I have oodles of other things that I have used in the past - if I can resurrect them then I could put them in here ...
Here are just a selection for the Others category :-
PullDownMenus - A sophisticated menu system that maintained critical task access for realtime applications.
MatricesAnalyser - performed matrical operations on large an complex matrices, particularly useful for 'real' and 'imaginary' components of mathematical functions as required in Electrical and Electronic engineering.
Barmby.BAS - a QBasic program written to be the front end for a water pumping station called Barmby.
This was a QBasic program that took the output from a PLC ( Programmable Logic Controller ) and augmented it with a graphical display of the ladder. In it's day it was very useful. Typically PLC's such as OMRON C20 produced just a mnemonics list or a very poor ladder list, this program took the output from a typical PLC and created a two column display, showing both the mnemonics and the ladder side by side, as shown below :-
1 LD 1200 Start Request -1-[ ]-+-3-[\]-+-------+-4-( )-
2 OR M870 Retain !
3 AN Q992 Maintain Running conditions -2-[ ]-+
4 OUT M870 Start Motor
Notice how the numbers in the left hand column correlate with the numbers shown in the pictorial representation of the same ladder rung.
It was used on a number of projects for intermediate and final documentation. It is a shame in a way that a lot of my programs and ideas for programs have been superseded and made the final product superfluous nowadays. Maybe there are still low-budget PLC's out there that could benefit from this documentation system - If you know of any and would like a copy of the Basic program then I will send you a copy of the source code.
A QBasic program that provided 'Pull Down' menus and 'Data Entry fields' for real time environments. Real time requires that critical tasks still get processed at all times, so the standard INPUT$ couldn't be used ( for example ). Again the usefulness of this program has been superseded by the multi-threading functionality of VBasic.
This QBasic program is capable of handling large dimensional matrices with both 'real' and 'imaginary' components that makes it suitable for analysis of matrices in the Electrical / Electronic world. For more information click here -
This old system shows what I was up to in 1988 - I have chosen this because of it's ease to describe to the lay-person what real-time is all about. A top end written in QBasic for a pumping station called Barmby. The pictures below shows the test rig, where the SATT controller ( the PLC on the left ) is provided with inputs and the QBasic program residing on the PC is extracting information from the PLC and providing a front end for the operator.
The menu system as described above in the 'PullDownMenus' section was used to provide the core coding, allowing alarm monitoring and essential control to continue during data entry.
Again this is old hat and the technology has been superseded, but at the time it was at the forefront of the technology. Click here
if you want to see the software. NOTE - The trend displayed on the screen in the right hand photograph - the information for this trend was sourced by the QBasic package and displayed via the QBasic package. If you are familiar with AFE then you'll recognise the similarity of the display ( with the alarms being shown at the bottom of the screen - 'Unacknowledged' ones with a red background. ).
