FP.zip --> Standard command set
FPX.zip--> Extended command set

The main objective of these examples is to demonstrate how to use Visual Basic 
to communicate with FieldPoint. 

These Visual Basic 5.0 examples have been written to the following specifications. 
They communicate to the FieldPoint stack through serial port 1 (COM1) using the 
STANDARD and EXTENDED command sets. The FP.zip has files which implement the 
standard command set, and FPX.zip has files which implement the extended command 
set. They use Component Works controls and indicators on the front panel. If you 
do not have Component Works you can download a demo from our web site.  Otherwise 
simply replace these user interface controls with others you have. 

These are very simple programs, error checking is not performed on the returned 
data. Obviously, error checking would be required in an application scenario.  All 
commands can be found in the FieldPoint FP-1000 and FP-1001 Programmer Reference 
Manual; page numbers are cited in the comments.

The module addresses used in these programs correspond to the hardware layout as 
follows: FP-1000 (or 1001), FP-AI-110@1, FP-AO-200@2, FP-DO-400@3. The comm settings 
used are 115200 baud, no parity, 8 data, and 1 stop bit. It is also assumed here that 
the first output channel of the AO-200 is wired to the first channel of AI-110. This 
way we can use the Knob to write to AO module and read this back from AI module. The 
range on both the modules is 0-21mA.
