Table 8.1 Error code list (continued)
Description of error
<During execution of an online test>
Wait until SB0047 (baton pass status) and SB0049 (data link status) are
recovered.
<During execution of an offline test>
Change the switch setting to online after the test has been completed.
Review the station number setting.
The setup confirmation test of network diagnosis is effective.
If the setup confirmation test cannot be executed, identify the station where a
data link error has occurred in [Data-link status of each station] on the Other
station information screen of network diagnostics and then check the station
No. setting.
Review the station number setting.
The setup confirmation test of network diagnosis is effective.
If the setup confirmation test cannot be executed, identify the station where a
data link error has occurred in [Data-link status of each station] on the Other
station information screen of network diagnostics and then check the
parameters of the error station.
When the operation mode for redundant system is debug, connect one of the
systems to the network. When connecting to both systems to the network, set
the operation mode to back-up mode or to separate mode.
Review the mode setting, and change it to online.
Check for faulty cables, faulty hardware, incorrect cable wiring, absence of
terminating resistor (in the case of the bus), and duplication of station numbers,
control stations, and remote master stations.
The setup confirmation test and loop test of network diagnosis are effective.
Review the status of the corresponding station and the parameter and switch
settings (to see if there is a parameter error and the corresponding station is the
control station and properly set).
Confirm the power supply status of the corresponding station (to see if it is
repeatedly turned on and off).
Check for faulty cables, faulty hardware, incorrect cable wiring, absence of
terminating resistor (in the case of the bus), and duplication of station numbers,
control stations, and remote master stations.
The setup confirmation test and loop test of network diagnosis are effective.
Check for faulty cables, faulty hardware, incorrect wiring, and duplication of
station numbers, control stations, and remote master stations.
Confirm the power supply status of each module (to see if it is repeatedly
turned on and off).
Confirm whether network modules in MESLECNET/H and MELSECNET/10
modes exist together (confirm the control station type).
Retry after a little while.
If the error reoccurs as a result of a retry, check for faulty cables, faulty
hardware, incorrect cable wiring, absence of terminating resistor (in the case of
the bus), and duplication of station numbers, control stations, and remote
master stations.
Wait until SB0047 (baton pass status) and SB0049 (data link status) are
recovered.
Retry after a little while.
If the error reoccurs as a result of a retry, check for faulty cables, faulty
hardware, incorrect cable wiring, absence of terminating resistor (in the case of
the bus), and duplication of station numbers, control stations, and remote
master stations.
Wait until SB0047 (baton pass status) and SB0049 (data link status) are
recovered.
