There are no strict rules on how to build a short name, but the following methods
should be considered:
If there is no risk for misunderstanding, different full names can have the same
abbreviation. In Appendix A, Names and Abbreviations a list of names and their
abbreviations are presented.
The IEC 61131-3 and IEC 61131-5 (the latter only for communication, excluding
FOUNDATION Fieldbus) standards and guidelines shall be followed for naming of
object types. This is also valid for libraries, parameters, as well as data types.
Note that some words, for example IF, THEN, ELSE (not case sensitive), are
keywords recognized by the 61131-3 standard and cannot be used.
Suffixes
A group of object types may also have a common suffix describing the data type
they should be applied to, for example Add4Int and Mult4Int. Most object types in
the control libraries have the suffix -CC, which indicates that they should be applied
to the data type Control Connection.
