1.2 Product Overview
The SGW1-IA3-MMP is a Modbus communications multiplexer / converter over serial ports. It
allows you to connect Modbus RTU / ASCII masters to Modbus RTU / ASCII slaves. Each of
the serial devices can operate with Baud Rate, Data Bits, Parity, Bits Stop and different
Modbus protocol type (RTU or ASCII).
The SGW1-IA3-MMP orders the interrogations coming from the different masters assigning a
priority according to the order of arrival of the different masters, and then sends them to the
slaves.
As an additional function, the device allows the exchange of information between Modbus
masters through the 1000-byte exchange memory that can be read and written by any of the
connected masters.
