SyntaxMembers| Member name | Value | Description |
|---|---|---|
| Unsigned | 0 | Publishes power factor magnitude only, |P| / |S|, range [0, 1]. |
| Lagging | 1 | Positive sign indicates a lagging (inductive) load, Q > 0; negative sign indicates a leading (capacitive) load. |
| Leading | 2 | Positive sign indicates a leading (capacitive) load, Q < 0; negative sign indicates a lagging (inductive) load. |
RemarksPower factor magnitude is always defined as |P| / |S| in the range [0, 1]. The sign convention determines how reactive power direction (Q) is encoded into the published value:
- Unsigned publishes the magnitude only — values are in [0, 1].
- Lagging publishes a positive value when reactive power is consumed (inductive, Q > 0) and a negative value when reactive power is supplied (capacitive, Q < 0) — values are in [-1, +1].
- Leading inverts the Lagging convention: positive when capacitive (Q < 0), negative when inductive (Q > 0) — values are in [-1, +1].
