Sensor / Actor

Safety functions for sensor/actor processing deliver massive simplification in terms of programming. The programming work for the logical/temporal comparison of multiple inputs on the safety sensors is not required. Instead of this the required processing can be selected quickly and easily using the peripheral configuration menu. Each input and output element only appears in the programme editor is a function block, already reduced to a single logic signal. Conventional safety controllers are restricted to logic processing or to the reduced word processing of data. A safe drive monitor such as that required in the European Machinery Directive is therefore difficult to achieve. The SMX series, on the other hand, delivers complete future-safety. Using the safety functions integrated in the firmware for drive monitoring, the new tasks can be implemented quickly and efficiently.
