Data link I/O response time
The cycle time of the PC at node #7 is 50 ms or 15 ms.
The following diagram illustrates the data flow that will produce the minimum
response time, i.e., the time required if all signals and data transmissions are
processed as soon as they occur.
The equation for minimum data link I/O response time is as follows:
Response time =
input ON delay (0 ms) + cycle time of PC at node #0 (20 ms)
+ communications cycle time (19 ms) × 2 + cycle time of PC at node #7 (50 ms)
+ output ON delay (0 ms)
= 108 ms
