P1012 – PID Feedback
Adjustable
Range:
0.0 to 3000.0
Factory
Setting:
-
Properties:
ro
Access Groups
via HMI:
SPLC
Description:
Read only parameter that presents, in the wxy.z form without engineering unit, the feedback
value or the process variable of the PID regulator according to the scale defined at P1018.
P1013 – PID Output
Adjustable
Range:
0.0 to 100.0 %
Factory
Setting:
-
Properties:
ro
Access Groups
via HMI:
SPLC
Description:
Read only parameter that presents, in percentage (%), the PID regulator output value.
P1016 – PID Setpoint Selection
Adjustable
Range:
0 = HMI
1 = AIx
2 = Serial/USB
3 = CO/DN/DP
Factory
Setting:
0
Properties:
ro
Access Groups
via HMI:
SPLC
Description:
Defines the source of the PID regulator setpoint.
Notes:
“HMI” means that the PID regulator setpoint will be the value of P1025 parameter.
“AI” means that the PID regulator setpoint will come from an analog input. It is necessary
to set P0231 (AI1) or P0236 (AI2) to 5 = Function 1 of the Application in order to enable its
operation. The following alarm message will be displayed in case it is not properly done:
“A770: Set AI1 or AI2 for Function 1 of the Application”.
“Serial/USB” means that the setpoint of the PID will be the value of P0683 proportionally
referenced to the percentage value with one decimal point, i.e., 100.0 % corresponds to
1000 in P0683.
