Application and System Integration
The 6ES7141-1BF00-0XB0 connects sensors and actuators directly to the PROFIBUS DP network through its M12 connectors . It functions as a basic module within the ET 200X station, supporting up to seven expansion modules per unit . Moreover, the module features double-assignment capability on its M12 connectors for flexible wiring configurations . For operation, this unit requires connection to an ET 200X power module and compatible interface modules . Therefore, users should note that Siemens has discontinued this module since 2009, making it a spare part for legacy system maintenance .
