This simple drawing illustrate how I can create a gauge with several separate layers. In this case I draw a background and a needle on top of that. The final gauge is illustrated at top. This is exacly how I plan to embed a gauge editor in BSA – by using a table with x…
This example is a valid Plain Logic Diagram. Since the start and exit symbols are drawn on the same diagram this will count as a single diagram then it is re-used. It will be a block with 3 entry points and 3 possible events. Ignore the fact that Start3 and Exit3 is a separate diagram…
This is just an auto-generated demo (new application) using Visual Studio/MFC. I use Visual Studio Community so you can download this and try for yourself. I switched from DOS to Windows back in early 90’s using Windows SDK and C at first – I remember the day I got my hands on Visual C++ 1.0…
Setting up all the colors needed for controls is actually a bit of job because you need a set of colors for (1) Normal display, (2) Mouse Hover, (3) different states. In this case I show a button so I need Pressed. And for each set I need background, text and border etc. So, if…
My previous entry raised the issue about how to edit multi-line text. The illustrations below show one possibility. In this case I illustrate a description – something I want on every object. This is a normal property, but since it is a multi-line text it servers little purpose to display it on a few characters…
This shows the Note – the Note is a tool allowing you to write text with a Note border around it and it can be linked to obkects with lines etc – a handy way to make comments. However – how do we edit the note? (1) display the full note, while (2) display the…
Don’t worry – you will hear a lot about the Property Editor. The one you see above is yet a simple one. I am still using string edit for colors, but it works fine due to the nature of JavaScript. JavaScript accept colors in string format by name or #xxxxxxxx. (ARGB format). I will add…
I am reaching a point where my illustrations regarding BSA are more and more the real thing. Property Editor is now real so I can start edit the components and add properties. I have a few days work setting up correct properties and then I will deal with saving and loading projects and a few…
A critical component for a HMI Frontend is “Data Source”, meaning where is data loaded and saver. HMI alone is worthless unless it is actually connected to something. This can be a remote Modbus device, a database, simple memory structure, file structures etc. BSA will provide the component, but the user must add the source…
Yet Another Fake Diagram. The symbols are real, but the links between the symbols are fakes yet… give me a few days. But, the fun is that I have reached a point where it is easier to make illustrations using BSA than Powerpoint. The illustration show a classic sub-diagram – you have a state symbol…
