Causes of run-time errors for the numeric input cursor point

At run time the application logs errors about the cursor point to diagnostics under these circumstances:

Unassigned connections

If the Value connection is not assigned, when the operator activates the numeric input cursor point, the pop-up is not shown and the application logs an error.

Terminal resolution too small

If the computer's resolution is too small to display the numeric pop-up keypad or scratchpad, the pop-up is not shown and the application logs an error.

  • If the terminal's resolution is smaller than 124 pixels wide by 240 pixels high, the numeric pop-up keypad cannot open.
  • If the terminal's resolution is smaller than 124 pixels wide by 68 pixels high, the numeric pop-up scratchpad cannot open.

Ramped value outside minimum and maximum range

If ramping the value either up or down using a key button or a cursor key, causes the value to be greater than the Maximum value or less than the Minimum value (set in the Numeric tab):

  • The application logs an error.
  • Nothing is written to the Value connection.
  • The numeric input cursor point will stop ramping until the key button or cursor key has been released and pressed again. Therefore the error will not continue to be logged repeatedly in auto-repeat mode.
