Description
Shows the receive status in the communication cycle in which the cyclic data from the slave 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 slave stations is not received consecutively.
• Stations that surpass the maximum station No. are ignored.
(Also used in the CLPA conformance test.)
Stores the link-down status of the own station P1 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.)
Stores the status of parameter reception from the master station.
Off: Reception completed
On: Reception not completed
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 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.
Stores the data link status of the master station (master operating station).
Off: Normal
On: Error
Stores the station type match status of each station.
Off: Station type match in all stations
On: Station type mismatch exists
When this relay is turned on, the status of each station can be checked with 'Station type match status'
(SW00E8 to SW00EF).
Depending on the link refresh timing, the update of 'Station type match status' (SW00E8 to SW00EF) may be
offset by one sequence scan.
Stores the operating status of the CPU module on each station.
Off: All stations are at RUN or STEP-RUN state
On: Station at STOP or PAUSE state, or station with a moderate/major error exists.
When this relay is turned on, the status of each station can be checked with 'CPU operating status of each
station' (SW00F0 to SW00F7).
Depending on the link refresh timing, the update of 'CPU operating status of each station' (SW00F0 to
SW00F7) may be offset by one sequence scan.
Stores the operating status of the CPU module on the master station (master operating station).
Off: RUN
On: STOP state, PAUSE state, or moderate/major error
Stores the moderate/major error occurrence status of each station.
When the target station is master/local module, the occurrence status on the CPU module is stored.
Off: No station with a moderate/major error
On: Station with a moderate/major error exists
When this relay is turned on, the status of each station can be checked with 'CPU moderate/major error status
of each station' (SW0100 to SW0107).
Depending on the link refresh timing, the update of 'CPU moderate/major error status of each station' (SW0100
to SW0107) may be offset by one sequence scan.
Stores the moderate/major error occurrence status of the CPU module on the master station (master operation
station).
Off: No moderate/major error
On: Moderate/major error
Stores the minor error status of the CPU module on the master station.
Off: No minor errors occurring, or a moderate/major error is occurring
On: Minor error
