Description
Stores if a receive frame error line status caution level is currently occurring in the P1 side of the own station.
Off: A receive frame error line status caution level is not occurring.
On: A receive frame error line status caution level is occurring.
Stores if a receive frame error line status caution level is currently occurring in the P2 side of the own station.
Off: A receive frame error line status caution level is not occurring.
On: A receive frame error line status caution level is occurring.
Stores if a receive frame error line status caution level has occurred in the P1 side of the own station from
power-on until the present.
Off: A receive frame error line status caution level has not yet occurred.
On: A receive frame error line status caution level has occurred.
Stores if a receive frame error line status caution level has occurred in the P2 side of the own station from
power-on until the present.
Off: A receive frame error line status caution level has not yet occurred.
On: A receive frame error line status caution level has occurred.
Stores the setting status of line types when the redundant system was configured.
Off: Single Line
On: Redundant Line
The relay turns off for the configuration other than the redundant system.
Stores the operating status of the CPU module on the master operating station.
Off: RUN
On: STOP state, PAUSE state, or moderate/major error
(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 (error), data prior to error is held.
Stores the moderate/major error occurrence status of the CPU module on the master operation station.
*1
Off: No moderate/major error
On: Moderate/major error
(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 (error), data prior to error is held.
Stores the minor error occurrence status of the CPU module on the master operating station.
Off: No minor errors, or a moderate/major error being occurred
On: Minor error
(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 (error), data prior to error is held.
Stores the cycle over occurrence status of the inter-module synchronization function. This relay is turned on
if link scan is not completed within the inter-module synchronization cycle.
Off: Processing time overflow has not occurred.
On: Processing time overflow has occurred.
Once this relay is turned on, it remains turned on even if the processing is operated within the specified
inter-module synchronization cycle. The status is cleared by turning off and on the power supply or resetting
the remote head module.
Stores the redundant system support information of the own station.
Off: Redundant function not supported
On: Redundant function supported
By setting these areas as the refresh target device of the link special relay (SB) of the CC-Link master/local
module, the data link status of CC-Link can be checked.
