LocoNet Slot Monitor

The Slot Monitor tool displays a table of the "command station slots'" contents. Slots are used to control individual locomotives and consists. The display includes the decoder's speed step format, current speed and function settings, consist information and status. You can choose to show either all slots or just the ones being actively used.

The checkboxes at the top allow you to show just the active (in use) slots, or all locomotive slots. You can also choose whether to show the "system" slots which don't carry locomotive information.
The "Estop All" button sets the speed of all the locomotives to "Emergency Stop" in one action.
The "Release all unused slots" button (not visible in this screen shot) will reclaim extra slots in the Command Station.
