Setting up a serial interface

General

The configuration for serial interfaces and their protocols is done via two nodes:

• One node represents the common serial parameters related to the hardware port.
• The node below represents the parameterization for the particularly attached protocol.

Protocols currently supported by AC500 V3 PLCs

• 3S CAA SerialCom (common serial communication, send/receive data Configuring CAA SerialCom on serial interface)
• MODBUS RTU (client & server Configuring MODBUS RTU on serial interface)

How to switch between the protocols, see Configuring CAA SerialCom on serial interface.
