Calculation Example
Conditions:
Input ON delay: 1 ms (normal input 0.0 8 to 0.11 with input constant set to 0 ms)
Output ON delay: 0.1 ms (transistor output)
Cycle time: 20 ms
Minimum I/O response time = 1 ms + 20 ms + 0.1 ms = 21.1 ms
Maximum I/O response time = 1 ms + (20 ms × 2) + 0.1 ms = 41.1 ms
Input constant setting can be set in the PLC Setup.
Increasing the input constants slowers the input response time and reduces the effects of chattering
and noise. Decreasing the input constants fasters the input response time and allows reception of
shorter input pulses (but the pulse width must be longer than the cycle time).
