Application Notes
Once you have made these settings, you can go into the other three tabs and create the ‘tags’
that you wish to portray to the DCS/SCADA system. These include instantaneous readings and
averages (represented as registers) or digital inputs (represented as coils).
Click in the
*
section at the bottom of the screen to add a new tag:
The scaling factor is only used when the default register format is set to 16-bit integers,
otherwise it is ignored / does not need to be set. The scaling factor is used to convert values
to integers (and the appropriate logic will need to be set on the DCS/SCADA end as well):
Integer Value = Floating Point Value / Scaling Factor
.
Thus, a scaling factor of 0.01 will convert a value of 1.23 into integer ‘123’. Values are rounded.
