Serial Interface

The register address are as follows:
40900 to 40934-floating
40936,40937,40938-8 bit integer
40939 to 40949-floating

Tried the following things:
1:Configured 3 datasets as per this list but datasets went bad
2:Configured 40900 to 40936 as floating-dataset 1 became healthy and got proper data for these registers,dataset 2 also became healthy,but dataset 3 still bad
3:Configured 3rd dataset as 40939 to 40949 as floating but they were bad(Diagnostic status-error response-installed resp msg size)
4:Configured from 40940 to 40950 as floating & datasets turned healthy however received junk data


(No 3rd party vendor available for support,no serial cable present to test with modsim)

What could be the issue and how to resolve

  • Hello,

    What are you trying to connect to? Are you using a serial card, or is this Modbus TCP?

    Other things to consider: Are you sure that your data map is correct? Do actual registers exist here? Are they truly 32-bit floats or are they 2x16 bit integers? Can you attempt 1 register at a time?
