Scope of the Slow Control System Remote control of several components of ICARUS-T600 detector and • environment is mandatory for: guaranteeing the proper operation conditions continuously for the entire data taking period (3 years at least); minimizing potential hardware damages by taking prompt actions; complying with the safety guidelines at Fermilab; have offline access to the history of detector conditions. Slow control means: • measure the value of operational parameters (ex. temperatures, voltages and currents, status, etc.); generate alarms (light, sound, email, sms … ) under pre-defined circumstances; take actions, such as switch on/off modules or regulate voltages, upon either manual or automatic input; log the operational parameters, alarms, actions and changes of status.
