(4) CPU module operation processing by switch operation
* 1: Since the Basic model QCPU cannot execute multiple programs, it cannot use subroutine
programs in the other programs.
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)
• Operation processing of Multiple CPU high speed transmission function
(Universal model QCPU only)
Even if the CPU module is in STOP or PAUSE status, the following operations can
be executed.
• I/O monitor or test operation using GX Developer
• Read/write from/to the external device using the MC protocol
• Communication with other stations using CC-Link IE controller network
and MELSECNET/H
• Communication with CC-Link remote stations
