Refresh time
Refresh time is the total time required for the CPU module to refresh data with the network such as CC-Link IE,
MELSECNET/H, and CC-Link.
(a) Refresh with CC-Link IE
This is the time required for refreshing data between link devices in a CC-Link IE module and devices in the
CPU module.
(b) Refresh with MELSECNET/H
This is the time required for refreshing data between link devices in a MELSECNET/H module and devices in
the CPU module.
(c) Auto refresh with CC-Link
This is the time required for refreshing data between a CC-Link system master/local module and the CPU
module.
Remark
For each refresh time, refer to the following.
