Configuring alarms
13.4 PLC alarms with parameters
%[i]b
%[i][.y]f
If the optional digit specification i is not specified, then only the number of digits is used
required to completely display the number. The same applies when the number of digits
specified by i is not sufficient to completely display the number including sign, i.e. i is then
ignored.
The number contained in the format statement does not relate to the position of the
associated value in the alarm PDU, but to the position of the parameter description in the
parameter statement. Any number of format statements can be present in an alarm text.
Examples
@1%b@
@2%8X@ →
