PANTO_BUS_CHARGE
Pantograph opportunity-charging sequence: docking handshake, proven isolation, ramped power transfer and a proven-open release.
When to use it
Use PANTO_BUS_CHARGE when an overhead mast or roof-mounted pantograph charges a bus or truck automatically during a layover, and the contact must never be made or broken while current is flowing.
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
PANTO_BUS_CHARGE 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.
