Data Processing Times
This section describes the length of time taken from detection by a sensor(s) to data
processing by PLC.
Maximum data processing time = (1) + (2) + (3) + (4)
(1) PLC scan time
(2) Network scan time
(3) Data communication time of DL-DN1
(4) Response time of sensor amplifier
(3) Data communication time of DL-DN1
The length of time for the data output or current value to be sent from a sensor
amplifier to the DL-DN1 are summarized below.
Sensor amplifier with calculation function OFF, or sensor amplifier with no calcula-
tion function
For information on (1), (2), and (4), refer to the manual of each unit.
