Local Logic Variable Table
The VersaPro programming environment includes a window that contains the Local Logic
Variables. The table has several tabs that break the variables up by category. The categories are:
•
Axis 1 – Variables specific to axis number one
•
Axis 2 – Variables specific to axis number two
•
Axis 3 – Variables specific to axis number three
•
Axis 4 – Variables specific to axis number four
•
Global – Global data such as Module Status Code
•
CTL bits – DSM general purpose control/status bits
•
Parameter Registers - DSM Parameter data
The table allows the user to drag and drop or cut and paste the text from the table into a program.
(Reference Figure 10-7)
Figure 10-7. Local Logic Variable View Table
The table has six columns. The columns are as follows:
•
Name
– This column contains the variable name that is valid to be used within a local logic
program
•
Type
– This is the data type for this variable. For example 32 Bits means that this variable is a
32 bit variable.
•
Group
– This is the group this variable is placed in. For example, FacePlate I/O means that
this variable refers to a point on the module faceplate.
•
Description
– This column contains a textual description of the variable. If the user hovers the
mouse pointer over the description a tool tip will be generated that allows the user too easily
read the description.
•
R
– This column indicates if the variable can be Read by a Local Logic program
•
W
- This column indicates if the variable can be Written by a Local Logic program
