Description
Stores the data reception status of own station channel 8.
Off: No data received
On: Data received
(Conditions)
• This relay is enabled when "Baton pass status of own station" (SB0047) is off.
• When "Baton pass status of own station" (SB0047) is turned on, data prior to error is held.
Stores the network type of the own station.
On: CC-Link IE Field Network
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: Slave station (other than the master station)
On: Master station
Stores the station No. setting status.
Off: Station No. set
On: Station No. not set
If parameters are set using the engineering tool, this relay is always OFF.
Stores the baton pass status (transient transmission availability) of the own station.
Off: Normal
On: Error
When this relay is turned on, the cause of the error can be checked with "Baton pass status of own station"
(SW0047) and "Cause of baton pass interruption" (SW0048).
Depending on the link refresh timing, the update of "Baton pass status of own station" (SW0047) and "Cause
of baton pass interruption" (SW0048) may be offset by one sequence scan.
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.
(Conditions)
• This relay is enabled when "Baton pass status of own station" (SB0047) is off.
• When "Baton pass status of own station" (SB0047) is turned on, data prior to error is held.
Stores the minor error occurrence status of the CPU module on the own station.
Off: No minor error
On: Minor error
Stores the moderate/major error occurrence 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
On: STOP, PAUSE, 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
Stores the acceptance status of "Link startup of own station" (SB0000).
Off: Not accepted (SB0000 is off.)
On: Accepted (SB0000 is on.)
(Conditions)
• This relay is enabled when "Baton pass status of own station" (SB0047) is off.
• When "Baton pass status of own station" (SB0047) is turned on, data prior to error is held.
Stores the status of link startup processing requested with "Link startup of own station" (SB0000).
Off: Link startup not completed (SB0000, SB0050 are off.)
On: Link startup completed (SB0000, SB0050 are on.)
(Conditions)
• This relay is enabled when "Baton pass status of own station" (SB0047) is off.
• When "Baton pass status of own station" (SB0047) is turned on, data prior to error is held.
Stores the acceptance status of "Link stop of own station" (SB0001).
Off: Not accepted (SB0001 is off.)
On: Accepted (SB0001 is on.)
(Conditions)
• This relay is enabled when "Baton pass status of own station" (SB0047) is off.
• When "Baton pass status of own station" (SB0047) is turned on, data prior to error is held.
