SW0073 Cyclic transmission time
(calculation value)
Stores the cyclic transmission time calculated by the number of
device stations and the number of points that are set in "Network
Configuration Settings" under "Basic Settings". (Unit: s)
SW0074 PORT1 cable disconnection
detection count
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 count is cleared.
When FFFFH (maximum value 65535) is counted, the value returns
to 0 and the module continues to count.
SW0075 PORT1 receive error
detection 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 count is cleared.
When FFFFH (maximum value 65535) is counted, counting stops.
SW0076 PORT1 total number of
received data (lower 1 word)
Stores the cumulative count that data was received at the P1 side.
When 'Clear communication error count' (SB0006) is turned on, the
stored count is cleared.
When FFFFFFFFH (maximum value 4294967295) is counted,
counting stops.
SW0077 PORT1 total number of
received data (upper 1 word)
SW0078 Transient transmission time
(calculation value)
Stores the transient transmission time calculated by the number of
device stations and the number of points that are set in "Network
Configuration Settings" under "Basic Settings". (Unit: s)
SW007C PORT2 cable disconnection
detection count
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 count is cleared.
When FFFFH (maximum value 65535) is counted, the value returns
to 0 and the module continues to count.
SW007D PORT2 receive error
detection 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 count is cleared.
When FFFFH (maximum value 65535) is counted, counting stops.
SW007E PORT2 total number of
received data (lower 1 word)
Stores the cumulative count that data was received at the P2 side.
When 'Clear communication error count' (SB0006) is turned on, the
stored count is cleared.
When FFFFFFFFH (maximum value 4294967295) is counted,
counting stops.
SW007F PORT2 total number of
received data (upper 1 word)

SW00B7
Data link status of each
station
Stores the data link status of each station.
0: Data link normally operating station
1: Data link faulty station
• If multiple stations change from faulty to normal, because they are
reconnected to the network one by one per cycle, the time until
the status changes to "0: Data link normally operating station"
may vary by several seconds.
• If no response is received for several cycles, the station is
determined to be a data link faulty station.
Since a local station cannot obtain the station information of the CC-
Link IE TSN Class A remote station when communicating in
multicast mode, "0: Data link normally operating station" is reflected
to the CC-Link IE TSN Class A remote station.
(Conditions)
• Stations that surpass the maximum station number are ignored.
(Also used in the CLPA conformance test.)

Reserved station setting
status
Stores the reserved station setting status of each station.
0: Station other than a reserved station
1: Reserved station
(Conditions)
• Stations that surpass the maximum station number are ignored.
