Description
Stores the status of the own station.
No value is stored for offline mode.
01H: STOP (normal)
02H: STOP (moderate/major error)
03H: STOP (minor error)
04H: RUN (normal)
05H: RUN (minor error)
0FH: Initial processing
Stores the network number set in the CC-Link IE Field Network diagnostics.
Range: 1 to 239, 65535 (not set)
Stores the station number set in the CC-Link IE Field Network diagnostics.
Range: 1 to 120, 65535 (not set)
Stores the connection status of the own station.
00H: Normal (communication in progress on P1 and P2)
01H: Normal (communication in progress on P1, cable disconnected on P2)
04H: Normal (loopback communication in progress on P1, cable disconnected on P2)
10H: Normal (cable disconnected on P1, communication in progress on P2)
11H: Disconnecting (cable disconnected on P1 and P2)
12H: Disconnecting (cable disconnected on P1, establishing line on P2)
21H: Disconnecting (establishing line on P1, cable disconnected on P2)
22H: Disconnecting (establishing line on P1 and P2)
40H: Normal (cable disconnected on P1, loopback communication in progress on P2)
Stores the cumulative count that was detected for cable disconnections at the P1 side.
When 'Clear communication error count' (SB0006) is turned on, the stored value for the number of errors is cleared.
When FFFFH (maximum value 65535) is counted, the value returns to 0 and the module continues to count.
Stores the cumulative count that error data was received at the P1 side.
The count stores only error data that is not transmitted to all stations.
When 'Clear communication error count' (SB0006) is turned on, the stored value for the number of errors is cleared.
When FFFFH (maximum value 65535) is counted, counting stops.
Stores the cumulative count that data was received at the P1 side.
When 'Clear communication error count' (SB0006) is turned on, the stored value for the number of errors is cleared.
When FFFFFFFFH (maximum value 4294967295) is counted, counting stops.
Stores the cumulative count that was detected for cable disconnections at the P2 side.
When 'Clear communication error count' (SB0006) is turned on, the stored value for the number of errors is cleared.
When FFFFH (maximum value 65535) is counted, the value returns to 0 and the module continues to count.
Stores the cumulative count that error data was received at the P2 side.
The count stores only error data that is not transmitted to all stations.
When 'Clear communication error count' (SB0006) is turned on, the stored value for the number of errors is cleared.
When FFFFH (maximum value 65535) is counted, counting stops.
Stores the cumulative count that data was received at the P2 side.
When 'Clear communication error count' (SB0006) is turned on, the stored value for the number of errors is cleared.
When FFFFFFFFH (maximum value 4294967295) is counted, counting stops.
Stores the cumulative count that a link scan could not complete an Inter-module synchronization cycle.
The stored count is cleared by turning off and on the power supply or resetting the remote head module.
When FFFFH (maximum value 65535) is counted, counting stops.
By setting these areas as the refresh target device of the link special register (SW) of the CC-Link master/local
module, the data link status of CC-Link can be checked.
