Troubleshooting of Bridge Module
This section describes the troubleshooting of the bridge module.
When all LEDs of the bridge module are off even after powering off and on
When the LINK LED does not turn on or flash even after powering off and on
When the LINK LED of the bridge module does not flash
When the ALM LED of the bridge module is flashing at 0.2 second intervals
When the ALM LED of the bridge module is flashing at 1 second intervals
Item
Action
Check the power supply for correct wiring.
If the power supply is wired correctly, hardware failure may have occurred. Please
consult your local Mitsubishi representative.
Item
Action
Check the power supply voltage.
Check that the power supply voltage of the 24VDC external power supply is within
the rated value.
Check the wiring of terminal blocks.
• Check that the 24VDC external power supply is properly connected to the terminal
block of the bridge module.
• Check that there is no short-circuit or incorrect wiring and screws are tightened
within the specified torque range.
Check the power cables (24V, 0V).
• Check that the power cables (24V, 0V) are not disconnected or short-circuited.
• When crimping the link connector, check that the pin layout is correct.
Check the total internal current consumption of the entire system.
Review the system configuration so that the total internal current consumption does
not exceed the rated output current of the power supply module.
Item
Action
Check that the LINK LED is turned on.
A malfunction has been detected in the bridge module hardware. Power off and on
the bridge module.
If the error occurs again, the module may be in failure. Please consult your local
Mitsubishi representative.
Item
Action
Check the power supply voltage of the 24VDC external power supply.
Adjust the power supply voltage of the 24VDC external power supply which is
connected to the bridge module to be within the rated value (21.6 to 27.6VDC). The
recommended voltage is 26.4VDC.
Check the power cables (24V, 0V).
• Check that the power cables (24V, 0V) are not disconnected or short-circuited.
• When crimping the link connector, check that the pin layout is correct.
Check the wiring of terminal blocks.
• Check that the 24VDC external power supply is properly connected to the terminal
block of the CC-Link master module or the slave module.
• Check that there is no short-circuit or incorrect wiring and screws are tightened
within the specified torque range.
Item
Action
Check that the transmission cables (DP, DN) are not short-circuited.
• Check that the transmission cables (DP, DN) are not short-circuited.
• When crimping the link connector, check that the pin layout is correct.
Check the wiring of terminal blocks.
Check that the transmission cables (DP, DN) are not in contact with each other and
that there is no incorrect wiring in the terminal block wiring of the bridge module and
the slave module.
Check that the current consumption of the AnyWireASLINK system is
within the specified range.
Correct the cables (wire diameter, total length) and modules (type, the number of
connected modules) so that the total current consumption of all the slave modules
does not exceed the transmission cable supply current of the bridge module.
