Link Servicing Interval (Source and Destination Nodes)
Link service processing is the same as the PLC’s peripheral servicing and is
approximately 1 ms for Controller Link Units.
Transmission Processing
Commands: 2 ms
Responses: Number of words transferred × 0.00125 ms + 3 ms
Communications Cycle Time (with Data Links Inactive)
See 8-2 Communications Cycle Time (on page 255).
Transmission Delay Time
Transmission delay time varies with the baud rate.

Responses: Transmission delay time is calculated according to the number of
words to be transferred.
