- Show a small screenshot of how you configured the MC READ
- Try reading
D990- does that timeout or does it return a value?
@Steve-Mcl
i set MC protocol node to D990,99 and it give me timeout error as a result it did
not worked
and the code i mention about is i removed ,99 from it and it worked for MC Protocol node but for buffer it say "Error: data is not an array or a buffer"
I need to see a small screenshot of how you configured the MC READ for D990,99
Please set it again & operate it.
Also set the debug node to show the complete message. Include that in your screenshot.
Please clear the debug output
Please set the "Output Format" to Array on the MC READ
Please set the debug node to "show complete message"
Please press the inject again
Please send another screenshot with the debug msg expanded
After Doing it it still shows me Timeout error

@Steve-Mcl
above code has the changes you showed me please refer
Sorry, but if you are not going to do what I ask, I cannot help you any more.
@Steve-Mcl
i did it
Now try adjusting the count.
Try D990,50 - does that work?
Try D990,30 - does that work?
Try D990,9 - does that work?
Yes, that is expected because of small data READ size!
Lets figure out READing the higher addresses first.
Good. Now lets try reading a single D from higher up.
For now, until we understand what is happening, DELETE the wire from MC READ ---x---> Buffer Parser node
Next, please answer every question...
- What do you get for address
D1023 - What do you get for address

Where to find it in this message
No, please do what I asked.
- What do you get when you set MC READ to READ ONLY 1 address -
D1023 - What do you get when you set MC READ to READ ONLY 1 address -
D1024 - What do you get when you set MC READ to READ ONLY 1 address -

D1087 - What do you get when you set MC READ to READ ONLY 1 address -
D1088
By the way, that data HAS 50 elements but you said...
So did D990,50 actually work OK?

@Steve-Mcl
As we are discussing on D tag Address
i still dont under stand how we would get D_bit and M and Y in this or would i have to create a different node for them
Good.
Now, we need to find the max read size. 99 should work but as it doesnt, try lowering it until it works.
- Try setting MC READ to D990,98 - does it work?
- Try setting MC READ to D990,97 - does it work?
- Try setting MC READ to D990,96 - does it work?
- etc etc etc
Tell me the highest ,nn count number that works.
To make this easier - use this flow:

I have explained that before here:
and i WILL explain it again - AFTER we get reliable data for the "D" area working
@Steve-Mcl
Now i gave you the answer of the question you asked before can you please tell what next to do
Means i need the data in the form of
for example
address D990
topic Extrusion
Payload 300
address D992
topic : temp
Payload 450
Yes, I will tell you how to acheive that but you are jumping ahead.
please answer
