Transmission Delay Time - Mitsubishi Electric CC-Link IE TSN User Manual

Transmission delay time

This section describes the transmission delay time of the NZ2GN-GFB.
When the NZ2GN-GFB is used as the CC-Link IE Field Network master station (1)
The following image indicates the transmission delay time for communication between the CC-Link IE TSN master station and
CC-Link IE Field Network intelligent device stations/remote device stations.
