11 TROUBLESHOOTING
(1) Initial error code (BFM#105)
(a) This address stores the error codes generated when the initial processing is
executed.
(b) Error codes are stored as binary values when the initial abnormal
completion signal (BFM#28...b5) is on.
(c) An error code is cleared when the initial normal completion signal
(BFM#27"0001
H
", BFM#28...b0: ON) is turns on, but can also be cleared by
the following operations.
1) Writing the value in BFM#1600 to perform re-initialization or turning off
the PLC and Ethernet module
2) Re-downloading the parameter with FX Configurator-EN (GX
Developer) or sequence pragram
(2) Open error code
(connection numbers: 1 to 8; BFM#124 to 194)
(a) These addresses store the result of the open processing for the applicable
connections.
(b) The results of the open processing are stored in binary values.
0 : Normal completion
Other than 0 : Abnormal completion (BFM#28...b0: ON)
(c) An error code is cleared by the following operations.
1) Reopening the connection that caused an open error
2) Performing the re-initial processing by writing the value to BFM#1600
(3) Fixed buffer sending error code
(connection numbers: 1 to 8; BFM#125 to 195)
(a) These addresses store error codes generated when an error in data
sending to an external device occurs during fixed buffer communication
using the applicable connection.
(b) A sending error code is cleared when the next data sending is normally
completed.
(4) Connection end code
(connection numbers: 1 to 8; BFM#126 to 196)
(a) These addresses store end codes returned from an external device as a
response during the fixed buffer communication using the applicable
connection.
(b) Determine how to handle the end codes in the responses by arranging with
the particular external device.
