Data may generally be viewed relative to its source in addition to a global system wide view. Data from I/O points may be viewed under the I/O Devices tab. Data from Modbus registers may be viewed under one or more Modbus tabs, etc. The following illustration shows analog input data. Note that for physical I/O points, the data is displayed in both integer and floating point form.

Raw data from local I/O is stored in the integer registers. Scaled data is stored in the corresponding floating point registers. Integer registers are numbered 1 to 999. Floating point registers are numbered from 1001 to 1999 and are allocated 2 registers per floating point value consistent with Modbus practice. The first 10 of each data type are reserved for physical I/O on i.Board. The number of reserved registers vary in other models according to the number of physical points.
