Data Link I/O Response Time

Section 8-3

The equation for minimum data link I/O response time is as follows:

Input ON delay	---

Cycle time of PLC at node #1	15 ms

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

Output ON delay	---

Total (data link I/O response time)	35 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.

In case of the CQM1H, however, the cycle time will be incremented by the value obtained from dividing the total number of data link words by the maxi- mum number of words (1,200 words) per time.

For example, if the total number of data link words is 5,000, the result will be as shown below.

5,000/1,200 = 2.5 (approx. 3)

Cycle time of PLC at node #7 ⋅ (1+3)

Noise may increase I/O delays.

Output

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.
