I want to exchange data between 2 PLC of different trademarks with holding registers .
For the moment I can't test the communication , N° ID slave mobus TCPIP doesn't appear in settings, when commissionning .
Is the %IW really for holding registers ? Strange ? it should be %MW ? No ?

Hi,
I'm trying to get my head round this too!
I think it is that the Slave is writing from that holding register on to the Modbus with the offset you specify.
If you figured it out i'd be more than intersted to know what you did to solve it.
Kind regards
Edd
