Sensor and actuator bus system for automation system

摘要

The bus system has bus lines (4) coupled to the interface modules (6) of the sensors and actuators (2) for bidirection exchange of signals, with a control unit (3) for cyclic interrogation of the sensors and/or actuators, coupled to a signal evaluation device (5). the interface module of at least one sensor and/or actuator is preceded by transformation unit (7) , with a second transformation unit (8) inserted between the control unit and the evaluation device, each converting the transmitted signals into a number sequence.
