SF_ModeSelector (FB)¶

FUNCTION_BLOCK SF_ModeSelector

This function block selects the system operation mode, such as manual, automatic, semi-automatic, etc.

InOut:

Scope	Name	Type	Initial	Comment
Input	`Activate`	`BOOL`	FALSE	Activation of the FB.
	`S_Mode0`	`BOOL`	FALSE	Input X (0 - 7) from mode selector switch. FALSE: Mode X is not requested by operator. TRUE: Mode X is requested by operator.
	`S_Mode1`	`BOOL`	FALSE
	`S_Mode2`	`BOOL`	FALSE
	`S_Mode3`	`BOOL`	FALSE
	`S_Mode4`	`BOOL`	FALSE
	`S_Mode5`	`BOOL`	FALSE
	`S_Mode6`	`BOOL`	FALSE
	`S_Mode7`	`BOOL`	FALSE
	`S_Unlock`	`BOOL`	FALSE	Locks the selected mode. FALSE: The actual S_ModeXSel output is locked therefore a change of any S_ModeX input does not lead to a change in the S_ModeXSel output even in the event of a rising edge of Set-Mode. TRUE: The selected S_ModeXSel is not locked; a mode selec-tion change is possible.
	`S_SetMode`	`BOOL`	FALSE	Sets the selected mode. Operator acknowledges the setting of a mode. Any change to new S_ModeX = TRUE leads to S_AnyModeSel/S_ModeXSel = FALSE, only a rising SetMode trigger then leads to new S_ModeXSel = TRUE.
	`AutoSetMode`	`BOOL`	FALSE	Parameterizes the acknowledgement mode FALSE: A change in mode must be acknowledged by the operator via SetMode. TRUE: A valid change of the S_ModeX input to another S_ModeX automatically leads to a change in S_ModeXSel with-out operator acknowledgment via SetMode (as long as this is not locked by S_Unlock).
	`ModeMonitorTime`	`TIME`	TIME#0ms	Maximum permissible time for changing the selection input.
	`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_Mode0Sel`	`BOOL`	FALSE	Indicates that mode X (0 - 7) is selected and acknowledged. FALSE: Mode X is not selected or not active. TRUE: Mode X is selected and active.
	`S_Mode1Sel`	`BOOL`	FALSE
	`S_Mode2Sel`	`BOOL`	FALSE
	`S_Mode3Sel`	`BOOL`	FALSE
	`S_Mode4Sel`	`BOOL`	FALSE
	`S_Mode5Sel`	`BOOL`	FALSE
	`S_Mode6Sel`	`BOOL`	FALSE
	`S_Mode7Sel`	`BOOL`	FALSE
	`S_AnyModeSel`	`BOOL`	FALSE	Indicates that any of the 8 modes is selected and acknowledged. FALSE: No S_ModeX is selected. TRUE: One of the 8 S_ModeX is selected and active.
	`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	Error flag Output which can be used to signal the operator to press the reset functionality to continue.
	`Error`	`BOOL`	FALSE	Error flag
	`DiagCode`	`WORD`	0	Diagnostic register
