This document sets out the requirements and suggested implementation of the Local Controllers for the ATLAS Level 1 Calorimeter Trigger [1].
The Run Control [2] package of the ATLAS Online Software
[3] establishes the concept of a Local Controller.
This is a software component responsible for implementing the state
transitions required to bring a well defined part of the ATLAS
readout system from the initial, powered on state into the running
state (and back).
