With ZIVercomPlus
program it's possible to define the Full Scale Range that is desired to transmit each
magnitude in counts, which is the unit used by the protocol. There are three parameters to determine the distance
range covered:
- Offset: minimum value of each magnitude to transmit 0 counts.
Limit: it's the length of the magnitude range used to calculate the number of counts to transmit. If offset is 0,
-
same as the value of the magnitude for which the maximum number of counts defined by the protocol is sent
(32767 counts).
- Nominal Flag: this flag defines if the limit is proportional to the rated value of the magnitude or not. The rated
value of the new magnitudes defined by the user is a setting, while for the pre-defined magnitudes is a fix
value.
Mathematical expression to describe the Full Scale Range is:

 Deadbands
Deadbands are used for configuring Analog Input Change objects (Object 32).
A Deadband is defined as a percentage over the Full Scale Range (FSR).
The Deadband can be adjusted to the device by means of MMI (Man-Machine Interface or front-panel user interface),
between 0.00% and 100.00%, in steps of 0.01%. Default value is 100.00%, meaning that generation of Analog
Change Events is DISABLED for that input. There is an independent setting for each Analog Input.
 Energy counters
The range for the energy counters in primary values is from 100wh/varh to 99999Mwh/Mvarh, and
these are the values transmitted by protocol.
