Diagnostics support by configuring your own extended alarm text

In order to upgrade the level of diagnostics information when an error occurs, cer-
tain Safety Integrated system alarms can be supplemented by a freely–definable
user text. For instance, for hardware–related faults, supplementary information
such as input designation, circuit diagram identification number or similar can be
included in the system alarm that is output.
This extended alarm text is based on the interaction between the NCK system soft-
ware (that specifies the parameter that addresses the supplementary information
for the alarm text) and the HMI software (that has to appropriately process this
parameter).
Dedicated extended alarm texts can be defined for the following Safety Integrated
system alarms:
S General SPL crosswise data comparison errors (different status of the SPL
variables) Alarm 27090, error for crosswise data comparison, NCK–PLC
S Channel–related errors on the PROFIsafe module (only when using the ET 200
PROFIsafe I/O)
Alarm 27254 PROFIsafe: F module, error on channel
Prerequisites, HMI Advanced
The following entry is in the configuration file for the alarm server (file MBDDE.INI)
in the section [Text files]:
File excerpt: mbdde.ini
[Textfiles]
NCK=f:\dh\mb.dir\aln_
This means that all of the NCK alarms are defined in the file referenced after the
NCK entry. The processing of an extended alarm text for the above specified
alarms is prepared as part of this definition.
File excerpt: aln_gr.com
027090 0 0 "Error for crosswise data comparison NCK–PLC, %1[%2], NCK:
%3; %4<ALSI>"
027254 0 0 "PROFIsafe: F module %1, error in channel %2; %3<ALSI>"
Using the supplement %4<ALSI> (Alarm 27090) and %3<ALSI> (Alarm 27254),
the possibility of providing an alarm text extension is defined for the alarm.
Principle of operation – extended alarm text
If Alarm 27090 or Alarm 27254 occurs, the NCK transfers an additional parameter
value to the HMI software (27090: %4; 27254: %3). This parameter has a defined
value range. Each value can be uniquely assigned an extended alarm text.
