You can use the RUN output for the following purposes:
• Obtain a signal to notify the host that the CPU Unit is functioning normally and is currently operating.
• Synchronize the completion of startup of more than one CPU Unit
• Release interlocks when the CPU Unit starts operation.
Precautions for Safe Use
It takes up to approximately 10 to 20 s to enter RUN mode after the power is turned ON. The out-
