Troubleshooting of Slave Module

This section describes the troubleshooting of the slave module.
When I/O data and parameter data cannot be checked
Item
Check the CC-Link network parameter setting in GX Works2.
Check the I/O LED status of the slave module.
Check that two or more bridge modules are not connected within one
AnyWireASLINK line.
When the I/O data and parameter data of the slave module is unstable
Item
Check the connection of the terminating unit.
Check the total length of the transmission cables (DP, DN).
Check the specifications of the transmission cables (DP, DN).
Check the power supply voltage of the 24VDC external power supply.
Check that the slave module does not have the same address as the
addresses of other slave modules.
Check that two or more bridge modules are not connected within one
AnyWireASLINK line.
Check that AnyWireASLINK bridge modules of different series are not
connected within one AnyWireASLINK line.
Check that a bridge module and an AnyWireASLINK master module

10.5 Troubleshooting of Slave Module
Action
• Check that the data areas which RX/RY and RW are assigned are correct.
• Check that the station information of CC-Link is correctly set in the bridge module
setting.
• Check that the CPU module is set to STOP status. Slave module cannot output
when the CPU module is set to STOP.
Check the I/O LED status of the slave module and check that there is no
disconnection, short-circuit, or poor contact in the wiring on the load side.
Connect only one bridge module within one AnyWireASLINK line.
Action
Pay attention to the polarities of the terminating unit and connect it properly.
Adjust the total length of the AnyWireASLINK system to be within the specification
range.
• Use transmission cables (DP, DN) that satisfy the specifications such as the type,
wire diameter, and tightening torque to the terminal block.
• Do not run multiple transmission cables (DP, DN) using a multicore cable.
Adjust the power supply voltage of the 24VDC external power supply to be within the
rated value (21.6 to 27.6VDC). The recommended voltage is 26.4VDC.
Set a unique address in the slave module.
Connect only one bridge module within one AnyWireASLINK line.
Connect only one AnyWireASLINK bridge module within one AnyWireASLINK line.
Connect either a bridge module or an AnyWireASLINK master module within one
AnyWireASLINK line.
