13.4 PLC alarms with parameters
Introduction
For alarms that are triggered via the PLC blocks SFC17 and SFC18, a parameter can be
transferred each time the block is called. If the "Octet string" data type is selected, up to 12
bytes can be transferred.
With an appropriate configuration of the operating software, a maximum of 12 bytes can be
interpreted, e.g. also as an array of bytes or as a structure with any order of simple data types.
In this way, several parameters can be displayed in the alarm text.
A parameter description must be stored for each alarm in the operating software. Two aspects
must be taken into account with this parameter description:
● How the parameter has to be interpreted correctly (data type and, if necessary, length)
● How the parameter has to be prepared for display (string or number, decimal, hexadecimal,
binary, etc.)
Point 1 is irrespective of the language selected for the display, point 2 can be different
depending on the national language.
The possible parameter descriptions are therefore divided into a language-independent
parameter statement and a language-dependent format statement and stored in the following
directories:
● Parameter statement:
● Format statement:
The names of the files can be freely selected. The parameter statement is added to the
configured data of the relevant alarm in the database in the form of the alarm attribute
"HMIPROPARAMDESCR2". Because of the language dependency, the format statement is
part of the alarm text.
