Data Link I/O Response Time

Section 8-3

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 #7, 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 maximum data link I/O response time is as follows:

Input ON delay	1.5 ms

Cycle time of PLC at node #1 ⋅ 2	15 ms ⋅	2

Peripheral servicing interval of PLC at	10 ms
node #1

Communications cycle time ⋅ 3	9.9 ms ⋅	3

Peripheral servicing interval of PLC at	10 ms ⋅	2
node #7 ⋅ 2

PLC cycle time at node #7 ⋅ 2 (See note.)	20 ms ⋅	2 (See note.)

Output ON delay	15 ms

Total (data link I/O response time)	146.2 ms

Note If the total number of data link words is greater than the maximum number of words that can be exchanged per data exchange, the maximum data link I/O response time will be cycle time of PLC at node #7 ⋅ 3.

Noise may increase I/O delays.
