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 Error No.
(FS on, # of (FS off, # of
FN pulses) FN pulses)

The Parameter Error Numbers listed for Error Type 1below refer to NIU model
IC670PBI002 only. For IC670PBI001, Error Type 1 indicates that an error has
occurred during configuration of the NIU. Check the configuration.

Meaning
An invalid module number
was used. (IC670PBI002)
A parameter block is not
complete.
The data length of the
parameter block is too short.
The data length of the
parameter block is too long.
The internal block for
configuration, failsafe
values, and PCP is too
small.
The header byte for the
module parameter is
incorrect.
PCP initialization for a
module without PCP
functions.
Too many data blocks for
the module.
Incomplete data block in a
deactivated module.
Remedy
Check whether the module
can be parameterized.
The number of modules does
not correspond to the
parameter blocks.
Check the number of
parameters.
Check the number of
parameters.
Check the structure of the
parameters for the modules.
Check the first byte of the
module parameters.
Check the configuration.
The number of modules does
not correspond to the
parameter blocks.
Check the number of
parameters.
