Data Processing Time
This section describes the length of time that lasts from detection by a sensor to data
processing by PLC.
Maximum data processing time = (1) + (2) + (3) + (4)
(1)PLC scan time
(2)RPI (Transmission cycle)
(3)DL-EP1 data communication time
(4)Sensor amplifier response time
(2)RPI is set with the scanner unit. It can be set in 0.5 ms increments between 0.5 ms
and 10000 ms.
(3)DL-EP1 data communication time
The time required for sending outputs and current value data from a sensor
amplifier to the DL-EP1 is as follows:
For details on the PLC scan time in (1) and the sensor amplifier response time in (4),
refer to the manual of each unit.
