6.7.3 Data conversion rule
Code carrier data formats
The following code-carrier data formats are supported:
● Data format: Explanation
● ASCII: ASCII character set
● INT: 16-bit integer (Intel format)
● BCD: Binary-coded decimal number (if necessary, with sign and decimal point)
Assignment between code carrier data and dialog data
Among other things, the conversion rule for Item<n> or BItem<n> includes the assignment to
no/one/multiple dialog variables, where appropriate with a conversion rule, which is
described in more detail in this section.
The general conversion rule for Item<n> or BItem<n> is as follows:
(B)Item<n>=<line>
<n>
<line
>

Dialog variable
<dialog variable> := <dvar1>[=(<uv>)] [, <dvar2>[=(<uv>)] [,<dvar3>
[&<dvar4>]=(<uv>)] [, <dvarN>[=(<uv>)]
<dvar> := T<index> | C<index> | -
T = tool data,
C = cutting edge data,
