Values to be controlled – monitored

mezz card

CSM card

Monitor of:• Mezz Temperature value• Mezz V analog value• Mezz V digital value• CSM all provided values (e.g. CSM temperature, 2.5 V ref. value)

What this system has to offer as a Detector Control System1. hardware to be controlled and monitored2. interaction with other systems (LV)

Overview of ELTX DCS Architecture

The main asset of the project is the gathering of information spread in several DCS pcs and DBs

FSM is the heart of DCS , it organizes the devices / logical nodes in a parent –childrenstructure.

ALARM Mechanism

1. node state 2. csm state 3. csm 2.5V ref V

4. Mezz Temperature 5. Mezz Analog V6. Mezzanine Digital V7. CSM temperature8. CSM 2.5V ref V

The alarm screen is the first user inteactive mechanism

Interactive features

1.Check the OPC server from PS machines.In case of stop of opc server a mail and a SMS message is sent to:- the ELTX expert (Charilaos Tsarouchas)- The PS expert (Eleni Mountricha)

2.Debug panel of chambers in state UNKNOWN

The ELTX 4 piece puzzle

Each piece can work alone but in order to have a real online status of out detectorall pieces should run in parallel and communicate each other.
