12.36.9 List of descriptions
This file describes the conversion. The syntax used and described as follows has been kept in
terms as general as possible to also allow other conversions, i.e. it is the responsibility of the
user to change the file in such a way that the most different conversion algorithms can be
implemented.
Various types of machine data are grouped in sections which are introduced under a heading
as known from the 840C-MDD list block:
TEA1 n for general machine data
TEA1 a for axis-specific NC machine data
TEA4 k for channel-specific cycles machine data
TEA2 n for PLC machine data
IKA1 ibz for IKA configuration
IKA2 ifk for IKA configuration
IKA3 ipk for IKA points
Under the list of descriptions, only the above-mentioned types of data are permissible and
valid for conversion. At least one section has to be quoted with a machine data. The sequence
of the sections is immaterial. Comments can be added to the file (introduced by a double slash
= //) then the rest of the line is ignored right to the end of the line. By entering space lines the
list can be structured. Blank spaces are also possible.
There are basically two types of conversion instructions:
• Direct assignment
A fixed value is specified for each of the two modes and entered into the machine data.
The type of the value has to suit the type of data of the machine data.
Always indicate both values.
The value of the original data record is normally checked to avoid errors.
A string of bits is started with 0b...
• Linear formula
The new value is calculated from the old value.
The formula can also be used in reverse, however, it must not contain a decimal fraction
as factor and offset.
