3.7: Type F7 Secondary Voltage, Current, VA, VAR, Watts, Hz or Flicker

Length: 2 Registers (4 bytes)

Range: +32767 / -32768

Unit: 1/65536 V, A, VA, VAR, W or Hz

The registers together contain a four-byte signed (2's compliment) integer. Positive values have the most significant bit clear, and have the same magnitude as an unsigned integer. Negative values have the most significant bit set. The magnitude of a negative value is found by complimenting (inverting) all of the bits and adding 1.

Example:

Registers 00153 – 00154, Tenth second Phase A VAR might contain the following data:
