SEND(90)

The following diagram indicates the data flow which will yield the maximum

delay time from the time SEND(90) is executed by the user program to the

time the Controller Link Unit stores the data in the destination Unit’s memory.

Max. transmission delay

Data stored

Max. transmission delay = Link Unit servicing interval (source node) + Trans- mission processing + Communications cycle time + Transmission delay + Reception processing + Link Unit servicing interval (destination node).

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

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 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

Reception Processing
Responses:		Number of words transferred ⋅ 0.00125 ms + 2.3 ms

Note The I/O response time can increase due to noise or restrictions on the number of frames that can be transmitted while the data link is operating.
