Description
•
When W0.00 turns ON, the work area in D111 to D140 is initialized (cleared) according to the
parameters set in D100 to D110. After the work area has been initialized, autotuning is started
and the PID constants are calculated from the results from changing the manipulated variable.
After autotuning has been completed, PID control is executed according to the calculated PID
constants set in D101 to D10
3
. The manipulated variable is output to D200. The manipulated vari-
able in D200 is divided by the manipulated variable range using the TPO instruction. This value is
treated as the duty factor which is converted to a time-proportional output and output to
CIO100.00 as a pulse output.
•
When W0.00 turns OFF, PID is stopped and CIO100.00 turns OFF.
•
When W0.00 is ON, the Thermocouple
’
s PV (-200 to 1
3
00) is scaled to the PIDAT instruction input
range (#0 to #1FFF hex). The set values must be input according to the scaled PV. For example, if
the PV is 160°C, it is set as [
8
191/(1
3
00+200)] × (160+200) = 1966].
