Processing details
• The COM(P) instructions are used to perform processing such as I/O refresh at any time during execution of the sequence
program.
• The processing performed by the COM(P) instruction includes the following.
• I/O refresh
• Link refresh of the CC-Link module
• Link refresh of the CC-Link IE Controller Network module
• Link refresh of the CC-Link IE Field Network module
• Link refresh of CC-Link IE Field Network Basic
• Link refresh of the MELSECNET/H module
• Intelligent function module refresh
• Refresh of multiple CPU system using the CPU buffer memory (in END processing)
• Import of input/output outside the group of multiple CPU system
• Device/label access service processing (communication with the engineering tool, GOT, or other external devices)
*1 Programmable controller CPU with firmware version "25" or later supports this processing.
• When SM775 is turned off, every processing except I/O refresh is performed.
