executed.
• Designation of SD778 is made valid when SM775 turns ON.

• Refresh between multiple CPUs by COM instruction is performed under
the following occasion.
Receiving operation from other device: b4 of SD778(refresh in the CPU
shared memory) is turned to 1.
Sending operation from host CPU : b15 of SD778(communication with
peripheral device is executed/nonexecuted) is turned to 0.
• Selects whether or not the data is refreshed when the COM instruction is
executed.
• Designation of SD778 is made valid when SM775 turns ON.

SD778
• Refresh between multiple CPUs by COM instruction is performed under
the following occasion.
Receiving operation from other device: b4 of SD778(refresh in the CPU
shared memory) is turned to 1.
Sending operation from host CPU : b15 of SD778(communication with
peripheral device is executed/nonexecuted) is turned to 0.
• When b2 (refresh of the CC-Link IE controller network and
MELSECNET/H) of SD778 is 1, the CC-Link IE controller network and
MELSECNET/H perform refresh.
Therefore, if there are many refresh points, processing time for the COM
instruction will be extended.
