(d) Auto refresh with an intelligent function module
This is the time required for refreshing data between the buffer memory of an intelligent function module and
devices in the CPU module.
Use intelligent function module utility package (GX Configurator) for auto refresh settings.
Calculation method
Use the following expression to calculate the auto refresh time with an intelligent function module.
(Refresh time) = KN1 + KN2
For KN1 and KN2, use the values given in Table10.8 and Table10.9.
