BREAKER_PANEL_MON
Panelboard summary: closed, open and tripped pole counts from bit-coded position words, plus main loading.
When to use it
Use BREAKER_PANEL_MON when a panelboard with up to 64 poles reports each breaker's position and trip flag as bits of a status word, and the site needs a summary it can alarm on rather than 64 individual tags.
Interface
The published port signature. This is the whole of what the block exposes to your program — the implementation body is not shown here and ships with the download.

Supervised control write
BREAKER_PANEL_MON commands a real actuator. It is written to sit underneath your own interlock, permissive and protection logic — not to replace it. Commission it as you would any control block you wrote yourself.
