SETBUSY Function
Enables/Disables the system busy state. When SETBUSY is set to true, the status light will change to red and all user interactions are ignored.
Syntax
SETBUSY(fState)
Parameters
|
fState |
Required. A boolean value that indicates whether the system should go into the busy state. |
Return Value
None
Remarks
Setting SETBUSY(true) indicates that:
- The system is busy doing something
- Things the user does should be ignored while the system is busy.
- There is nothing the user can or should do to release the busy state - it will be released automatically when the busy activity completes.
It should not be enabled when interaction is required from the user.
If a script sets busy to true, it should ensure that it is set to false after the processing is finished. Otherwise the user will not be able to interact with the aXes screen.
Example
Turn off the busy state to allow user interaction, and indicate that the system is not busy
SETBUSY(false);
Turn on the busy state to ignore user interaction, and indicate that the system is busy
SETBUSY(true);
