Fig. 3.16.1 PID SET screen 
      For Channel selection, it is available for IPC5000D. 
   (1) Control Algorithm selection button : It is changeable only at STOP mode. 
z  Button to select PID Control Algorithm. 
z  PID-A : This is three-mode control algorithm(P(Proportional), I(Integral),D(Derivative)) 
          and used for most control field. 
z  PID-B : Unlike the PID A equation, the controller gives only an integral response to a   
setpoint change, with no effect on the output due to the gain or rate action, and   
it gives full response to PV changes. Otherwise controller action is as   
described for the PID A equation.
 
z  DUP-A : PID-A algorithm for Heat/Cool control. 
z  DUP-B : PID-B algorithm for Heat/Cool control. 
 
(2) P-value Set selection button 
z  Selects P (Proportional Band) value type 
   GAIN = 
BP.
%100
 
 
P-BAND is the range indicated by the percentage of process value. 
GAIN
 is the ratio of process value change (%) to output change (%). 
 
(3) Reset value set selection button 
z  Selects the type applied to Reset value. 
z  MIN / RPT: Minutes per Repeat.   
z  RPT / MIN: Repeat per Minutes.
