Är det bra eller dåligt att ABB 800xA är relativt nedlåst?
Vilka funktioner saknas?
För mig så väger nog nackdelarna mer än fördelarna, dvs risken att peta i systemet är för stort.
Men det är kul att knappra kod
Why I should use C#?
Before we start to explain how to create Graphic Primitives in C# we should clarify why we do so.
PG2 is a well done, very powerful graphic system made by ABB. We can display nearly anything with buildin functions.
But there are rare cases where there are still limitations. Want some examples?
- It is not possible to build "loops" with variables.
- Is is not possible to get properties from Objects to variables. (To calculate the position of one Object from multiple others)
- It is not possible to use advanced input controls (like Mouse Wheel...)
- It is not possible to connect to external resources like SQL servers, etc.
- It is not possible to Control Windows resources from inside the Graphics.
- All this is possible (and many more...) with C#.
Nice, but whats the drawbacks?
There are many reasons for not using this possibility.
- There is no support from ABB. If something is going wrong, ABB can blame your Graphic Primitive for everything.
- You have to test and upgrade your Graphic Primitive on every 800xA update. ABB does not promise stable (in sense of not changing) interfaces for the PG2 implementation.
- You have to deploy your Graphic Primitive by yourself. There is no System Installer support.
- Graphic Primitives have to be digital signed with an specific ABB key. Of course we do not have this signature key, so have two options
- Enable Signature Bypassing for your Primitive. This is a possible security weakness.
- Ask ABB for signing your Primitive. I have no idea if they do this at all. Not my cup of tea, thats business.
