Description (all elements refer to the Function Block instance, replaced for the placeholder $FB$) |
EN |
R/W |
Toggle |
To enable the Function Block with the true value. |
SET_VALUE |
R/W |
Numpad – value 0.0 to 100.0 |
Set value of the process variable in terms of percentage. |
ACTUAL_VALUE |
R/W |
Numpad – value 0.0 to 100.0 |
Actual value of the process variable in terms of percentage. |
KP |
R/W |
Numpad – value 0.0 to 100.0 |
Proportional gain of the PID. |
TN |
R/W |
Numpad – value 0.0 to 100.0 |
Integral time of the PID in terms of seconds. |
TD |
R/W |
Numpad – value 0.0 to 100.0 |
Derivative time of the PID in terms of seconds. |
PID_FREEZE |
R/W |
Toggle |
For the TRUE value the setpoint to the PID block is frozen. Actual value is then attached to the setpoint. |
PID_MAX_LIMIT |
R/W |
Numpad – value 0.0 to 100.0 |
Limit for the maximum PID Output. |
PID_MIN_LIMIT |
R/W |
Numpad – value 0.0 to 100.0 |
Limit for the minimum PID Output. |
PUMP_RUNTIME_RESET |
R/W |
Toggle |
TRUE value of this variable resets the actual runtime to Zero value. |
DONE |
R |
|
Execution finished when output DONE = TRUE. |
ERR |
R |
|
Error occurred during execution when output ERR = TRUE. |
ENO |
R |
|
Error code. |
PID_OUT |
R |
|
PID output after the manipulation in terms of percentage. |
PID_DEVIATION |
R |
|
Deviation of Set value from actual value. It is also known as PID error. |
PID_SPEED_REF |
R |
|
Speed reference as a correction to the main speed reference, calculated by the PID - in the range of 0 to 20000. |
MAX_LIMIT_REACHED |
R |
|
Indicates if the PID output touches the MAXIMUM limit. |
MIN_LIMIT_REACHED |
R |
|
Indicates if the PID output touches the MINIMUM limit. |
