Issue Number: 1
a data channel will only use 32 bits if the source/target drive parameter is a 32-bit
parameter. If the source/target drive parameter is only 1, 8 or 16 bits wide 16 bits will be
used for that particular data channel.
14.14 Serial number LS
The SI-Interbus module serial number is a 10-digit decimal number loaded during
manufacture and cannot be changed.
This parameter contains the last 8 digits of the serial number. (See also Pr MM.055 ).
14.15 Cyclic mapping status
If the SI-Interbus operating status parameter (Pr MM.006 ) indicates -3, a mapping
configuration error has been detected. The reason for the error is indicated by the
SI-Interbus mapping status parameter, Pr
MM.049 . When a mapping error has been
corrected, reset the SI-Interbus by setting Pr MM.032 to On.
The full list of mapping error codes can be found in the Diagnostics section
(see
Table 12-2 Mapping status codes ).
14.16 Module status
If SI-Interbus detects an error during operation, it will force a trip in the drive, and write
the SI-Interbus error code into this parameter.

If the mapping configuration size has changed (Pr MM.005 Interbus Data Format ), then
the module reset is insufficient to fully initialise the Interbus network and after saving
parameters, the module must be power-cycled.
