Debugging functions
Adjusting and debugging control loops is simple and user-friendly via, for example,
the application-specific loop configuration screen which, in online mode, provides
access to the following functions:
b
Display and animation of the loop algorithm diagram
b
Display of process alarms and channel faults
b
Simulation of the input interface values: For example when these are not connected
(
measurement, Feed Forward)
b
Addition, deletion or replacement of calculation functions in online mode
b
Modification of the adjustment parameters for each of the functions
b
Modification of the controller operating modes and manual control mode
With the controllers integrated in the control loops, it is possible to use the autotuning
function which calculates a set of adjustment parameters (Kp, Ti, Td or Ks, T1, T-delay)
on request.
Once the loop has been debugged, it is possible to save the current values resulting
from the tests in the initial loop parameters values. This means that on restarting the
loop, it will start off with the correct values.
Debugging a loop
The debug screen can be used to:
b
Display the values of the variables linked to the loop in real time
b
Know which parameters have been selected (and even modify them)
b
Display alarms
The menus can be used for manual control of the loop, autotuning, parameter backup,
etc.
Debugging the setpoint programmer
The setpoint programmer channels have their own debug screen which can be used
to display:
b
The number of the active segment and the iteration
b
The execution time for the active segment
b
The overall execution time
