4.7 Completion Status
Indicated below are the completion statuses that DN211 returns to the T2/T2E/T2N.
Except for normal completion, an error code and the local node address are indicated alternatively
on the 7-segment LED on the front panel of the DN211. The error code indication stops when the
following request is completed successfully.
Table 4.17 List of Completion Statuses
Completin status Code Description
Normal completion 0001H Indicates a request is completed successfully.
Local station failure 00A0H
When a request for inhibited processing is
requested in down mode
Serial number unregistered 00A1H
When a serial number registered in the DN211
disappeared → Ask for repair because the DN211
needs resetting.
Local station parameters
unassigned
00A2H
A request for inhibited processing is issued when no
local station parameters are set
Length abnormal 00A3H
When the data size of a bit strobe output data write
request is 8 bytes or more
Station mode abnormal 00A4H
When a request for inhibited processing is issued
during run mode time
When a request for inhibited processing is issued
during standby mode time
00A5H Reserved
Transmission inhibition status 00A6H
When a request relating to transmission processing
is issued in transmission inhibition state by the
T2/T2E/T2N
Format abnormal 00B0H
When the requested processing code is not
supported
00B1H

When invalid data is found in the composition data
for parameter setting request (see trace information
(Event history) for detail)
00C1H
Input/output data of a slave device cannot be
allocated to the input/output data area (when
operation mode control request "RUN" is issued).
