Did you press the "read next address" until it got down to 50?

show me a screen shot.

please dont take any short cuts - please do as I ask.

@Steve-Mcl  
i tried it all way but i get the data when it come to 62

 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/7/d/7d9569d2cb05371b5534259f030bc65a178e8792.png)  
in this image i started from 70 and then it was showing data on 62, why i tried from 70 because i was confused a bit from starting 100 there were only timeout error

@Steve-Mcl  
I got it but the thing is would i need to sort the address list  
first screenshot  
for debug PLC data 1

Good, so now you have 100 data items read in 2 chunks, all nicely assembled into a singe object.

Now if you want X, Y and M values, tell me what they are in a list like this...

| Address | Name |
| --- | --- |
| Y4 | powerOn |
| Y5 | machineReady |
| Y9 | inCycle |
| M22 | overCycle |
| etc | etc |
| etc | etc |
| etc | etc |

No, it contains the items specified in the Buffer Parser.

If you WANT 100 items, you will have to include them in the Buffer Parser like I did.

I did a selection for demonstration purposes.

I cannot do everything for you. I have given you the knowledge, you will have to do some things yourself.

Yes i know that you helped me a lot with a real example thank you for that no doubt the other thing i have to do.

i need to know that how to find bytes offset and index offset

Do you know what a 16 bit value is?

Do you know what a BYTE is?

1 MC READ value is 16 bit AKA 2 bytes.

therefore:

- If you get 3 16bit values ` [xxxx, yyyy, zzzz]` then `xxxx` is bytes 0 & 1, `yyyy` is bytes 2 & 3, and so on.
- if you read D990,50, then D990 is byte 0 & 1, D991 is bytes 2 & 3 ... D1024 is bytes 68 & 69, and so on.
- if you read D1040,50, then D1040 is byte 0 & 1, D1041 is bytes 2 & 3 ... and so on.

It is simple maths.

Byte Offset = (Address - Start Address) \* 2

e.g.  
Address: `D1048`  
Start Address: `D1040`  
Byte Offset = `(1048 - 1040) * 2` = `16`

Read this again:

> That said, i can see you have entered the address `D990`. That will READ only 1 WORD of data!. How do you expect to parse things like `temperatureSetting` which is at D993?

> 1. You want to READ from the PLC many things at once to make your code easier to maintain, get best performance, get good consistent data
> 2. So we read 99 16 bit integers starting from D990
> 3. Remember, D registers are 16 bit AKA 2 bytes wide
> 4. That means D990 value is at index `0` (offset byte `0`)
> 5. That means D991 value is at index `1` (offset byte `2`)
> 6. That means D992 value is at index `2` (offset byte `4`)
> 7. That means D993 value is at index `3` (offset byte `6`)

@Jayeshpitale1

I am going to leave you to do this by yourself now.

I have spent over 4 hours of my own personal time, across the last few days helping you - I think that is enough.

I have given you a LOT of demos, a LOT of information and enough tips and hints to put this all together by yourself.

Best of luck. Steve.

i got it Both the thing are in one D tag and Y tag address

 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/9/1/91c46037744863a4a4e61721da87122d22239ea1.png)

Now what about D\_bit Address Means it is show Boolean in Kep and when i add it to MC protocol a single address i need to use Like this D1088.2 for D\_bit 108802

Add a BOOL as i have explained twice already

Here is it one last time.

Calculate the offset to the DM, enter the BIT number, give it a name
