stopped.
Execute the line test while link is
executed.
B302
Specified station number
setting error
When the request for temporary error invalid station or
the request for cancel of temporary error invalid
station was given, the specified station number was
beyond the maximum communication station number.
Specify a station number not more
than the maximum communication
station number.
B303
Specified station number no-
setting error

intelligent device station is
operational and that the cable is not
disconnected.
B305

station was given, a head station was not specified.
Specify a head station in giving the
request for temporary error invalid
station or the request for cancel of
temporary error invalid station.
B307 Data link error in all stations
When the following request was given, there was data
link error in all stations.
• Data link restart (SB0000)
• Data link stop (SB0002)
Wait until the data link becomes
normal, then give the request again.
B308
Station number setting error
(loading status)
The station number of a slave station is not set inside
the range from 1 to 16.
Set a slave station number inside the
specification range (1 to 16).
B309 Station number overlap error
In connected units, a station number overlaps
(including the number of occupied stations, excluding
overlap of a head station number).
Check the station numbers of the
units. (Including the number of
occupied stations.)
B30A
Loading/ parameter
consistency error
The station type is different between the unit and the
parameter.
Set the parameter correctly.
B30B
Loading/ parameter
consistency error
The loading status is not consistent with the network
parameters.
Align the loading status with the
network parameters.
B30D Initial status
