3 Methods for Safety Programming
3.5.2

Standardizing actuator control

Recommendation
Create a separate function block for each actuator type (e.g., contactors, valves,
drives, etc.) that combines actuator control and the necessary auxiliary functions.
Use this actuator block for other actuators of the same type.
Create F-data types for complex actuators.
Auxiliary functions for a safe actuator include, for example:
Feedback circuit monitoring
Error acknowledgment
Edge evaluation
Time functions
Functional switching
Provision of diagnostic information
