(e) 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.
Calculation method
Calculate using the following formulas. Use the values in the following tables for KN1 and KN2.
(Refresh time) = KN1 + KN2 × (number of refresh points)
When the number of auto refresh points for the analog-digital converter module (Q64AD) is 4 points
(when the module is mounted on the Q26UDHCPU main base unit)
(5) Function execution time in END processing
This is the time required for updating calendar or clearing error in END processing.
(a) Calendar update
The following processing time is required to change or read the clock data when the clock data set request
(SM210 changes from off to on) or the clock data read request (SM213 turns on) is issued.
