LCOS offers a basic ABS signal system that responds to block occupancy and turnout state.
ABS Signals are an advanced LCOS feature, requiring other layout objects to be configured first. To fully use the Signal system, you will need the block occupancy hardware installed for any block you want a signal to monitor.
Signal aspects are determined automatically by block occupancy and turnout state rules that you define using the Servo Manager tool. For CTC operation, automatic operation can be overridden selectively while still maintaining automatic operation of other Signals.
Signal objects report their state their to the layout every time it changes aspect. Signal messages allow a MASTER control panel to show current signal aspects.
