For a variety of complex scenes, two sets of PID parameters have been introduced into
the process PID module. Switching or linear interpolation of the two sets of parameters can
be performed according to the function setting (F09.11) and input conditions (e.g. input
function “43: PID parameter switching”, and deviation e(k)). See the instruction Table 7-13
for details.
Table 7-13 Description of PID Parameter Options
PID parameters are not switched. The first group of
parameters is used.
43: PID parameter
switching
PID parameters are switched via the digital input terminal
(43: PID parameter switching).
Invalid switching, the first group of parameters
Valid switching, the second group of parameters
PID parameters are automatically switched according to
the deviation.
The first group of parameters
The second group of parameters
According to the deviation, linear interpolation is
performed based on the two groups of parameters.
As described in the table, when the function code F09.11 is set to 0, the PID
parameters will not be switched, and the first group of parameters (F09.05 to F09.07) will
