Ext. data type
Use the field Ext. data type to assign one of the following special data types to a code:
Data type Decimal code Length Polarity
Fixed point* four fixed decimal positions 32 bit with
8 bit with polarity none 8 bit with
16 bit with polarity none 16 bit with
32 bit with polarity none 32 bit with
8 bit without polarity none 8 bit without
16 bit without polarity none 16 bit without
32 bit without polarity none 32 bit without
* 1.0000 corresponds to an external specification of 10000, for example. The last four digits are the decimals.
Display
Use the group field Display to define parameterization settings via Keypad.
•
Use the input field Text to enter display text for the code that will be displayed on the
Keypad. The text is limited to 13 characters.
•
If the box Confirmation is activated, the SHIFT and the PRG key on the Keypad must be
pressed at the same time to accept the code value of the respective code. This setting will
not be considered for read-only codes.
– RSP
Code can only be changed when the controller is inhibited.
– PLC Stop
Code can only be changed when the PLC is stopped.
Parameterization program
Use the group field Parameterization program to enter code texts for display in GDC and the
parameter monitor.
•
One of three text options can be selected when generating the device description for GDC.
•
These entries are important for the generation of GDC description files in different national
languages.
Selection list
Select option Selection list to assign freely definable text to code values in the associated text input
field:
•
These settings will not be considered for read-only codes.
•
Complete selection lists are available for the first instances of Lenze function blocks from
libraries. These lists can be accepted, extended or modified.
•
Selection lists to be accepted by the Instance Parameter Manager can be predefined via the
Type Parameter Manager.
•
Any predefined lists used will be updated automatically if the original files (libraries, function
block POUs) were changed.
•
Changes to a predefined list will change its background colour from grey to yellow. Automatic
updates will no longer be carried out.
•
Only code values defined in the selection list can be addressed via the parameterization
environment.
