I/O response time
Maximum I/O response time = input ON delay + (cycle time x 2) + overseeing
time + output ON delay
The data in the following table would produce the minimum and maximum
cycle times shown calculated below.
Input ON-delay
Cycle time
Input refresh time
Overseeing time
Output ON-delay
Minimum I/O response time = 1.5 + 20 + 0.23 + 3.0 +15 = 39.73 ms
Maximum I/O response time = 1.5 + (20 x 2) + 3.0 +15 = 59.5 ms
