Read symbol value on BC9050 about ads-client HOT 2 CLOSED

Hi, thanks a lot! :)

First, it might be that the BC9050 has no symbol information available. At least I have that kind of feeling as it's very simple device. If that is so, then only way is to read using raw addresses.

However, there is at least one error in your code. As the BC9050 is TwinCAT 2, the variable under a GVL needs to have dot (.) beforehand. See https://github.com/jisotalo/ads-client#important-things-to-know-when-using-with-twincat-2

So instead of
var symb = await client.readSymbol('b31_DO_02')
use
var symb = await client.readSymbol('.b31_DO_02') (notice the dot).

However, it might still not work because of the BC device.
