivl]

Yes, I am able to read and write tags now. 

Was just wondering how fast the PLC updated the Controller Tags...I guess that's a question for Allen Bradley.

Hey Mike,

  Yes, you are right, It is for Allen Bradley people to let you know. as far as i know PLC scanning is ms timeframe depending on type of PLC( Compact Logix/Control Logix etc) and Memeory, speed of processor etc.

Hello Enrigo,

  I think you need to be specific what exactly are the issues you are having. VI as per presentation should work.

you make sure sure your PC IP address and PLC IP address should be on the same network for example if your PC IP address is 192.168.1.15 then your PC IP address should be in the range of 192.168.1.xxx( where xxx is 0 to 254 except 15 because you already use 15 for PLC)

 make sure your subnet Mask is also the same for both, otherwise you will have networking issue.

you can check  if your PC and PLC are talking to each other after you give them their respective IP addresses by pinging in DOS prompt.

Thanks

Sanjay
