POINT
The CPU module performs the following in any of RUN, STOP, and PAUSE
status:
• I/O module refresh processing
• Network module refresh processing
• Automatic refresh processing of intelligent function module
• Self-diagnostic processing
• Communication processing with external device such as GX Developer
• Processing of instructions dedicated to intelligent function modules
(completion processing only)
If placed in the STOP or PAUSE status, therefore, the CPU module can perform I/
O monitor and test operation using GX Developer, read/write from/to the external
device using the MC protocol, communication with the other stations on
MELSECNET/H, and communication with CC-Link remote stations.
