In case you missed that detail .. a debug node can be set to show complete msg

I hope I made it right now :pleading_face:

Hz should be 49,95 - 50,05
T2 should be 36°C
PDC2 1500-2000W
PAC2 same

44

Ok, now can you post a link to your manual that lists register 31447 as HZ value.

Never mind, found it.

So, in your linked doc...

Metering.GridMs.Hz 31447 2 U32 FIX2

it says 31447 Hz is U32 Unsigned Int 32. however, it then says FIX2 suggesting its a float.

45

its read as an int and then it needs to be divided by 100 ?

[OFF TOPIC] that would a nice feature for buffer parser to do a 'scaling' on the value for these cases

46

Same here.

Waaaaay ahead of ya :wink:

48

So the settings you need in the buffer parser are NO SWAP and use the BIG ENDIAN (be) functions...

Yes, yes, and yes...

NOTES...

  • Read the manual - especially 3.5.7 SMA Data Types and 3.5.8 SMA Data Formats
  • the idea behind grouping modbus reads & using the buffer parser and using an offset reduces comms, improves performance and simplifies data - HOWEVER you need to be aware of the data sizes, data tyes & byte offsets to get the correct value.
    e.g. if you need 30447 (SINT) & 30449 (UINT32) then read 4 items, offset 0 will have the value of 30447 and offset 4 will have the value of 30449

don´t understand - but it is the right value :thinking:

50

offset it a byte value

FIRSTLY and most importantly, MODBUS registers are 16 bit values (2x 8bits) - bear that in mind for then following info...

In this particular part, we read 52 WORDS (16 bit values) (AKA 104 bytes) starting at address item 31447

therefore...

if START ADRRESS = 31447 and we get a 16 bit value then

  • byte 0 is lower 8 bits (lo byte) of 31447
  • byte 1 is the high byte (another 8 bits) of 31447

so the next value in 31448 MUST BE...

  • byte 2 is lower 8 bits (lo byte) of 31448
  • byte 3 is the high byte (another 8 bits) or 31448

NOW - you need 32 bit values (i.e. addresses 31447 and 31448 make up the UINT32)
In other words, you need bytes 0 ~ 3 to have the correct 32 bit value.

If you make the MODBUS read an ARRAY of 52 WORDS (AKA 104 bytes) then the very last byte is in position 103

Now, you need 4 bytes to make a 32 bit value so byte 100, 101, 102 and 103 are needed - hence the offset into the byte data is 100.

START ADRRESS = 31447
address Index byte offset Reason
31447 0 0 Start address + (index * 2 bytes)
31448 1 2 Start address + (index * 2 bytes)
31449 2 4 Start address + (index * 2 bytes)
- - - -
31497 50 100 Start address + (index * 2 bytes)

Does this look familiar...

I read his explanation 5 times, but I don´t understand it 100% and the problem I got. I'm too stupid for that sorry.

The Modbus Server (Inverter) don´t like multiple simultaneous requests, than he crashs.

how can I integrade Steves solution in the "Modbus Flex Getter" i build (every 5s one request of all) ?

2 alternatives...

1...
Do the reads in series...

Where your join node connects to the multiple functions, you could replace them functions with buffer parser nodes with one entry in (zero offset) converting the ARRAY value to correct tpye

54

In the Modbus Flex Getter device configuration you can you try to increase the Queue delay ?
For example if you send the flex getter 4 messages .. the node has a built in queue that you can set its delay.

image

Also you may use the Modbus Queue Info node to monitor the queued messages. You dont need to wire this node to anyware .. but simply configure it to monitor your device.
image
and see how many messages are being handled there ?!

And what does the above value supposed to represent ?
what is the expected value ?

this ?
Metering.GridMs.A.phsA 31435 2 S32 FIX3 RO A Grid current phase L1

yes .. since you are only reading that specific value

and after, with a function, you have to divide it by 1000 to get the correct result because it says its FIX3
unless you updated to the latest version of buffer parser :wink: that has a scale option
