Code Modbus ID Parameter Application RO/RW
P7.1.7 1302 PID1 Process Unit Decimal 2,3 RW
This parameter is used to defines the amount of decimal places used in the value for the
PID Controller setpoint.
P7.1.8 1303 PID1 Error Inversion 2,3 RW
This parameter defines the way the process value output reacts to the feedback signal.
0 = Normal, If feedback is less than set-point, PID controller output increases.
1 = Inverted, If feedback is less than set-point, PID controller output decreases.
P7.1.9 1304 PID1 Dead Band 2,3 RW
This parameter sets the PID Dead band around the set point in process units. This is a band where no
actions occur to the ouput of the PID controller, to prevent oscillation or repeated activation/deactivation
of controller.
P7.1.10 1306 PID1 Dead Band Delay 2,3 RW
This parameter sets the delay time, if the PID process value goes out of the Dead Band area for the
desired time delay at that point the controller will re-initialize and try to level out again.
P7.1.11 1311 PID1 Ramp Time 2,3 RW
This parameter defines the rising and falling ramp times for changes in the process value setpoint. The
ramp time corresponds to the time it takes to change the setpoint vlaue from minimum to the maximum,
if the value is 0 no ramps are used.
P7.2.1 2542 FB PID1 Set Point 1 2,3 RW
PID Set point value from Network. Can be assigned to PID Set Point Source
P7.2.2 2544 FB PID1 Set Point 2 2,3 RW
PID Set point value from Network. Can be assigned to PID Set Point Source
P7.2.3 2550 FB PID1 Feedback 1 2,3 RW
PID Feedback value from Network. Can be assigned to PID Feedback Source
P7.2.4 2551 FB PID1 Feedback 2 2,3 RW
PID Feedback value from Network. Can be assigned to PID Feedback Source
P7.2.5 2554 FB PID1 Feedforward 1 2,3 RW
PID Feedforward value from Network. Can be assigned to PID Feedforward Source
P7.2.6 2555 FB PID1 Feedforward 2 2,3 RW
PID Feedforward value from Network. Can be assigned to PID Feedforward Source
P7.3.1.1 1307 PID1 Keypad Set Point 1 2,3 RW
This parameter sets the Keypad PID Reference value set point 1.
P7.3.1.2 1309 PID1 Keypad Set Point 2 2,3 RW
This parameter sets the Keypad PID Reference value set point 2.
P7.3.1.3 2466 PID1 Wake Up Action 2,3 RW
Use this parameter to define the wakeup function action. This defines if a static absolute value is used
above or bleow the level setting or a relative value that chagnes based off the set point value.
0 - Wakeup when below wakeup level (Absolute Level)
1 - Wakeup when above wakeup level (Absolute Level)
2 - Wakeup when below wakeup level % from PID set point (Relative setpoint)
3 - Wakeup when above wakeup level % from PID set point (Relative setpoint)
P7.3.2.1 1312 PID1 Set Point 1 Source 2,3 RW
Use this parameter to define the source of the PID set point value. This can either be an internal preset
value, keypad set point, analog signal or Fieldbus message.
P7.3.2.2 1313 PID1 Set Point 1 Min 2,3 RW
Use this parmaeter to set the minimum value for the set point 1 source.
P7.3.2.3 1314 PID1 Set Point 1 Max 2,3 RW
Use this parameter to set the maximum value for the set point 1 source.
