RESPONSE TIME
• Input module
Response time is time from when a step (0 to 100%) input signal is applied to the input module (slave) until when output from its communication CPU reaches 90% of the final value.
LS: Link scan time (CC-Link IE Field communication cycle)
Link scan time depends on the system configuration and settings.

INP
: Input module response time ≤ Input Delay time (Ta) + Conversion rate
*1
(Tb) + input internal processing delay time (Tc) (two link scan time)
*1. Conversion rate x Averaging
E.g.: Averaging (2), input delay time of 20 msec, link scan time of 1 msec.
Input module response time (T
INP
): Input Delay time (20 msec.) + Conversion rate (0.5 msec.) × Averaging (2)
+ internal processing delay time (1 msec. x 2) = 23 [msec.]
