Remote I/O Communications Performances
Wireless communication cycle time (T
Actually measured reference data
Note For details on the Input I/O Unit input delay time and the Output I/O Unit out-
put delay time, refer to the information in the "DeviceNet Slave Manual"; for
details on the communication cycle and refresh processing time, refer to the
information of the remote I/O communication performance in the "DeviceNet
User’s Manual". Refer to the PLC Operation Manual for details on the PLC
cycle time.
The maximum I/O response time (T MAX) can be obtained from the following
expression:
T
Wireless communication delay time occurs in a wireless network when using
wireless units. The wireless communication delay time becomes longer
depending on the increase in the number of wireless slave stations and relay
stages. The unit is ms.
Use the following values of the I/O response time (IN input -PLC processing -
OUT output) measured by the OMRON system test as reference.
The data described is the smallest and largest values resulting from 30 times
of continuous testing. The actual measurements could be longer than the
largest value depending on the environment where the measurements were
taken. Thus, use the results only as a reference.

OUTSIZE [byte]: Add 1, if an odd number results when even numbers, slave 8-point
output, etc. are used.
INSIZE [byte]: Add 1, if an odd number results when even numbers, slave 8-point
input, etc. are used.
Wireless slave stations for which the Disconnect/Connect Switch is set to
ON (i.e., disconnected) are not included in the total cycle time of wireless
slave stations.
