(3) Link refresh time
The link refresh time (CPU module end processing time extension) is calculated
as shown below.
• Link device allotment points
• Type of CPU used

1: The total number of points for the range that is actually refreshed.
(Includes unused areas as well)
2: Becomes the total when simultaneous transient transmissions are
performed from multiple stations.
Remote I/O station link refresh time (αr)
The remote I/O station link refresh time (αr) does not affect transmission delay
