Description

There are two ways to get the status data:

From BITMAP register, read with function code 0x03, where each register bit corresponds to one boolean data. For more information, refer to BITMAP Representation of Boolean Data.
From Boolean data, read with function code 0x02.

The table lists the status data for the Modbus RTU communication.
