Communication Measure in Counts
With ZIVercomPlus program is possible to define the Full Scale Range that is desired to transmit each magnitude in
counts. Parameters necessary to configure the Mathematical expression are:
- Offset: A number indicating the compensation of de Magnitude.
- Limit: it's the Maximum value of magnitude
- Max Communication: it's a constant that depend of the Number Bits of Analog Input.
Max Communication=2**(Number Bits Analog Input - 1)
For 16-Bit Analog Input (Obj 30 Var. 2)
For 32-Bit Analog Input (Obj 30 Var. 1)
- Rated value: Nominal Value of the
- Nominal Flag: This flag defines if the limit is proportional to the rated value of the magnitude.
- TR: Secondary to Primary Transformation Ratio.
Mathematical expression to describe the Full Scale Range is:

Communication Measure in Engineering Units
With ZIVercomPlus program also it's possible to transmit each magnitude in Engineering Units. Parameters
necessary to configure the Mathematical expression are:
- Offset: A number indicating the compensation of de magnitude.
- Limit: it's the Maximum value of magnitude range.
- Rated value: Nominal Value of the magnitude.
- 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.
- TR: Secondary to Primary Transformation Ratio.
- Scaling Factor: Multiply Factor of magnitude.
