Hello everyone,
I would like to know if it is possible to use both TCP Modbus Master communication on a SNAP PAC R2 PLC and Modbus serial slave communication on a communication module SNAP-SCM 485 ?
Hello everyone,

I believe the answer is yes. Are you trying to slave via scm and master with R2 on same rack? If so yes.
Hello Helpme33,
The SNAP-PAC-R2 is a Modbus/TCP slave device as it comes from the factory. (No extra programming needed.)
You can also turn it into Modbus Master via the subroutines (like a library of commands) in our Modbus Integration Kit. This same integration kit includes slave subroutines for both TCP/IP and Serial.
I hope that helps!
