Functions
Refer to "<Exception Response>" (4-75) if the coil status reading command has not been performed
normally.
<Reading the Holding Register Content [03h]>
Reads the specified number of consecutive holding register contents from the specified holding
register addresses.
(Example)
•Reads the latest trip information (frequency, current, voltage at trip) from the Inverter with the slave
address "1".
•Refer to the trip status as follows:
*1.Broadcasting cannot be performed.
*2.Data is transferred by the number of data bytes. In this example, 12 ("0Ch") bytes are used since
6 pieces of holding register data are returned.
*3.Note that the holding register start address is "0011h", which is smaller by 1 than the register
number "0012h".
