Delay Time Of Reception Data - Panasonic FP7 User Manual

10.4 Delay Time of Reception Data

When data sent to the FP7 from an adapter device is received, a delay occurs in the adapter
device and FP7.
 Delay time of adapter devices
The delay time of an adapter device is the total of the delays caused by input processing and
transmission processing.
Delay time of adapter = Delay by input processing + Delay by transmission processing
* The delay time of adapter device varies depending on devices.
Refer to manuals of adapter devices.
 Delay time of FP7 (scanner)
A delay caused by the transmission cycle of an adapter device and the FP7 refresh timing
occurs.
The delay time on the FP7 side depends on the scan time of the FP7 and the RPI value of the
EtherNet/IP communication.
