I am getting closer to finishing a Beta version of BSA as a pure Modeling tool. It helped a lot starting to use BSA on a PLC project and the visual dictionary UI is a step in the correct direction. What you see below is one of my remaining bugs. I removed connection points after…
The Dictionary part of BSA is quite important as your project grows because it is instrumental in keeping overview and re-using components. The content is always the same, but I decided that I needed at least two precentations of the Dictionary content that is selectable by buttons on top of the Dictionary folder itself. You…
BSA contains a build-in component “Communication Link” and I wanted to see how it would be to code this manually in BSA. As you code you can chose to code modules in target language , or you can code components in BSA itself as we do in this example. See discussion below the diagram. In…
I am using BSA myself daily as we speak and this sometimes makes it very obvious that some of the functionality needs to be improved. I was initially very happy with my Property Editor (at right), but as I have worked on large 4K screens I have noticed that text gets very small and hidden…
I created a simple Hello World diagram (below), saved it, Imported it to itself and made a copy/paste – so below I have 2 x Module 1, 2 x Diagram 1 and 3 x Hello World. This is just an integrity check on the drawing engine as the engine uses an unique reference and not…
I have started to add four functions “Import, Cut, Copy and Paste”, The example below import a copy of the existing module into the repository. The main challenge to maintain integrity is straight forward as integrity is based on a unique, internal reference that needs to be updated. Names are only a precentation on this…
SDL (Specification and Description Language) was at one point considered as a UML diagram add-on, but UML went in a different direction. I am used to SDL from Telecom and use an abstracted version (simplified) because I liked the state engine concept added to normal flow charts – so why did I bother with UML…
Changing UML State is straight forward – just use ToolMake to add a new property and change the default settings + a few lines of code to add the header change I also added. This is a compromise on my earlier Connection Point – I decided to change the default to Free and implement Free…
I wanted to draw some simple, high level UML State diagrams using PLD and while it worked I also used far more time than I expected. This was in many ways a big failure with regards to the objectives I have set, so I need to do some re-thinking. In this first diagram I use…
The UML State Diagram below illustrates an Actuator that regulate on Position, Speed and Torque, but is input data here Events, Data or both? Also the diagram show event name three times. In this case the gray names should be hidden as the Start Terminal carry the event name. I am not sure I need…
