8.6 Response time for the controller input signal
Response delay due to the controller input signal contains following factors.
(1)Controller input signal scan delay
(2)Delay due to input signal analysis
(3)Delay of command analysis
Process delay of PLC or scanning delay of the controller may occur. Keep the input signal
combination for 15ms or longer (the recommendation is 30ms). Initialize the input signal conditioning
the response signal to the input signal.
When one command is made by inputting several I/O simultaneously, time difference between signals
has to be 3ms or less. If the time difference is longer than 3ms, it is recognized as another signal and
start the operation. For example, when IN0 and IN1 are commanded to move to ON(position number
3) simultaneously and the time difference between them is large, only the first command is recognized
(Only IN0 input is recognized).
