Explanation
• Selects whether or not the data is refreshed when the COM
instruction is executed.
• Designation of SD778 is made valid when SM775 turns ON.
b15 b14 to b5 b4 b3 b2
SD778 0
• 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"
• Selects whether or not the data is refreshed when the COM
instruction is executed.
• Designation of SD778 is made valid when SM775 turns ON.
b15 b14 to b5 b4 b3 b2
SD778
0
• 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.
• Selects whether or not the data is refreshed when the COM,
CCOM instruction is executed.
• Designation of SD778 is made valid when SM775 turns ON.
