Parametering
The parameter assignments of the function block are satisfied by the determination of the integral gain and the limiting values ymax and ymin for output Y.
The values ymax and ymin limit the output within the prescribed range. Therefore ymin ≤ Y ≤ ymax
If the threshold value is reached or the output signal is limited this will be indicated by qmax and qmin.
Operating mode
There are three operating mode selectable through the man and halt parameter inputs:
Operating mode
man
halt
Meaning
Automatic
0
0
The function block operates as described in "Parametering".
Manual mode
1
0 or 1
The manual value YMAN will be transmitted fixed to the output Y. The control output is, however, limited by ymax and ymin.
Halt
0
1
The output Y will be held at the last calculated value. The output will no longer be changed, but can be overwritten by the user.
Example
The input signal is integrated via the time. If there is a jump on input X the output increases (for positive X values) or decreases (for negative X values) according to a ramp function. Y is always between ymax and ymin; if Y is equal to ymax or ymin, this is shown accordingly in qmax or qmin.
