Invalid Modbus Data Format

¿Qué significa #03 ?

The Destination Device (inverter) reported that the data specified in the Modbus command is in an unacceptable format. This can occur when writing data that does not conform to the expected data type, length, or structure for the target register, resulting in the inverter rejecting the data.

• The data provided for writing to a register (e.g., in 'Write to Holding Register' function) does not match the expected format or data type of the inverter's register.
• The number of data bytes or words specified in the Modbus command is incorrect for the target register or coil.
