(5) Module refresh time
Module refresh time is the total time for the link refresh of CC-Link IE controller
network or MELSECNET/H and the auto refresh of CC-Link Safety set in the network
parameters.
(a) CC-Link IE controller network refresh time
This is the time required to refresh data between the link devices of the CC-Link
IE controller network module and the devices of the CPU module.
The CC-Link IE controller network refresh time (Tmnet) will be calculated with the
following formula:
Tmnet = 1.85 (number of words to be refreshed) + 1000 (
s)
For the number of words to be refreshed, refer to the following manual.
CC-Link IE Controller Network Reference Manual
(b) MELSECNET/H refresh time
This is the time required to refresh data between the link devices of the
MELSECNET/H module and the devices of the CPU module.
The MELSECNET/H refresh time (Tmnet) will be calculated with the following
formula:
Tmnet = 1.85 (number of words to be refreshed) + 1000 (
s)
For the number of words to be refreshed, refer to the following manual.
Q Corresponding MELSECNET/H Network System Reference Manual
(PLC to PLC network)
(c) CC-Link Safety auto refresh time
This is the time required to refresh data between the CC-Link Safety master
module and the CPU module.
For the CC-Link Safety auto refresh time, refer to the following manual.
CC-Link Safety System Master Module User's Manual
(6) Common processing time
This indicates the processing time common to the CPU modules.
Table10.4 shows the common processing time for each CPU module model.
