Hello,
I am trying to write a Labview program to read a temperature control.
It uses Modbus-ASCII. Sadly I do not complete understand the
"Communication Register" included in the instruction.
It tells me the function code: 03H to read the contents of register, 06H to write one word into register, 02H to read the bits data, 05H to write one bit into register. Secondary there is a list with the address and content of Data Register, for example 1000H belongs to the process value and 1001H to the set point.
My input strings to read the process value/ set point were:
:07031000 getting the answer: :0783096D
and :07021001 getting the answer: :0782096E
(The Controller Address was 7.)
I do not know, what the answer means or where the temperature will be indicated.
I am happy for any help, comments and ideas.
Thank you!
