RAMP_REAL (FB)¶

FUNCTION_BLOCK RAMP_REAL

Limits the slope of a value to a certain value

The function block is similar to RAMP_INT with the difference that the inputs IN, ASCEND, DESCEND and the output OUT are of the type REAL. RAMP_REAL takes more computing time but calculates more precisely than RAMP_INT.

Note

A reset of the function block ( RESET = TRUE) stops the calculation and the last output value OUT is maintained. So if afterwards the ramp gets restarted by RESET = FALSE, it will start with this last output value!

InOut:

Scope	Name	Type	Comment
Input	`IN`	`REAL`	Input value
	`ASCEND`	`REAL`	Maximum positive slope
	`DESCEND`	`REAL`	Maximum negative slope (non-negative!)
	`TIMEBASE`	`TIME`	Reference for `ASCEND/DESCEND` : `t#0s`: `ASCEND/DESCEND` defined per call Else : `ASCEND/DESCEND` defined per specified time
	`RESET`	`BOOL`	Resets the function block
Output	`OUT`	`REAL`	Fnction value with limited slope
