Review the station number setting.
The setup confirmation test of network diagnosis is effective.
Review the station number setting.
The setup confirmation test of network diagnosis is effective.
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 recurs 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 recurs 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.
Check for faulty cables, faulty hardware, incorrect wiring, duplication of station
numbers, and duplication of control stations.
Check for faulty cables, hardware failure, noise, incorrect wiring, and absence
of terminal resistors (when a bus is used).
Wait until SB0047 (baton pass status)/SB0049 (data link status) is turned off
(normal).
Wait for a while and execute again.
Review the parameter and switch settings (to see if there is a parameter error
and the corresponding station is the control station or remote master station
and properly set).
Check for faulty cables, faulty hardware, noise, incorrect wiring, and duplication
of station numbers, control stations, and remote master stations.
The hardware of the network module is faulty.
