Main tasks of the MPD slowcontrol

What is slowcontrol, hardware and software-wise

1. Monitoring of the experimental hardware 2. Control of the SlowControl equipment (LV, HV, gas flow etc.)3. Archiving SlowControl data4. Alarm system

Not a slowcontrol:- Main data stream (data taking)- Event builder (reconstruction)/event display- Data quality- Run control

Tango vs EPICS vs commercial SCADA

- entry level complexity- existence of wide active collaboration- open source / price- support price…

Tango Controls system as a backbone of the MPD slowcontrol

- client-server architecture- tango database and data databases: MySQL

• Historical DataBase - HDB - HdbArchiver, ArchivingManager, HdbExtractor, HdbArchivingWatcher

• Temporary DataBase - TDB - TdbArchiver, ArchivingManager, TdbExtractor, TdbArchivingWatcher

• Snapshots – SNAP

mambo - archiving tasks GUI

- code generator - application Toolkits (Java, C++ and Python) - commercial bindings (Labview, Matlab …) - central services (Archive, snapshots, logging, alarms …

- slowcontrol typically most heterogeneous subsystem in any experiment-> one of the major goals is to present SC data in common format for further processing

- MPD slowcontrol mainly uses centralized MPD computing resources - virtual machines controlled by Proxmox Virtual Environment

- slowcontrol typically being developed later than major parts of all other subdetectors-> requires easy scalability

- slowcontrol @ BM@N experiment at Nuclotron as a test-bench for MPD SC

Conclusion

- Created base structure of SlowControl for MPD including databases, archiving system, alarms system, etc.- Developed software for some hardware used in MPD subdetectors slowcontrol: - MKS647 – gas flows monitoring and control - ICPCON7017-10 ADC – monitoring of Low Voltage, leakage currents, etc - temperature monitoring - LED calibrators control and monitoring - part of the HV control - etc.- Slowcontrol system was testes during BM@N run at Nuclotron.

Problems:

- manpower (mainly for devices programming) - convincing subdetector groups to pay more attention to their slowcontrol tasks in

frame of the unified MPD slowcontrol.
