Description
Stores the cyclic transmission time calculated by the number of
slave stations and the number of points that are set in "Network
Configuration Settings" under "Basic Settings". (Unit: s)
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.
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.
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.
Stores the transient transmission time calculated by the number of
slave stations and the number of points that are set in "Network
Configuration Settings" under "Basic Settings". (Unit: s)
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.
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.
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.
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
authentication Class A remote station when communicating in
multicast mode, "0: Data link normally operating station" is reflected
to the remote station.
(Conditions)
• Stations that surpass the maximum station number are ignored.
(Also used in the CLPA conformance test.)
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.
(Also used in the CLPA conformance test.)
