ScreenViewer 3.2
Product Specification RobotWare for BaseWare OS 3.2 29
Advanced Display functions
The user defined screens run independently of the RAPID programs.
Some events occur on a screen (new screen displayed, menu choice selected, function
key pressed, field modified, ...). A list of user screen commands can be associated with
any of these events, then when the event occurs, the command list will be executed.
A screen event can occur
- When a new screen is displayed (to initialize the screen contents).
- After a chosen interval (to refresh a screen).
- When a menu choice or a function key is selected (to execute a specific action,
or change the screen).
- When a new value is entered in a field, or when a new field is selected (to exe-
cute some specific action).
The commands that can be executed on screen events are
- Reading/writing RAPID or I/O data.
- Reading/writing fields contents.
- Arithmetical (+, -, /, *, div) or logical (AND, OR, NOT, XOR) operations on
the data read.
- Comparing data read (=, <, >) and carrying out a command or not, depending
on the comparison result.
- Displaying a different screen.
Capacities
The user screens can be grouped in a screen package file under a specific name. Up to
8 packages can be loaded at the same time.
A certain amount of memory (approx. 50 kbytes) is reserved for loading these screen
packages.
- The screen package to be displayed is selected using the far right hand menu
“View” (which shows a list of the screen packages installed).
