202 CA DP, DN
disconnection
error
Error ID is stored. The DP, DN signal lines may be disconnected,
or there may be no response from slave units.
The system configuration may have been
changed after slave unit failure or automatic
address recognition. Narrow down the
disconnected area by using error ID information
or similar method, and then perform the
following:
 Check that there are no disconnections in any
transmission line. Also check that a link
connector that is appropriate for the particular
wire diameter is used and it is crimped with the
correct pin assignment.
 Check that signal lines are correctly connected
to the terminal block. Also check that there is
no miswiring or insufficient tightening of
screws.
 When newly creating a system or altering the
system (adding or eliminating slave units,
changing addresses), please carry out
automatic address recognition. Then, check
that the number of slave units and addresses
are the same as those of the actual system.
 If the slave unit "LINK" LED is not flashing,
check the transmission line for disconnection,
short-circuit, miswiring, or contact failure near
the unit.

301 12C
12D Slave unit
hardware error Occurrence ID is
stored. Slave unit hardware malfunction has been
detected.
Turn the power of the slave unit off and on.
Also, check for any problems due to noise.
302 12E Parameter access
target ID error
As this error is not
dependent on
individual slave
units, the
"0x0FFF" value is
stored. Parameter access has been performed for an ID
whose address has not been automatically
recognized. Narrow down error IDs by checking
the alarm ID information in the memory.
 Next, perform the following: Check if the slave
unit ID of the parameter access target in the
program matches the ID of the actual system.
Note that the ID of the input slave unit and the
ID of the input/output mixed slave unit are their
add200H.
 Carry out automatic address recognition when
newly creating a system or altering the system
(adding or eliminating slave units, changing
addresses).
Then, check that the number of slave units
and addresses are the same as those of the
actual system.
