Rs485 Sio - IAI RoboNet Operation Manual

3.4.4 RS485 SIO

Two modes are available: the Modbus gateway mode in which the unit operates as a Modbus/RTU slave station, and the SIO
through mode in which the unit operates by means of serial communication per the Modbus/RTU and ASCII protocols.

*1: The baud rate is set by the gateway parameter selection tool.
*2: If the host is a PLC, the PLC must have a RS485 or RS232C interface. If a RS232C interface is used, a SIO converter
(RCB-TU-SIO-*) is required.
