Description
Stores the setting value of the communication cycle intervals set with the module
parameter of the master station. (Unit: s)
Stores the setting value of the system reserved time set with the module parameter of the
master station. (Unit: s)
Stores the setting value of the cyclic transmission time set with the module parameter of
the master station. (Unit: s)
Stores the setting value of the transient transmission time set with the module parameter
of the master station. (Unit: s)
Stores the setting value of the multiple cycle setting (medium speed) set with the module
parameter of the master station.
Stores the setting value of the multiple cycle setting (low speed) set with the module
parameter of the master station.
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)
10H: Normal (cable disconnected on P1, communication in progress on P2)
11H: Disconnected (cable disconnected on P1 and P2)
12H: Disconnected (cable disconnected on P1, establishing line on P2)
21H: Disconnected (establishing line on P1, cable disconnected on P2)
22H: Disconnected (establishing line on P1 and P2)
Stores the communication cycle intervals that were calculated by the number of device
stations and the points set in "Network Configuration Settings" of "Basic Settings". (Unit:
s)
Stores the cyclic transmission time that was calculated by the number of device stations
and the points set in "Network Configuration Settings" of "Basic Settings". (Unit: s)
Stores the cumulative count of cable disconnections detected at the PORT1 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 of error data receptions at the PORT1 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 of data receptions at the PORT1 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 that are calculated by the number of device
stations and the number of link device points set in "Network Configuration Settings" of
"Basic Settings". (Unit: s)
Stores the processing time for checking the watch dog counter calculated from the device
stations which are actually connected. (Unit: s)
Stores the time which needs to be added to "Communication Period Interval Setting" and
"Transient Transmission Time" set in "Communication Period Setting" under "Basic
Settings". (Unit: s)
Stores the cumulative count of cable disconnections detected at the PORT2 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.
