8.4.2 Terminology used by the Parameter Manager
Term Description
User codes User-specific codes (user codes) can be assigned for variables applied in the user’s IEC 61131-3 program.
The user codes depend on the automation system and range between C3000 and C7999.
Code properties Code properties (read only, read/write, direct acceptance or direct acceptance when confirmed, for
example) can be defined for each assigned code.
Code value The code value is the value displayed or entered via the code (using GDC, Keypad or the parameter
monitor).This variable corresponds to the physical value known as variable value in the user program
(scaling).
Display text User-specified texts are displayed for parameterization/diagnostics using the Keypad. The text can have up
to 13 characters and is displayed for the code.
Input window with yellow
background colour If the user changes a standard setting, the background colour of the field changes to yellow.
In such cases, no changes in the Type Parameter Manager for this field will be considered.
Units Numerical values can also be assigned physical or defined units, such as rpm, Nm, bottles/min, etc.
First instances When using Lenze function blocks, the instances of these FBs (e.g. of 9300 Servo V2.0) can be assigned
all Lenze parameter codes standard for FBs using the function First instance .
Post-editing of the parameter codes is then not possible.
The parameter code assignment can be revoked completely.
Lenze function blocks can be linked with any codes.
Lenze supplies code-parameterized function blocks for standard tasks.
For PLC devices, the function blocks are used through linking a library (e.g. LenzeDrive.lib).
If the function block (e. g. L_NSET) is to be assigned standard parameterization codes, the function block
will be instanced as L_NSET1 of type L_NSET.
First instancing
The codes, including scaling, for this function block can be created in the Parameter Manager.
Parameterization program
languages GDC or the parameter monitor display every code together with a max. 35 character long text for
parameterization/diagnostics. This text can be defined in several languages (standard
language/language1/language2) in the Parameter Manager.
The language can be selected when the GDC description file is created so that the user decides the
language to be used for text displays.
Initialization An initial value can be assigned to the code to be accepted as initial value in the code’s default setting
(C0002).
Instance Parameter Manager Assignment of codes for variables used by the created program POUs or for the global variables of a
project.
Scale factor/scale function Internal variables can be shown more transparently using scale factors.
The IEC 61131-3 program uses a 16-bit value (e.g. integer) for example, while the scale function allows a
value between
±200% to be set in the GDC. The 16-bit value is simply scaled from ±32767 to ±200.
The user can define the limits of the value range in the code, so that the integer value of the code can only
be set between
±16384 ® ±100%, for example
Scale functions allow complex scaling operations. Scale functions are small IEC 61131-3 programs and
can be programmed by the user. The program may contain internal conversion scaling operations, limit
value calculations, etc.
Subcodes Subcodes are assigned automatically if the variable is an Array data type.
Example:
var1:ARRAY[0..4] OF INT
(up to 5 subcodes assigned)
All subcodes are given the same initialization value in the Parameter Manager.
Type Parameter Manager Definition of a standard setting
Predefinition of variables of created function block POUs
Variable types Variables of type VAR_IN_OUT and variables within a type VAR function block cannot be assigned
codes.
Variable value The variable value is the value processed in the IEC 61131-3 program (e. g. integer value of 16384).
