Description
Stores the link-down status of the own station P2 side.
OFF:Link-up
ON:Link-down
The time until link-up starts after power-on or Ethernet cable connection may vary.
Normally link-up takes several seconds. Depending on device status on the line, link-up
processing is repeated and may increase the time.
(Also used in the CLPA conformance test.)
(Updated even when the station is set to the error invalid station.)
(Updated even when the station is set to the reserved station.)
Stores the status of reserved station specification by parameter. The station number of the
station set as a reserved station can be checked with 'Reserved station setting status'
(SW00C0 to SW00C7).
OFF: Not specified
ON: Specified
Stores the status of error invalid station setting by parameter. The station number of the
station set as an error invalid station can be checked with 'Error invalid station setting
status' (SW00D0 to SW00D7).
OFF: Not specified
ON: Specified
Stores the setting status of "Network Topology" of the own station (master operating
station).
OFF:Line topology, star topology, or coexistence of star and line topologies
ON:Ring topology
Stores the setting status of "Data Link Error Station Setting" under "I/O Maintenance
Settings" in "Supplementary Cyclic Settings" of "Application Settings" for the own station.
OFF: Clear
ON: Hold
Stores the setting status of "Output Hold/Clear Setting during CPU STOP" under "I/O
Maintenance Settings" in "Supplementary Cyclic Settings" of "Application Settings" for the
own station.
OFF: Hold
ON: Clear
Stores the type of IP address.
OFF: IPv4
ON: IPv6
Stores the status of the IP address setting by parameter.
OFF: No setting
ON: Set
Stores the acceptance status of the remote device test function.
OFF: Not accepted
ON: Accepted
Stores the operating status of the remote device test function.
OFF: Not completed
ON: Completed
Stores the data link status of each station.
OFF: All stations normal
ON: Faulty station exists
When this relay is turned on, the status of each station can be checked with 'Data link
status of each station' (SW00B0 to SW00B7).
Depending on the link refresh timing, the update of 'Data link status of each station'
(SW00B0 to SW00B7) may be offset by one sequence scan.
Since a local station cannot obtain the station information of the CC-Link IE TSN Class A
remote station when communicating in multicast mode, "0: Data link normally operating
station" is reflected to the CC-Link IE TSN Class A remote station.
(Condition)
• Reserved stations and stations that surpass the maximum station No. are ignored.
Stores the data link status of the master station.
