Logic relay

Entity description

A message forwarder. Fires an OnTrigger output when triggered, and can be disabled to prevent forwarding outputs.

Useful as an intermediary between one entity and another for turning on or off an I/O connection, or as a container for holding a set of outputs that can be triggered from multiple places. Additionally, its Enabled/Disabled state can be used for conditional logic ("if, then" style logic).
