Data Link I/O Response Time

Section 8-3

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		8 ms ⋅	2

Communications cycle time ⋅	4	9.9 ms ⋅		4

PLC cycle time at node #7 ⋅	2 (See note.)	8 ms ⋅	2	(See note.)

Output ON delay		15 ms

Total (data link I/O response time)		88.1 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 ⋅ (2+3)

The PLC cycle time when data link words exceed 12,000 using a CS/CJ- series Controller Link Unit with unit version 1.2 or later is calculated as fol- lows.

12,000 to 15,600 (approx.) words: ⋅ 3

15,600 (approx.) to 20,000 words: ⋅ 4

Noise may increase I/O delays.
