Explanation of Each Function Code
<Reading Coil Status [01h]>
Reads out the coil status (ON/OFF).
(Example)
Read multi-function input terminals S1 to S6 on the Inverter with slave address 8.
Refer to the following table for the multi-function input terminal status.
The data received as the response shows the status of coils 7 to 14. The data received here, "17h
= 00010111b", should be read with coil 7 as LSB, as follows:
If the read coil exceeds the defined coil range in the final coil data, such coil data is regarded as "0"
and sent.
If the coil status reading command has not been performed normally, refer to the "Exception
Response" section.
