End Debug
This command removes the APOSS-IDE and the controller from "debug" mode.
Watch Add / Start / Stop
This function enables online monitoring of the
variables, arrays, system and axis processing data
and axis parameters.
All values currently being watched are maintained in
the Watch Window in the bottom-left corner of the
APOSS Window. New values can be added to this list
using Development → Watch Add. Existing values
can be removed from the list by clicking on the
value and then pressing the Delete keyboard key.
In the Watch Add dialog all program variables and
arrays are shown on the left and all system values
are shown (in a tree) on the right. Add a value to
the Watch Window by clicking on it, selecting the
format to be used to display the value, and then
pressing the Add button. Values can also be added
simply by double-clicking on the value. Multiple
values can be added before closing the dialog.
If an array value is being added to the Watch Window, then the array indices must be specified. These fields
will be disabled if the selected value is not an array. Note that only the first 250 elements of an array can be
watched.
Activate and stop the monitoring with → Watch Start, → Watch Stop or click
NB!:
When monitoring is active, the Watch Window is updated constantly. This consumes both controller
resources and network connection resources. Hence, the number of values being watched should
be limited to a reasonable number (usually, not more than 10-15 values, depending on network
connection speed). If more values than this are required, then the Oscilloscope should be used.
Syntax Check [F4]
Clicking on Development → Syntax Check will do a "test compile" of the program being edited. This can be
a useful function to use while creating new programs or modifying existing programs. It is a quick way to
find syntax errors in the program without having to download the program to the controller and execute it.
If a syntax error is found, then the line number and an error description are displayed in the Communica-
tions Window and the cursor is automatically placed at the position of the error.
The Syntax Check produces a debug file in addition to checking the syntax. This file will have that same
name as the program but with the file extension ".ad$".
