CC-Link IE TSN master/local module

Control communication requiring real-time performance and TCP/IP communication can be mixed, maximizing CC-Link IE TSN performance and functionality.

RJ71GN11-T2

Deterministic performance of cyclic communication is maintained even when mixed with slower information data (non real-time)
TCP/IP communication devices can be used without affecting overall control

Some devices cannot be connected to CC-Link IE TSN depending on the system configuration.

*1.Class B managed Ethernet switch supporting CC-Link IE TSN recommended by the CC-Link Partner Association

Highly accurate time synchronization accuracy within ±1 µs and each station connected to the network sharing time-stamp information in 1 ms increments improves system diagnostics and troubleshooting by enabling sequential analysis of stations in the network
The error history is displayed consecutively based on time-stamp data, enabling accurate analysis of the cause of error using the actual time the event occurred

The advanced protocol built into CC-Link IE TSN is complemented by the time-sharing method functionality that enables simultaneous communications between network stations
Fast communication cycle time of just 31.25 µs^*2 and high-speed processing approximately 16 times faster than current network performance are achieved, resulting in high-speed and high-accuracy motion control
Productivity is simultaneously improved owing to a substantial increase in control performance, which reduces overall operating time and enables high-speed and large capacity data communication

*2.This value is achieved when fast operation mode of the motion module (RD78GH) is used. Click here for details on MELSEC iQ-R Motion Module User's Manual (Application)
