State-controlled input for activating the function block.
Data type: BOOL
Initial value: FALSE
Connection: With TRUE constant or TRUE/FALSE input signal.
Connecting the Activate input to an input signal makes it possible to switch off specific safety-related functions in a targeted manner (e.g., individual areas of machines and systems with a modular construction).
The function block is deactivated when Activate = FALSE. Deactivated function blocks switch their outputs to the defined safe state. S_EnableSwitchOut = SAFEFALSE and Error = FALSE signals that no error has been detected.
Application examples and information on how to carry out individual deactivation, group deactivation or how to set up modular safety equipment using function block activation can be found in "Activating function blocks".
Value |
Description |
---|---|
TRUE |
The function block is activated, the inputs are evaluated, and the outputs switched accordingly.
NOTE:
S_AutoReset = SAFEFALSE specifies a restart inhibit which becomes active after a valid signal combination has been returned at inputs S_EnableSwitchCh1 and S_EnableSwitchCh2. The restart inhibit is removed by a FALSE > TRUE edge at the Reset input. Once the restart inhibit has been removed, the status at the S_EnableSwitchOut output can immediately switch from SAFEFALSE to SAFETRUE (depending on the other input signals). Refer to the hazard message below this table. |
FALSE |
The function block is not activated. The S_EnableSwitchOut output is switched to SAFEFALSE. |
