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 "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 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: 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)
40H: Normal (cable disconnected on P1, loopback communication in progress on
P2)
Stores the number of the station where a loopback is being performed.
0: No loopback stations
1 to 120: Station number of the slave station or submaster station carrying out
loopback
125: Master station carrying out loopback
(Conditions)
This relay is enabled when 'Data link status of own station' (SB0049) is off, or
'Network topology setting' (SB0078) is on. When 'Data link status of own station'
(SB0049) is turned on (error), data prior to error is held.
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.
