Max. transmission delay = Link servicing interval (source node) + Link service
processing (source node) + Transmission processing (command) + Communi-
cations cycle + Transmission delay (command) + Reception processing (com-
mand) + Link servicing interval (destination node) + Link service processing
(destination node) + Transmission processing (response) + Communications
cycle + Transmission delay (response) + Reception processing (response) +
Link servicing interval (source node) + Link service processing (source node).

Link servicing depends on the execution mode of the PLC. The execution
modes on the source and destination modes need not be the same.

For synchronous execution, links are serviced once per PLC execution cycle.
For asynchronous execution, links are serviced according to the peripheral
servicing interval. Refer to the CVM1 and CV-series PLCs Operation Manual:
Ladder Diagrams (W202) for details.

Link service processing is the same as the PLC’s peripheral servicing and is
approximately 1 ms for Controller Link Units.

See 8-2 Communications Cycle Time (on page 251).

Transmission delay time varies with the baud rate.

Note Commands: Transmission delay time is calculated assuming that the number

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