Refresh processing time
The refresh processing time [s] is a constituent of the scan time of the CPU module. For details on the scan time, refer to the
following.
MELSEC iQ-R CPU Module User's Manual (Application)
The refresh processing time [s], which is taken for refresh, is given by:
• Refresh processing time [s] = Refresh read time (time for transferring refresh data to the CPU module) + Refresh write
time (time for transferring refresh data to the intelligent function module)
The refresh read time and refresh write time vary depending on the settings of "Target".
When "Target" is a refresh data register (RD)
The following table shows the refresh read time and refresh write time with a MELSEC iQ-R series CPU module used.
