Appendix 3 List of Link Special Relay (SB)
Description
Stores the data reception status of own station channel 8.
OFF: No data received
ON: Data received
Stores the network type of the own station.
ON: CC-Link IE TSN
Stores the module operation mode of the own station.
OFF: Online mode
ON: Other than online mode
Stores the station type of the own station.
OFF: Device station (other than the master station)
ON: Master station
Stores the communication mode of the own station.
OFF: Unicast mode
ON: Multicast mode
Stores the station No. setting status.
OFF: Station No. set
Stores the data link error status of the own station.
OFF: Normal
ON: Error
When this relay is turned on, the cause of the error can be checked with 'Cause of data
link stop' (SW0049). Depending on the link refresh timing, the update of 'Cause of data
link stop' (SW0049) may be offset by one sequence scan.
(Also used in the CLPA conformance test.)
(Updated even when the station is set to the error invalid station.)
Stores the minor error status of the CPU module on the own station.
OFF: No minor error
ON: Minor error
Stores the moderate/major error status of the CPU module on the own station.
OFF: No moderate/major error
ON: Moderate/major error
Stores the operating status of the CPU module on the own station.
OFF: RUN, PAUSE
ON: STOP or moderate/major error
Stores the status of received parameter. (For the master station, this relay stores the
parameter status of the own station)
OFF: Normal
ON: Error
Shows the receive status in the communication cycle in which the cyclic data from the
device station is set using "Disconnection Detection Setting" in the master station.
OFF: Cyclic data received
ON: Cyclic data not received consecutively
(Conditions)
• Turns on when the cyclic data of one or more device stations is not received
consecutively.
• Reserved stations and stations that surpass the maximum station No. are ignored.
(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 link down status of the own station at the PORT1 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.)
