REMUS is a Supervision, Control and Data Acquisition system (SCADA), able to monitor and control organizations’ impact on their environment. It has been developed by CERN HSE Unit, who is in charge of providing Radiation Protection and Environmental Impact Monitoring to CERN facilities and immediate surroundings. REMUS took advantage of more than 30 years of experience providing safety systems to CERN. It is based on Siemens WinCC Open Architecture.

REMUS provides a unified way to supervise and continuously operate heterogeneous types of instrumentation. It currently offers out-of-the-box interfacing to more than 75 device types and provides software tools easing the integration of new ones, in a time and cost effective way.

REMUS provides the following functionalities:

  • Data acquisition and archiving of measurements and events coming from the instrumentation.
  • Display of near real-time measurements, alarms and operational states of instrumentation through customisable user interfaces composed of synoptic, widgets and alarm screens.
  • Remote sending of commands and operational parameters to the instrumentation.
  • Display of archived and near real-time measurements and events coming from the instrumentation, through a data visualisation tool, ERGO (Environment and Radiation Graphic Observer).
  • Publishing of archived and near real-time measurements to external systems.
  • Run-time installation of new instrumentation.

REMUS at CERN is used by more than 200 users (CERN Control Centre, RP & Environmental Experts, Fire Brigade, …), providing 600 synoptic screens, 50,000 remotely controlled parameters, 3,200 data streams and archiving 100,000,000 measurements every day.

REMUS has been designed to be as scalable and adaptable as possible, allowing its installation in a different environment than CERN, in a few days.



Advantages & Applications


  • Environmental and radiation monitoring of any facilities.
  • Integration of heterogeneous instrumentation in a centralized and distributed supervisory system.
