Omron C200HE Remote IO problem

[nuwan]

Hi!

I am having a problem with the C200HE. It has a SRM21-V1 communication module with SRT1-ID08 remote input module. I think the protocol used is CompoBus/S.

I uploaded the program using CX-Programmer and did some changes. After that I downloaded it again. I found out the IO table was missing. So I have created the IO table.

The program addresses for the remote IO are from 108.00 to 108.07 . But now any change to the inputs of remote IO SRT1-ID08 are not seen in the program when online.

(I do not have "Rack/Slot start addresses" in options of IO table. ) I have attached some pics of the project.

How can I map these memory bits to the remote IO again ?

Thank you in advance.

Figured it out !!

I figured it out. There is nothing to assign. The starting address of the communication module is DI110 in my case. (Which is shown in IO table)

So according to the manual of the communication module ( http://hjsfa.co.kr/files/2015/06/C200HW-SRM21-V1.pdf ) my SRT1-ID08 remote module starting address is DI118. (Because I have set the node as 0000 from DIP switches)

So compoBus/S is not that hard after all.
