How to change Service code in EIP

[imhht1311]

Thanks for reply.

So, I tried to communication OMRON PLC using Ethernet/IP Driver in WinCC OA.

I set up
- Common settings : ControlLogix
- IP Address : OMRON PLC's IP Address
- Slot number : OMRON PLC's Slot number
- Timeout(ms) : 50000

-Connections : 1
- Message size : 500

Sadly, There were two problems.

Firstly, I saw packet using wireshark.
and packet showed
- Originator Vendor ID : Real Time Automation(C&ID) (0x0032).

so, I receive "Connection failure : Connection Manager - Forward Open".

I set up same in Kepware to compare WinCC OA's packet
and then, I saw packet that packet showed "Originator Vendor ID : Unknow(0x051b)"
and I receive "Success: Connection Manager - Forward Open.

Connection could not be made on WinCC OA even though it was set to the same protocol.

setup information is in this link

secondly,
Perhaps the service code Ethernet/IP Driver in WinCC OA and Omron are different.

In order to read Byte data, OMRON's Service code is 0x1C.
but perhaps WinCC OA's Service code is 0x52.

So, I want to change this.
What can I do?

I had a short discussion with our developer and checked the documenation.
A connection to OMRON PLCs is officially not supported by the WinCC OA EIP driver.
We have not tested them and therefore we do not know if the work or not.
