Description
Stops data link of the station where an error occurred, and
continues data link only for stations that are operating
normally.
Restarts the data link automatically when the device station
that was disconnected due to an error becomes normal
again.
Continues data link with normally operating stations even if
a cable disconnection or faulty station occurs in a ring
topology network configuration.
If one network has multiple master stations, duplication is
detected.
If one network has stations with the same IP address,
duplication is detected.
This function synchronizes the time of device stations with
the time synchronization source (CPU module of the
master station).
Description
Synchronizes control cycles between device stations over
CC-Link IE TSN according to the inter-module
synchronization cycle specified in the master station. This
allows different device stations on the same network to
operate with the same timing.
Description
Establishes a safety connection and enables one-on-one
safety communications periodically between safety
stations in the same network.
Description
Checks the module hardware when communication using
the RJ71GN11 is unstable.
Monitors the status of CC-Link IE TSN. The network maps,
stations where data link is not operating, selected station
communications status monitor and so on are displayed on
the engineering tool.
Checks if transient transmission data can be properly
routed from the own station to the communication target.
