1769-SM2: DSI/Modbus Module
The 1769-SM2 is the DSI/Modbus Module covered on this page. The attribute that decides whether it fits the existing installation without modification is -10…50 °C (14…122 °F).
What separates this variant from its siblings is dsi/modbus module. A communication or network module is judged by the protocol it carries and the bus it joins, not by its catalogue headline. dsi/modbus module sets which controllers and field devices it can bridge, and the isolation and termination it provides. Matching -10…50 °C (14…122 °F) against the existing network topology avoids a module that fits the rack but cannot talk to the rest of the system.
