5.4 Delay Time of Communication Data
5-9
5.4.2 Delay Time of Reception Data
When the FP0H receives the data sent from a destination device in the cyclic communication,
each delay time of the destination device and FP0H should be considered.

Delay on the destination device side
The delay time of a destination device is the total of the delays caused by input processing
and transmission processing.
Delay time of destination device = Delay by input proc Delay by transmission
processing
* The delay time on the destination device side varies depending on devices. Refer to
respective manuals of destination devices.

Delay on the FP0H side
A delay caused by the transmission cycle of destination device and the FP0H refresh timing
occurs.
The delay time on the FP0H side depends on the scan time of the FP0H and the RPI value of
the EtherNet/IP communication.
Pattern Relation between scan time and RPI Delay time
1 Scan time is smaller than RPI Scan time
2 Scan time is nearly equal to RPI Scan time (RPI) x 2
3 Scan time is larger than RPI RPI
