Interface registers 

These registers are the recommended registers to use for extracting the basic signals from the trans-
mitter via Modbus. The advantage of using these registers is that multi-register Modbus commands can 
be used to make the interface more efficient. 

A control or status register contains 32 bits of on or off information. When one of these registers is 
displayed, a bit is selected by using the left and right arrow keys.
