15.1.2 Conventions used for input/output identifiers
This chapter describes the conventions used for the identifiers of the inputs/outputs of the
blocks. The conventions ensure a uniform and consistent terminology and make reading
and comprehending the interconnection and application easier.
Tip!
The conventions used by Lenze are based on the "Hungarian Notation". This
ensures that the most significant characteristics of the corresponding
input/output (e.g. the data type) can be instantly recognised from its identifier.
An identifier consists of
a data type entry
an identifier (the "proper" name of the input/output)
an (optional) signal type specification
Data type entry
The data type entry provides information about the data type of the corresponding
input/output:
Identifier
The identifier is the proper name of the input/output and should indicate the application
or function.
Identifiers always start with a capital letter.
If an identifier consists of several "words", then each "word" must start with a capital
letter.
All other letters are written in lower case.
Data type entry Meaning Resolution Value range
bBOOL 1 bit0 ≡ FALSE / 1 ≡ TRUE
dn DINT 32 bits -2147483647 ... 2147483647
n INT 16 bits -32767 ... 32767
w WORD 16 bits 0 ... 65535
