Data Link I/O Response Time

Section 9-3

CVM1 and CV-series PLCs Under Asynchronous Operation

Maximum Data Link I/O Response Time

There are five points shown in the diagram above where processing is
delayed, increasing the data link I/O response time.

1,2,3...

1.

The input arrives in the PLC just after I/O refreshing, causing a delay of up
to one cycle before the input is read into the PLC.

2.

Data exchange occurs just after the PLC at node #1 passes the token that
makes it the polling node, causing a delay of up to one communications cy-
cle time before the data is transferred in data link processing.

3.

At node #1, data from the previous data exchange is still being transferred,
causing a delay of up to one cycle before the input is read into the PLC.

4.

The data transferred in data link processing arrives at the PLC at node #7
after data exchange, so the data will not be read into the PLC until the next
data exchange, causing a delay of up to one peripheral servicing interval.

Up to 3,700 words can be transferred in a single data exchange, so a delay
of another peripheral servicing interval will occur if more than 3,700 words
are being transferred.

5.

The data is received after the PLC at node #7 has executed the instruction,
causing a delay of up to one cycle time.

Assume that the peripheral servicing interval of the PLCs at nodes #1 and #7
is 10 ms. The equation for the maximum data link I/O response time is as fol-
lows:
