I'm need to communicate two TWIDOS plc's, using modbus TCP/IP, but I need to know which instruction I have to use for the ladder logic. I already tried the way of modbus RTU.

one needs to be set to master the other as a slave.
I have only setup modbus to a PV screen so I am unsure of any further detail.
 
Iant, thanks for response,
I have them identified as master and slave. Do you think that I have to use the same instruction format as in modbus rtu in twido?I means the funtion codes, and so on?.

Regards
