Appendix 9 Processing Time
Multiple CPU refresh processing time
This section describes the Multiple CPU refresh processing time.
Refresh processing time [s] = Send refresh time + Receive refresh time
Send refresh time [s] = KM1 + KM2  Number of points of send word
Receive refresh time [s] = KM3 + KM4  Number of other CPU modules + KM5  Number of points of receive word
■Refresh (when END)
The following table lists the constant values when refresh is executed in END processing at CPU buffer memory area.
■Refresh (when I45 is executed)
The following table lists the constant values when refresh is executed in Multiple CPU synchronous interrupt (I45) at fixed
scan communication area.
