FB_BA_ActuatorAnalog
![FB_BA_ActuatorAnalog 1:](Images/png/9007210620417163__Web.png)
The template is used to control analog aggregates. It essentially consists of an AO 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 | 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 analog output object Mdlt. |
Outputs
Name | Type | Description |
---|---|---|
fMdlt | REAL | Current value of the analog 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 | Display of the active priority. |
Inputs CONSTANT
Name | Type | Description |
---|---|---|
Mdlt | Current value of the analog output object. | |
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. |
