This is the actual ComLink symbol with CP’s added. This component have an Auto-option allowing it to automatically open as the application start and stay open. This is often the preferred way of handling communication links in automation systems. To use this component for Modbus you need to add one or more ModbusTable and…
ComLink is as the name indicate a component that contain a communication link (IPC, Serial, Ethernet) and contain two Methods : Open and Close. In this case both are optional because the component also have an auto “AlwaysConnected” mode. The output is either OnOpen, OnClose or OnError. OnOpen is shown red because it is Mandatory…
These days we tend to work as a team through GIT or similar tools, but assuming two engineers work together on a project it would be nice to chat and see what the other is doing real-time. This feature is a bit in the future, but I like to think and plan ahead on issues…
Notes or comments are very usefully in any programming language, but they are often left out in graphical tools. BSA will add manual- and auto- created notes. Manual Notes are Cyan by default and maintained manually as part of the diagram. The example above shows a mock-up diagram with possible notes at right. I need…
Showing to different Start terminals with parameters. The result is ok and I lack a better idea. In this case I list the parameters below or right just to visualize them in the diagram. I need to add default settings here because parameters of “MyToplabel” need to have values if “MyLeftLabel” is used and vice…
It’s ca 25 years ago that I designed my first real-time plot that was a very advanced multi-plot showing a high number of sensors. I have used several plots since then, but I want to create something that is very powerfully for BSA that fullfill two requirements – (1) fast and easy to use and…
This example show a classic ER-Diagram and how to auto-generate part of an application based on that diagram. This example is actually my own Tool Maker that I use to maintain tools and properties in BSA itself. It is not auto-generated yet, but i could be and this is one of the features that I…
This is a mind experiment. The select operation will need to specify which table it shall read, and in this example I just drew the Modbus Table and used a relation between the select statement and the table. I am not sure if I want to allow this, but it is an option. Tables can…
I quickly tested using my mini-editor to edit source code and this is a mistake. The idea in this case is that you write a statement block – a small script in PScript that execute a small operation – this is intended for assign operations, but you can write a full PScript program if you…
This figure illustrate the work flow of the code generator that I decided to call “BSA Compiler”. The BSA Compiler will read the project file and compile the output source code that can be used by a standard IDE/Compiler to compile/link the target executable. The BSA Compiler will also verify project content because a lot…
