Troubleshooting FINS Commands
Section 7-6
7-6 Troubleshooting FINS Commands
Any problems in FINS communications can be determined using the response
codes when the CMND(490) instruction has been used. The table below lists
response codes returned by the PROFIBUS-DP Master Unit, after execution
of FINS commands, the probable cause of errors, and recommended reme-
dies. Refer to the
Communications Commands Reference Manual (W342) for
further information on response codes.
Main code Sub-
code
Probable cause Correction
00: No errors 00 --- ---
02: Remote node
error 03 A FINS command was sent to read/write
specific slave data or to control a slave, but
the specified slave is not allocated to the
PROFIBUS -DP Master Unit. Specify only addresses of allocated slaves in
the FINS command.
04: Service not
supported. 02 A FINS command, which is not supported
by the Unit/Model has been sent. Check the command code and be sure the
command is supported by the Unit.
10: Command for-
mat error 01 The command is longer than the max. per-
missible length. Check the command format of the command
and set it correctly.
02 The command is shorter than min. permis-
sible length. Check the command format of the command
and set it correctly.
11: Parameter error 03 The first word is in an inaccessible area or
the bit number is not 00. Set a first word that is in an accessible area.
The bit number must be 00 for Ethernet Units.
0C Parameters are set incorrectly in the com-
mand data.
• Non-specified code used.
• Invalid slave address (exceeds 125).
• Invalid code in program number
(exceeds 128)
• The number of read records is 0.
Check the command data and correct any
parameters that are incorrect.
22: Status error
(operating mode
disagreement) 08 A FINS command was sent to retrieve
slave data, but the Master Unit is in the
wrong mode to access the slave station. Change Master mode to either CLEAR or
OPERATE, before re-sending the FINS com-
mand.
25: Unit Error 0F An attempt to clear the Error Log failed. Re-send the ERROR LOG CLEAR FINS com-
mand. If the problem persist, non-volatile mem-
ory may be corrupted. Replace the Unit.
26: Environment
error (no such Unit) 05 A FINS command was sent to enable or
disable a slave station from the poll list, but
the targeted slave is already in that mode. No need to sent the FINS command again,
unless a change to the slave state needs to be
made.
0B Cannot clear the Error Log. The Error
cause still exists. Remove the error cause and Re-send the
ERROR LOG CLEAR FINS command.
