Determining the Error Cause and Remedy from the NIU LEDs
The type of error and the error number can be determined using the FS and FN
LEDs on the NIU.
▪
FS ON: the number of flashing pulses on FN indicates the type of error.
▪
FS OFF: the number of flashing pulses on FN indicates the error number.
This information can be used to determine the type of error from the following
table.
Example:
FS is on, the FN LED flashes three times simultaneously. The FS LED
goes out and the FN LED flashes four times. The error is caused by the use of a
module type that is not permitted.
Error Type
(FS on, # of
FN pulses) Error No.
(FS off, # of
FN pulses) Meaning Remedy
Parameter Error on Profibus (SET_PRM telegram)
The Parameter Error Numbers listed for Error Type 1 below refer to NIU model
IC670PBI002 only. For IC670PBI00 1 , Error Type 1 indicates that an error has
occurred during configuration of the NIU. Check the configuration.
1 An invalid module number
was used. (IC670PBI002) Check whether the module
can be parameterized.
2 A parameter block is not
complete. The number of modules does
not correspond to the
parameter blocks.
3 The data length of the
parameter block is too short. Check the number of
parameters.
4 The data length of the
parameter block is too long. Check the number of
parameters.
5 The internal block for
configuration, failsafe
values, and PCP is too
small. Check the structure of the
parameters for the modules.
6 The header byte for the
module parameter is
incorrect. Check the first byte of the
module parameters.
7 PCP initialization for a
module without PCP
functions. Check the configuration.
8 Too many data blocks for
the module. The number of modules does
not correspond to the
parameter blocks.

9 Incomplete data block in a
deactivated module. Check the number of
parameters.
