Activating Function Blocks (Activate)
Each safety-related function block can be activated and deactivated via the Activate input.
This means the Activate input can be used to connect/disconnect one or more items of safety equipment and implement modular safety equipment.
If a function block is deactivated (Activate input = FALSE), any state changes and detected edges at its other inputs have no effect on the states of the function block outputs.
| Hinweis
In order to activate a function block perpetually, you can connect its Activate input to the TRUE constant. |
The topic is explained in terms of the following categories:
- Individual activation of safety equipment: Manual connection/disconnection (activation/deactivation) of individual, mutually independent safety-related functions.
- Group activation of safety equipment: Manual connection/disconnection (activation/deactivation) of combined, mutually independent safety-related functions via a common signal.
- Modular machines/systems with safety equipment: Process-related connection/disconnection (activation/deactivation) of individual system modules with safety equipment.
