Variable

names

The conventions used by Lenze for the variable names of its system blocks, function blocks and
functions are based on what is known as "Hungarian Notation". This allows you to identify the
most important properties (e.g. the data type) of a variable immediately by means of its name,
e.g. DIGIN_bIn1_b.

You will find information about the conventions in the appendix of the DDS Online
documentation "Introduction to IEC1131-3 programming”.
