Technical designations are linguistically neutral (mnemonic). They are based on
mnemonic texts set up in the library, with additional project-specific details.
The TD is defined by Siemens. The User Designation (UD) can be defined by
the customer.
Each element of the TD is called
ShortName . A ShortName is a designation for
an individual plant element within the automation station. A
ShortName is
always linked to a description. This pair is called the
Name&Description_Pair .
TD rules
Item Rule
Address structure Comprises at least one hierarchical object and one function object
Has a variable length (site + 1..8 hierarchy and function objects + pin name)
Is independent of the automation station, that is, does not contain a designation
for an automation station
Must be unique for each site
Mnemonic Based on the English terms
Must not be translated
Plant elements on the same hierarchy level are distinguished through different
part names, e.g., HG01/HG02.
Syntax Site designation Consists of upper and lower case letters, and numbers (must start with a letter):
[a..z, A..Z, 0..9].
Is case insensitive, e.g.,
Imax and IMAx are treated the same.
Other partial designations Consist of upper and lower case letters ([A..Z] and [a..z]) and/or numbers 0 to 9.
Is case insensitive, e.g.,
Imax and IMAx are treated the same.
Max. number of characters Site: 10
Object: 9
Pin: 8
TD: 80
Separators Colon (:) after site name
Apostrophes (‘) for all other separations
Period (.) in front of pin name
Function blocks and pins
A function block, that is, an object with pins, can represent an area, a partial
plant, a sub-area, an aggregate, a section, or a component. Function blocks
have attributes and function block pins have attributes.
The following figure shows a function block and its pins as they appear in the
program view:
The main attributes of the function block are:
● Name : Name of the function block based on the key of the TD. Example:
ThOvrld
●
Description : Additional description. For generic operation it is shown as text
in an operator unit. Example: Thermoelectrical ovrld
