Function
The IPC_Shutdown instruction starts the shutdown processing of the Industrial PC and, when com-
pleted, notifies Windows of the shutdown request.
Use this instruction when the temporary power interruption signal is received from the UPS or the
power button on the Industrial PC is pressed. Executing this instruction causes the user program to
stop after executing the POU being executed. Perform the shutdown processing on the Controller
before you execute this instruction.
The shutdown processing on the Controller includes the following operations, for example.
• Saving data (variables)
• Stopping the axes of motion controls, moving to the fixed position
• Notifying higher-level management system of a halt
This instruction can be used for shutdown, even when the temporary power interruption signal is not
received from the UPS or the power button on the Industrial PC is not pressed.
If this instruction is used more than once in the project, the shutdown processing will be started when
the first instruction is executed.
