It is a bit more fun to show SW as the UI on BSA starts to get operational. The diagram below is a high level draft of BSA itself and it has been saved and loaded. The tree to the left is the document showing the structure as a tree. This project consist of 3…
The storage format of BSA is a modified XML, modified for easy reading. But, it has so far been one file which will not scale if multiple persons edit a project as you end up merging a lot on XML in GIT. I am considering moving to a non-XML format, but the major issue here…
“Presentation” or “Logical/Conceptual View” is seldom added to modelling tools. The example below show a raw table with a lot of attributes, but as we use that we might want to present fake attribute or just a simplification of the raw table adapted to the current diagram. This is still the same physical table, just…
BSA is coming together, but it’s a lot of work. PLD in full effect will take some time, but the UML support is close to finish. This is the bit I miss the most myself so I will release an early version that support the UML design part. What you see below is a simple…
Minimal project box to hold a small PSU and Motherboard with 3 CAN ports. Tested a few boxes already so this will work out fine, but it is a lot of details to get right.
As we move a servo it would be more than nice to have a position feedback! The servo itself have a potentiometer telling the absolute position, but a standard Servo only have a 3 pin interface Power and Position setting – it gives no feedback. This is a common issue with many available actuators –…
Creating a module that can control a PowerServo is fine, but what about using it from BSA? What do we need to do? From a user perspective very little. In this example I just created a PLD State Diagram block with 3 input methods and one output method. It is this simple once the underlaying…
This diagram example consist of two different component types. The PLD state/event symbols have a free connection and atop-down flow, while the ComLink have 5 fixed connections in horisontal path with clear marking on where the events are. To connect you just click on the event circle and drag the mouse to the next symbol…
I have lately had the priviledge of working with two vendors of mobile, electrical vehichles – one used a self-developed system designed for volume production series, the other was a larger industrial vehiche on prototy level where they started with a standard PLC and a small cabinet. Usage of a standard PLC “kind of works”,…
This application is done manually, but I will re-generate it from BSA later. The picture shown is a classic demo application for a 9 – Valve ValvePack. You control 27 PWM signals and 13 analogue signals in this example with 9 proportional 3-Way Valves. These are quite common in subsea systems used in the oil…
