<Reading Holding Register Content [03h]>
Reads consecutively the specified number of holding register contents from the specified holding
register address.
(Example)
Read past trip data from the Inverter with slave address 5.
Below is the data on past three trips:
Read the data received in response, as follows:
If the holding register content has not been read out normally, refer to the "Exception Response"
section.
