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.
Thanks a lot for you answer !
I was able to get value with raw data on BC device.
have a nice day !
Hello there,
Thanks for your awesome job !
I've a question on BC9050 :
This is my global variable:
VAR_GLOBAL Index Group Index Offset b31_DO_01 AT%QX0.0 : BOOL; 16#F031 08+0 b31_DO_02 AT%QX0.1 : BOOL; 16#F031 08+1 b31_DV_01 AT%MX10.0 : BOOL; 16#4021 108+0 b31_DV_02 AT%MX10.1 : BOOL; 16#4021 108+1 b31_DV_03 AT%MX10.2 : BOOL; 16#4021 10*8+2 i31_AV_01 AT%MB0 : INT; 16#4020 0 i31_AV_02 AT%MB2 : INT; 16#4020 2 i31_AV_03 AT%MB4 : INT; 16#4020 4
END_VAR
I'm able to get correct value on 0x4020,0,2 AND 0x4020,2,2. But i'm not able to read symbol "b31_DO_02". readAndCacheSymbols seems not listing symbols but I think it's normal ? By the way it seems that I'm not able to connect to the device without "allowHalfOpen "
Is there a way to be able to read symbol from that device ?
Thanks a lot for your support !
