Issue
Converting IEEE float to decimal
Product Line
Modbus Tester
Environment
Modbus register conversion
Cause
When using Modbus Tester to read a 32 bit register, the two 16 bit registers need to be converted in order to see the actual value.
Below is an example of reading 32 bit Input Registers:
Resolution
A converter such as https://babbage.cs.qc.cuny.edu/IEEE-754.old/32bit.html can be used.
The two hex values in each of the 16 bit registers are placed together to obtain the decimal value:
Modscan was used to validate the results:
