Basic Program (Input)
Basic Programs can be used as either Inputs, Outputs, or Network Programs. Basic Programs
available to be used as Inputs will be selectable from within the Select Input menus. If no Basic
programs have been installed or selected as Input programs, the Basic Programs group will not be
shown in the Select Input menu.
The above screen shows a Basic Program with the name H-3531 Flashlite that is being used as an
Input for a Task. If a Basic Program does not have a name declared, the program’s filename (e.g.
rs232Sensor.bas) will be used as the program name and title of the Properties screen.
Program: The Basic Program can be viewed or debugged using the View and Debug buttons. It
is a good idea to test (Debug) each Basic program before enabling scanning to verify the program
will run as expected.
Any special variables, known as Symbols, within the Basic Program will be listed in the
Variable’s box. These variables can be modified individually for each Task by using the Edit
Value button, allowing the same Program to be used in different circumstances, if desired.
More information regarding Basic can be found in Chapter 7 of this manual as well as within the
Basic 5000 User Manual, downloadable from the waterlog.com web site.
If the Program saves a value to the calling Task, the Test button may be used to retrieve the
Value determined by the Program. If a value is not found, No Value will be displayed.
Math & Data Options are not available for use with Basic Programs.
