5.2.6
RTD IPSO Definition
The RTD sensor IPSO definition provides signal range, measured min/max values, IPSO object type information. The
Min / Max range values depend on the type of RTD.

5.3 Digital Input / Output Interface
The DIO Interface provides 2 digital inputs which are hardwired to the Digital outputs. These may be used to detect the
state of external switches (output off) or to monitor the state of the outputs. The DIO Input descriptor is at base addresses
0x0068.
