Parameter 
Data Type  Value Range 
Default 
Description 
CYCLE 
TIME 
>= 1 ms 
T#1s 
SAMPLE TIME. The time between block calls 
has to be constant.  The input  "Sample time" 
indicates the time between block calls. 
SP_INT 
REAL 
-100.0...+100.0% 
0.0 
INTERNAL SETPOINT. The input "Internal 
setpoint" is used to specify the setpoint. 
PV_IN 
REAL 
-100.0...+100.0% 
0.0 
PROCESS VARIABLE IN / Actual value input. 
At the input "Actual value input", a startup 
value can be parameterized, or an external 
actual value can be wired in the floating point 
format.   
PV_PER 
WORD 
 
W#16#0000 
PROCESS VARIABLE PERIPHERy / Actual 
value Periphery. The actual value in the 
periphery format is wired to the controller at 
the input "Actual value Periphery ". 
MAN 
REAL 
-100.0...+100.0% 
0.0 
MANUAL VALUE. The input "Manual value" is 
used to specify a manual value by means of 
the operator interface function. 
GAIN 
REAL 
 
2.0 
PROPORTIONAL GAIN /Proportional 
coefficient.  The input "Proportional 
coefficient" indicates controller gain.  
TI 
TIME 
>= CYCLE 
T#20s 
RESET TIME / Integration time. The input  
"Integration time" determines the time 
response of the integrator. 
TD 
TIME 
>= CYCLE 
T#10s 
DERIVATIVE TIME. The input "Derivative 
time" determines the time response of the 
differentiator. 
TM_LAG TIME  >=CYCLE/2 
T#2s 
TIME LAG OF THE DERIVATE ACTION / 
Delay of the D-component. The algorithm of 
the D-component contains a delay that can be 
parameterized at the input "Time lag of the 
derivative action". 
DEADB_W REAL 
>=0.0 
0.0  DEAD BAND WIDTH. The system deviation   
is taken via a dead band.  The "Dead band 
width" determines the size of the dead band.
