POINT
The values in previous page are calculated on the basis that data are received from
all stations during one sequence scan.
When the link scan is long or when the sequence scan is short, data from all
stations may not be received within one sequence scan.
If this occurs, the actual link refresh time is less than the calculated value shown in
this section.
Remote I/O station link refresh time (r)
The remote I/O station link refresh time (r) does not affect transmission delay
time.
