Link service interval (destination mode)

Link service processing (destination node)

Maximum transmission delay

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 Interval (Source and Destination Nodes)

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 (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 ⋅ 0.00075 ms + 2 ms

Communications Cycle Time (with Data Links Inactive

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

Transmission Delay Time

Transmission delay time varies with the baud rate.

Baud rate	Transmission delay time
2 Mbps	Number of words transferred ⋅	0.08 + 0.112 ms
1 Mbps	Number of words transferred ⋅	0.016 + 0.224 ms
500 Kbps	Number of words transferred ⋅	0.032 + 0.448 ms

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.
