Introduction

The DCS and interlock in ATLAS:

  • permit coherent and safe operation of ATLAS → FSM for well-defined operational procedures and automatic actions

  • continuously monitor and archive the operational parameters

  • power and control of the detector hardware → commands and error handling

DCS and interlock for module reception

The old setup for DCS and interlock are documented here: DCS Control/Monitoring for Inner Pixel Integration

Module reception areas are updated to ANL box as shown in the figures, details about test setup are documented in Kim Doyeong's slides.

Grafana pages are used to monitor the module temperature, input voltage.

(For Nathan to put in the gitlad link for the software code)


DCS and interlock for local support QC produce

The old setup for DCS and interlock are documented here: DCS Control/Monitoring for Inner Pixel Integration

For Big QC box in b33, the software for DCS and Interlock are documented here.

Hardware for DCS and interlock: documented in Fengrui's slides

Input sensor:

  1. RTD readout in the CO2 tower
  2. Humidity sensor: Vaisala DMT-143
  3. Module temperature 
    1. CAN Bus signals from MOPS chip
    2. NTC for interlock
  4. Module voltage from MOPS Chip
  5. door sensor for the QC box
  6. heart beat signal from pi (make sure pi is working properly)

Output:

  1. LV and HV for module
  2. Power relay
  3. flow control on CO2 tower

Detailed logic for DCS and Interlock are in the checklist
