General Information 

This page collects various DCS control/monitoring information that include LV/HV control and monitoring, and monitoring of temperature, pressure, humidity etc. for both Lab setups and B33 integration. Interlocks have a dedicated page separately. 

Collection of specs for LV/HV PSU and associated infrastructure 

B84 EPP Lab Setup 

The B84 EPP lab DAQ readout and PSU communications are supported by the rack at the 'ATLAS corner', network switch and lab supplied on the test bench. The ITk DAQ Network page has detailed description of the readout network with the RDDEV111 host server and X display/terminal with fastx3.  Key equipment that require remote power controls can take regular 110V A/C power from ports served by the TripLite PDU in the rack.

 ISEG Control/Monitoring

Many PSUs and DCS monitoring components are from ISEG that are hosted in Wiener MPOD crates. An example control/monitoring of an ISEG HV module in the Wiener MPOD crate using SNMP in EPP lab from RDDEV111 through fastx3 on your laptop browser could look like this:

The Wiener MpodC controller itself is always on for basic communication to the crate when the crate is powered. To access the ISEG modules in the crate, the red on/off button on the MpodC controller module need to be ON to bring up power to the rest of the crate to make the ISEG modules visible. 

The initial setup of the control software from a session on RDDEV111:

Then each time to run control/monitoring session:

  • cd isegSnmpControl-SL71-x64-1.1.7.0/
  • bash ./start.sh
  • (First run may ask for module IP address in IP dialog).
  • Simply click Vset boxes to set desired values and right click Status box to get pull down menu to turn on/off etc. 

Raspberry Pi Based Control/Monitoring

Many small lab test setups and some part of the B33 integration setup are standardizing to the use of Raspberry Pi 4 to mediate the ethernet connection to the ITk DAQ network for communication and connecting to various types of sensors using dedicated shields. The control/monitoring program running on Raspberry Pi can also reach out through the ITk DAQ network to e.g. Agilent PSU through PROLOGIX ETH-GBIP adaptor for integrated control of module power.  

PI-SPI-8AI Analog Input 4-20mA Interface Raspbery Pi

PI-SPI-8AI Analog Input 4-20mA Interface Type Selection

Widgetloads Pi-SPi-8AI+ readout interface is widely in many test setups. It support 4 types of signals 4-20mA/5V VDC/10V VDC/Temp (NTC) which can be easily reconfigured to host a combination of these by solder fill of the appropriate pads at the back of the card.
