Error description
DP/DN disconnection error
Slave module hardware error
Parameter access target module ID
error
Parameter value error
Corrective action
The transmission cables (DP, DN) may be disconnected, or there
may be no response from the slave module. The slave module may
be in failure or the system configuration may have been changed
after the automatic address detection. Check Number of the error IDs
(Un\G8192) and Error ID information storage area (Un\G8193 to
Un\G8320), find out the disconnected area, and perform the
following:
• Check that the transmission cables (entire cables) are free from
disconnection.
• Check that the cables have been crimped with proper pin layout
using link connectors appropriate to the wire diameter.
• Check that the transmission cables (DP, DN) are properly
connected to the terminal block of the master module.
• Check that there is no incorrect wiring and screws are tightened
sufficiently.
• When creating a new system, adding or removing a slave module,
or changing the address of the slave module, perform the
automatic address detection. After performing the automatic
address detection, check that the number of slave modules and
the address are consistent with those of the actual system.
• If the LINK LED of the slave module does not flash, check that
there is no disconnection, short circuit, incorrect wiring, or poor
contact in the transmission cables (DP, DN) around the module.
A malfunction has been detected in the slave module hardware.
Perform either of the following operations:
• Reset the CPU module, or power off and on the system.
• Power off and on the slave module.
Check that there is no influence from noise.
The master module accessed the parameter of the ID where the
automatic address detection has not been performed. Check
Number of the alarm IDs (Un\G9984) and Alarm ID information
storage area (Un\G9985 to Un\G10112), find out the error ID, and
perform the following:
• Check that the slave module ID for parameter access in the actual
system matches that of the program. Especially note that the input
slave module ID is the input slave module address + 200
the I/O combined slave module ID is the I/O combined slave
module address + 200 .

• When creating a new system, adding or removing a slave module,
or changing the address of the slave module, perform the
automatic address detection. After performing the automatic
address detection, check that the number of slave modules and
the address are consistent with those of the actual system.
The slave module has detected a signal of writing a parameter that
cannot be set to the slave module itself.
Check Number of the alarm IDs (Un\G9984) and Alarm ID
information storage area (Un\G9985 to Un\G10112) to find out the
error ID. Then check that the slave module parameter setting value is
within the allowable setting range.
