Just for data sending and receiving

Both data exchange have to be in RS485 Communication

The MicroLogix 1400 has two important manuals:

MicroLogix 1400 User Manual:  1766-UM001

MicroLogix 1400 Reference Manual:  1766-RM001

The next questions are "what protocol do you plan to use" and "what are the other devices that you are communicating with".    RS-485 is just the physical media and electrical signalling level, and the protocol could be DF1 protocol, or Modbus protocol, or DNP3 protocol, or ASCII protocol.

I'm using modbus protocol for sending data and receiving data.

I'm receiving data through channel 0 as Modbus RTU Master and setting and No handshaking (RS485 Network)
