Detector Control System for ELITPC detector using OPC UA protocol. Provides server, operational gui client and database client. Server is compatible with other OPC UA clients such as UaExpert by Unified Automation.

Getting Started

Prerequisites

C++11 compiler and cmake>3.1

This project requires open62541 (open source C implementation of OPC UA) version 1.1 or newer build with enabled methodcalls, subscriptions (enabled by default), events, historizing, multithread-safety and full namespace 0. You may change -DCMAKE_INSTALL_PREFIX for custom installation (in that case you should also edit env.sh with the same path):

git clone https://github.com/open62541/open62541
cd open62541
git checkout v1.1
git submodule update --init --recursive
mkdir build && cd build
cmake -DUA_NAMESPACE_ZERO=FULL  -DBUILD_SHARED_LIBS=ON -DUA_ENABLE_HISTORIZING=ON -DUA_ENABLE_SUBSCRIPTIONS_EVENTS=ON -DUA_MULTITHREADING=150 -DCMAKE_BUILD_TYPE=RelWithDebInfo -DCMAKE_INSTALL_PREFIX=/opt/soft/open62541 ..
make
sudo make install

Furthermore the GUI clients requires Qt5 :

sudo apt-get install qt5-default

Extras

The dcs may store the measurments in the InfluxDB 1.x database. InfluxDb 1.8.3 installation:

wget https://dl.influxdata.com/influxdb/releases/influxdb_1.8.3_amd64.deb
sudo dpkg -i influxdb_1.8.3_amd64.deb

The extra Python tools (for dumping database) to text file require influxDB API and pandas :

pip3 install pandas influxdb

Building

git clone --recursive ssh://[email protected]:8822/mfila/dcs.git
cd dcs
. env.sh
mkdir build && cd build
cmake ..
make
make install

CMake flags -DBUILD_GUI -DBUILD_SERVER -DBUILD_CHECKS can be switched to OFF to disable building some parts of the project. cmake -DCMAKE_INSTALL_PREFIX=your_path .. can be used to specify custom installation path.

Upon successful build the resulting executables dscServer, dcsGui and `dcsChecks will be available:

• dcsServer - provides OPC server and device controllers. Should be run on a computer with access to devices.
• dcsGui - GUI client. Provides graphic interface for operator user of services exposed by server such as monitoring and manipulating devices.
• dcsChecks - checks status of services running in ELITPC dcs stack: dcsServer, InfluxDb, Grafana.

Usage

• to run server:

  ./dcsServer (path_to_config_file)
  

• to run gui client:

  ./dcsGUI (path_to_config_file)
  

• to run service checks :

  ./dcsChecks (path_to_config_file)
  

At startup server and clients look for configuration file with list of devices used in experimental setup and address of a server. So far known devices are:

• HMP2020 - 2 channel lv psu
• HMP4040 - 4 channel lv psu
• DT1415ET - 8 channel hv psu
• DT1740ET - 4 channel hv psu
• N1471 - 4 channel NIM hv psu
• TPG362 - vacuum gauge
• MKS910 - vacuum gauge
• MKS946 - vacuum gauge
• PiWeather - custom Raspberry Pi powered weather station

A path to config file should be given in first argument for server or client application. Otherwise an enviromental variable will be looked for.

Enviromental variables

During initialisation dcsServer looks for enviromental variables.

• ${DCS_CONFIG_FILE} - path to server configuration (currently json) file. Default value is ${HOME}/.dcs/dcs.json.First argument given to dcsServer has higher priority than this enviromental variable
• ${DCS_PROFILE_DIR} - path to directory with device profiles. Default value is ${HOME}/.dcs/. Config field profileDir has higher priority than this enviromental variable

Adding new devices (old)

The project is split into two catalogs COREdcs with framework and ELITPCdcs implementing specific devices. Ideally you shouldn't have to edit anything in COREdcs.

Server

• bin/main.cpp create specific device controller if found in config file
• ${device} hardware communication with device
• ${device}controller device specific methods and update routines for variables of OPC object

GUI client

• mainwindow.cpp create specific device controller if found in config file
• ${device}controller slots for calling device specific methods
• ${device}widget device specific gui

Roadmap

• new devices (MKS 946)
• interlock support
• server events
• historizing
• refactorized server
• server device register
• server device profiles/presets
• refactorized client
• client events
