Float Register with Modbus
« on: March 20, 2024, 06:47:41 AM »
Good morning, I am doing some Float register readings in modbus TCP and I am using the AnalogoValueDisplay with PlcAddressValue F40001. It reads correctly the float register, taking register 40002 as the most significant register (where the sign and the exponent are), I wonder how I could do it the other way round, that is, with register 40001 as the most significant register.

Thank you very much

In the Modbus driver, try to set SwapWords to True to see if that does what you want.
