The Schneider Electric TM171ASCTB27 is an expansion communication module for the Modicon TM171 / M200 Logic Controller series. Specifically, it is a CANopen Master interface module that adds a CANopen fieldbus communication port to a compatible TM171 base controller. This enables the controller to connect to and manage a network of CANopen slave devices (such as drives, I/O blocks, sensors, or other controllers), significantly expanding its connectivity and control capabilities.
