This sample assumes that a touch panel is connected to the Controller. The following I/O information is
handled through the touch panel.

Converting the Manipulated Variables to Time-proportional Outputs
In this sample, a digital ON/OFF output is used for both the heating device and the cooling device.
Therefore, it is necessary to convert the manipulated variables for the heating and cooling devices to
time-proportional outputs. The TimeProportionalOut instruction (page 2-727) converts a manipulated
variable to a time-proportional output.
However, during autotuning, the outputs to the heating and cooling devices must be changed immedi-
ately after the MV_Heat and MV_Cool outputs from the PIDAT_HeatCool instruction change. There-
fore, the TimeProportionalOut instruction cannot be used. If the TimeProportionalOut instruction was
used, the outputs to the heating and cooling devices would change only at the control period that was
set by the user. In this sample, timer instructions are used to convert the manipulated variables to time-
proportional outputs during autotuning.
