This extended alarm text is based on the interaction between the NCK system
software (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:
•
•
Prerequisites, HMI The following entry is located in the configuration file for the alarm server (file
Advanced 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

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>"
An extended alarm text can be defined for an alarm using the supplement
%4<ALSI> (Alarm 27090) and %3<ALSI> (Alarm 27254). If required, this entry
can be subsequently entered into older HMI software versions, in order to
activate the display of the extended alarm text – under the assumption that the
NCK system software supports this.
Principle of operation If Alarm 27090 or Alarm 27254 occurs, the NCK transfers an additional
– extended alarm text parameter value (27090:%4; 27254: %3) to the HMI software. This parameter
has a defined value range. Each value can be uniquely assigned an extended
alarm text.
