Func
tions
*1. Broadcasting cannot be performed.
*2. When specifying the value for 0 or over 32 of the reading coils, the error code "03h" is replied.
*3. Data is transferred by the number of data bytes.
The data received as the response shows the statuses of coils 7 to 14. The data received here, "P7h
= 00010111b", should be read with coil 7 as LSB, as follows:
If the reading coil exceeds the defined coil range in the final coil data, such coil data is regarded as
"0" and sent.
Refer to "<Exception Response>" (page 4-74) 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 reg-
ister addresses.
(Example)
Read the factors on the past three trips from the Inverter with slave address 5.
Below are the data on past three trips:
