FB_BA_ActuatorMO

The template is used to control multi-stage aggregates. It essentially consists of an MO object for controlling an aggregate and the function block PlantLock, which collects all safety-relevant faults.

	The initialization of the template takes place within the method FB_Init.

Inputs

Name	Type	Description
stCmd	ST_BA_Multistate	The enables and switching values are transmitted to the template via the command structure stCmd . The command with the highest priority is output at the multistate output object Cmd.

Outputs

Name	Type	Description
nCmd	UDINT	Current switch value of the multistate output object.
bDst	BOOL	The variable is an evaluation of the lock priorities "Safety" and "Critical" of the project structure and indicates a triggered event.
eActivePrio	E_BA_Priority	Display of the active priority.

Inputs CONSTANT

Name	Type	Description
Cmd	FB_BA_MO	The multistate output object is used to output the current switch value.
PlantLock	FB_BA_PlantLock	The function block PlantLock collects all safety-relevant faults at this level of the project structure and triggers switching commands in the template accordingly.

Variables

Name	Type	Description
bPrioSfty	BOOL	The variable is an evaluation of the "Safety" lock priority of the project structure.
bPrioCrit	BOOL	The variable is an evaluation of the "Critical" lock priority of the project structure.
