CommandVariable (FB)¶

FUNCTION_BLOCK CommandVariable

Command variable

This function block provides a transformation of an input (command) variable to an output range. Underflow / overflow of input can be transformed into separate output value (instead of clipping to end of output range).

InOut:

Scope	Name	Type	Initial	Comment
Input	rIn	REAL		Input value
	rInMin	REAL		Minimum input value
	rInMax	REAL		Maximum input value
	rOutMin	REAL		Corresponding minimum output value
	rOutMax	REAL		Corresponding maximum output value
	rOutUnderflow	REAL		Optional output value for rIn underflow
	xOutUnderflow	BOOL	FALSE	Enable rOutUnderflow
	rOutOverflow	REAL		Optional output value for rIn overflow
	xOutOverflow	BOOL	FALSE	Enable rOutOverflow
Output	rOut	REAL		Output value
