7 APPLICATION INSTRUCTIONS
7.27 Module Access Instructions
• Select execution or non-execution for b0 to b4, b6, b13, and b15 of SD775 (Selection of refresh processing during the COM
instruction execution), and then turn on SM775.
• When executed, the COM(P) instruction performs the specified refresh processing.
• In the following program example, link refresh of the CC-Link IE Field Network module is executed when M0 turns on.
Precautions
• The COM(P) instruction can be used as many times as needed in the program. Note, however, that the scan time of the
program is extended by the time of the processing selected by SD775.
• Interrupts are enabled during execution of the COM(P) instruction. If refresh data is used by an interrupt program, data
inconsistency may occur.
• If device/label access service processing is performed by the COM(P) instruction while an Ethernet device is connected to
the Ethernet port, the processing time of the instruction may be extended.
The COM(P) instruction cannot be used in the interrupt program.
Operation error
There is no operation error.
