2 Instruction Descriptions
• An error occurs if the value of AIn, CtlPrd, MinPlsWidth, or Delay is outside of the valid range.
Error changes to TRUE and DOut changes to FALSE. If the value of AIn exceeds the valid range,
the operation of DOut will be as shown below depending on when the error is reset.
• If the error is reset after the point where DOut changes to TRUE, the time-proportional output for
DOut is restarted from the next control period.

• If the error is reset before the point where DOut changes to TRUE, the time-proportional output for
DOut is restarted in the control period in which the error was reset.

Version Information
A CPU Unit with unit version 1.02 or later and Sysmac Studio version 1.03 or higher are required
to use this instruction.
Sample Programming
This sample performs temperature control for four points with upper/lower limit alarms and upper/lower
deviation alarms. PID control is performed. The manipulated variables of PID control are converted to
time-proportional output values that are output to heating devices.
