Steve,

Fisrt I do not have time to read this huge documentaion and try to figure all out however a quick scan raised some points with me
as below it seems the devise sends out 4 bytes when you read the at address 0x006/007 as one and secondly it looks like the data is already in Floatpoint form,

You need to look at the Readregister function and debug what this function is reading from the Devicse if you read or interpret the data received wrong you will never see the problem also the getResponce macro's you must debug to see what they contain

I think the long variable that you use for the RegisterRead macro is the wrong choice I would start with this macro and debug what is received in it and make may way out with getResponce macros and determine what is in each variable

may be Ben has a magic answer for you

Hope you come right

Playing with your Logged Data I am sure now that the response is in Float .

your log writing and reading address 0x06

the meter answer with 43 70 28 F6 which is 240.16V
Converting the 4 bytes as the manual show to float get the correct response

I think with out having the instrument you should read the 4 bytes and use the conversion component to get the float value

I hope this helps

just use the TypeConversion macro to get you the float from 4 bytes

Curious did you get this topic going now ?

There is a great example here.

Afternoon All,

Getting mixed responses from the console when trying to view the modbus data ?

Sometimes when i run i get text in a blue text color - see console 1 (attached)
The next time i run without changing anything i can get a reply for 3 attempts then nothing - time outs

Any idea's to what is happening ?

Regards

Steve
