• Selects whether or not the data is refreshed when the
COM instruction is executed.
• Designation of SD778 is made valid when SM775 turns
ON.
• Refresh between multiple CPUs by the COM instruction
is performed under the following conditions.
Data reception from another CPU: When b4 of SD778 is
"1"
Data transmission from host CPU: When b15 of SD778 is
"0"

• Select whether or not each processing is performed
when the COM instruction is executed.
• Designation of SD778 is made valid when SM775 turns
ON.
• Refresh between multiple CPUs by the COM instruction
is performed under the following conditions.
Data reception from another CPU: When b4 of SD778 is
"1"
Data transmission from host CPU: When b15 of SD778 is
"0"
• When b2 of SD778 is 1, both the CC-Link IE Controller
Network and MELSECNET/H perform a refresh.
Therefore, when refresh point is large, processing time
for the COM instruction is extended.
