Description
Stores the status of the CPU module on the own station.
00H: No CPU module mounted
01H: STOP (normal)
02H: STOP (moderate/major error)
03H: STOP (minor error)
04H: RUN (normal)
05H: RUN (minor error)
07H: PAUSE
0EH: Reset in progress
0FH: Initial processing in progress
Stores the status of parameter settings.
0: Normal
1 or greater: Error definition (Error code is stored.)
(Conditions)
• This register is enabled when 'Received parameter error' (SB004D) is on.
Stores the total number of slave stations that are set by the parameters.
Range: 1 to 64
Stores the total number of slave stations that are actually connected by data link.
Range: 1 to 64 (0 when own station is disconnected)
Stores the maximum station No. of the station where the data link is normally performed.
Range: 1 to 64 (0 when own station is disconnected)
(Conditions)
• This register is enabled when 'Data link error status of own station' (SB0049) is off.
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 "Cyclic Transmission Time" of "Basic Settings". (Unit: s)
Stores the setting value of "Transient Transmission Time" of "Basic Settings". (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)
01H: Normal (communication in progress on P1)
10H: Normal (cable disconnected on P1)
11H: Disconnected (cable disconnected on P1)
12H: Disconnected (cable disconnected on P1)
21H: Disconnected (establishing line on P1)
22H: Disconnected (establishing line on P1)
Stores the communication cycle intervals that are calculated by the number of slave stations and the number of link
device points set in "Network Configuration Settings" of "Basic Settings". (Unit: s)
Stores the cyclic transmission time that are calculated by the number of slave stations and the number of link
device points set in "Network Configuration Settings" of "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 that are calculated by the number of slave stations and the number of link
device points set in "Network Configuration Settings" of "Basic Settings". (Unit: s)
