S_OutControl input
State-controlled input for controlling the contactors connected to the S_EDM_Out function block output. This may, for example, be the enable signal from an EmergencyStop function block of an emergency-stop circuit.
Data type: SAFEBOOL
Initial value: SAFEFALSE
The S_OutControl input controls the S_EDM_Out output signal of the function block, taking the feedback signals at function block inputs EDM1 and EDM2 into consideration.
Connection: Connect this input to a signal (value SAFETRUE or SAFEFALSE); constant SAFETRUE or SAFEFALSE values are not permitted. A typical application, for example, would involve connecting the S_OutControl input to the enable signal of an upstream safety-related function block (e.g., SF_EmergencyStop, SF_TwoHandControlTypeII, etc.).
If the function block is activated (input Activate = TRUE) and the mandatory start-up inhibit has been removed, the possible values at this input lead to the following function block behavior:
| Value | Description |
|---|---|
| SAFETRUE | The upstream safety-related function is not requested.The function block verifies the initial state of the connected contactors via the feedback signals at the EDM1 and EDM2 inputs. If the initial state is ok (EDM1 and EDM2 = TRUE), the function block also outputs a SAFETRUE signal at the S_EDM_Out output.Refer to the warning below this table. |
| SAFEFALSE | The upstream safety-related function is requested. The S_EDM_Out output is switched to SAFEFALSE. |
