4.17 Parameters: 18-** Data Readouts 2

18-90 Process PID Error
Range: Function:
0 % [-200 - 200 %] Give the present error value used by the
*
process PID controller.
18-91 Process PID Output
Range: Function:
0 % [-200 - 200 %] Give the present raw output value from
*
the process PID controller.
18-92 Process PID Clamped Output
Range: Function:
0 % [-200 - 200 %] Give the present output value from the
*
process PID controller after the clamp
limits have been observed.
18-93 Process PID Gain Scaled Output
Range: Function:
0 % [-200 - Give the present output value from the
*
200 %] process PID controller after the clamp
limits have been observed, and the
resulting value has been gain scaled.
