Ethernet IP toolkit Omron CJ2M PLC

[LewisL]

You are welcome, Rick. And thank you for sharing your knowledge. 

I think your question in this step is more related to the EIP format differences between two Omron PLC types. 

I'll keep monitoring this thread and give my help if I know better.

Dear Sir,

I am facing same problem with Communication between NJ series PLC.

Any solution you found to read and write boolean data type? Please help.

Thank you

Hi Ishan,

This thread is a couple of years old, so I suggest posting in a new thread to make sure you get responses to your question.

Cheers,

Hi Ishan,

I have not worked with the NJ series yet. This is what I have for the CJ series. Sorry, the attachments are Labview 2014 format. So I took a couple of screenshots.

The Host IP for my setup is 192.168.250.1,1,0 and the Tag Name is the Symbol name created in CX Programmer.

Hope this helps.

Regards

Rick

Dear Sir,

Currently I am also working on CJ Series & I use ETN-21 Card.

I got the network path error.

How to Configure ETN-21 Card?

I found this document put out by Omron for connecting an NJ to an Allen Bradley PLC. Not sure if it helps with your issue or not.

GREAT JOB rpage !!!!
You're my savior!!
I was using the unofficial ethernet/ip with AB PLC and I was looking for a solution to make it work with OMRON PLC and here I found the answer.
I was able to read string and boolean using RAW datatype and real using the REAL vi. But no way to write.
Following your instruction and your example, now i can read and write every kind of data i need.
Maybe if I have some spare i will post some VI ready to be added to the toolkit.

I supposed to but not... I Can't write REAL datatype.
I'm not sure on How to build the byte array to write to make the array acceptable for the write.

I Have to use CA as datatype but then? If I had to write a number like 202,00?
