14.1. Modbus Server

Modbus server allows application tags, virtual tags, or IO tags from any IO drivers to be grouped into any number of virtual Modbus devices. Each virtual Modbus device is splitted to four major categories, which are coil outputs, digital inputs, analog inputs and holding registers.

The setting needed to define a Modbus server is the port number.



Configure the Modbus TCP serber port number. Default port is 502.
