InOut:

Scope	Name	Type	Initial	Comment
Input	`Activate`	`BOOL`	FALSE	Activation of the FB.
	`S_PSE_In`	`BOOL`	FALSE	Safety demand input. FALSE: PSE actuated, demand for safety- related response, TRUE: PSE not actuated, no demand for safety-related response.
	`S_StartReset`	`BOOL`	FALSE	Start behaviour of safety FB
	`S_AutoReset`	`BOOL`	FALSE	Behaviour on error of safety FB
	`Reset`	`BOOL`	FALSE	Manual reset of FB
Output	`Ready`	`BOOL`	FALSE	Activation of the FB. TRUE indicates that the FB is activated and the outputs results are valid, FALSE the FB is not active and the program is not executed.
	`S_PSE_Out`	`BOOL`	FALSE	Output for the safety-related response. FALSE: Safety output disabled, demand for safety-related response, TRUE: Safety output enabled, no demand for safety-related response.
	`SafetyDemand`	`BOOL`	FALSE	Output indicating that the FB is active and the primary safety function is demanded (e.g. related to the safety functionality).
	`ResetRequest`	`BOOL`	FALSE	Output which can be used to signal the operator to press the reset functionality to continue.
