8.15 Controlling with Level PID
Level PID function is used to set the following parameters for control to each divided
level of the input range (up to 8 levels): PID values, Control response parameters and
Output limiter high/low.
Description of function

Set the values such as PID values of each level to the Memory area 1 to 8 (PID
memory group 1 to 8).

The input range can be divided based on the setting for the parameters of Level
PID setting 1 to Level PID setting 7.

The value selected in the Level PID action selection [SV or PV] is checked and
determined in which level of the PID it is, and the control is done using the PID
values from the Memory area appropriate to the level.

Different levels can be set at Input 1 and Input 2.

Memory area to be used for level
The memory area used at each level will be selected after comparison between the
Level PID setting and the value [Set value (SV) or Measured value (PV)] selected in
the Level PID action selection.
