Intelligent function module refresh processing time
The following calculation formula shows the refresh processing time for the intelligent function module mounted on the main
base unit and the extension base unit.
The refresh processing time described in this manual is for the case when the "Target" is set to "Device" in the
refresh setting. For the refresh processing time of when the refreshing target is set to the module label or
refresh data register (RD), refer to the manual for the module used.
Refresh processing time of one module [s] = Read refresh time
*1 When the number of settings of read refresh (Module  CPU module) or write refresh (CPU module  Module) is 0, each processing
time is 0.
■Read refresh time [s]
Number of read refresh settings  KM1 + Refresh time for the first item (A) + Refresh time for the second item (A) +  +
Refresh time for the nth item (A) + KM2
■Write refresh time [s]
Number of write refresh settings  KM4 + Refresh time for the first item (B) + Refresh time for the second item (B) +  +
Refresh time for the nth item (B) + KM5
• A: KM3  Number of refresh transfer (word) [s]
• B: KM6  Number of refresh transfer (word) [s]
• n: Number of blocks for refresh settings
• KM1 to KM6: Constant value as shown below
Condition
MELSEC iQ-R series module
Q series module
*1 The number of blocks for refresh settings can be checked in "Auto Refresh Setting Total Counts" of "Module Parameter List" window. For
details, refer to the manual for the module used.
