It seems that I cannot read a float value corectly from a holding register.
The float value is on 2 * 16 bit registers.
I have tried every modbus tricks:
- +/- 1 bit shifting (0/1-based addressing)
- use of HRUI or HRF
Reading integer value is ok (that fixed me about the last two points).
Since the Modbus slave has been developped from scratch, I was wondering if the correct standard was used to store float values.
Does anyone know the expected float format when reading from a holding register with Ignition ModbusTCP driver?
Thanks in advance.
