Connection modbus tcp client and more server devcies

Hello,

I'm struggling with the same issue as this topic on the forum: 

Connections modbus tcp - one client(s7-300) and two server device

But I have some questions how to set this up.

I'm working in STL and working with a CPU315-2DP V2.0 and CP343- Lean V2.0

a) How do I set up the second device in NetPro, Connect to same Ethernet network probably, but where I have to change de connection ID from 1 to 2 for the second device?

b) How do I configure this in OB100? Copy DB100 to DB101 or modify OB100? How do I do this?

c) How do I configure this in OB1?

Who can help me with this?

Best regards.

Hello, 

thank you for helping me.

I've attached a screendump with Ethernet settings, is this how to add the second slave?

Best regards.

Hello,

I've added the connections now. See attachment (screendump and project archive)

I added a second network in OB100 with slave02 and also added network in OB1 with second slave.

There still is no communication with second slave. What can be wrong here?

Best regards.

Hello,

Thank you.

yes I deleted the OB's and focused on connection.

I changed so the second port is 502 now too.

With some tricks (comments in OB1) I now can communicate with slave 1 or with slave 2. 

Must it be possible to start communication with slave 1 and 2 parallel? Or do I have to first finish communication with slave 1 and then start with slave 2?  (And when slave 2 is finished then start again with slave 1 etc)

Best regards.
