value error
Occurrence ID is
stored.
The slave unit has detected a signal for writing a
parameter which cannot be set to itself.
After narrowing down error IDs, check that the
set value of the slave unit parameter is within
the settable range.

error
Occurrence ID is
stored.
Check for any problems due to noise.
305 131 Parameter
access
error
Occurrence ID is
stored.
The slave unit provides notification of error
status.
Check the details of the target unit status and
remove the cause of the fault.
400 190 ID
redundancy
error
Occurrence ID is
stored.
A redundant address (ID) is set for a connected
slave unit.
After narrowing down error IDs, check the
setting of the slave unit address (ID), and set the
ID so that there will be no redundancy.

ID not set error
Occurrence ID is
stored. (255 or
767)
There is a slave unit whose address has not
been set (default setting).
Perform the following:
Set the slave unit address.
Check that the slave unit address is not set to
255.
7.1.1.9 Redundant address (ID)
During automatic address recognition, a redundancy check is carried out on the registered connection IDs
(addresses) and the results are saved.
Up to 12 redundant IDs can be displayed.
The redundant ID (address) list is as follows.
