FB_BA_Dmp2P
The template is for the control of a two-point damper with integrated monitoring of both end positions.
It essentially consists of the base class FB_BA_ActuatorCmd for controlling a binary aggregate and collecting all safety-related faults. The two templates MonitOpn and MonitCls are used to monitor the end positions.
 | The initialization of the template takes place within the method FB_Init. |
