7.2.3 Recommendations on the naming of identifiers

Identifiers are defined at the declaration of variables (Variable names), user-defined

data types and at the creation of POUs (functions, function blocks, programs) and

visualizations. You might follow the following recommendations concerning the

naming of identifiers in order to make it as unique as possible.

Variable names

The naming of variables in applications and libraries as far as possible should follow

the Hungarian notation:

• For each variable a meaningful, short description should be found, the base name.

The first letter of each word of a base name should be a capital letter, the others

should be small ones (Example: FileSize). If needed additionally an translation file

for other languages can be created.

• Before the base name, corresponding to the data type of the variable, prefix(es)

are added in small letters.
