Plugin: Q.station EPICS server (GInsEpicsServerPlugin)

How to setup a Q.station server plugin to stream data to EPICS software tools

Background

EPICS is a set of Open Source software tools, libraries and applications developed collaboratively and used worldwide to create distributed soft real-time control systems for scientific instruments such as particle accelerators, telescopes and other large scientific experiments.

A Q.station plugin (GInsEpicsServerPlugin) is available to create an Epics server within the controller to stream the data from the data acquisition system to the Epics software tools.

Install plugin

  1. Reach out to a Gantner representative for the download link for the EPICS Q.station plugin version that matches the Q.station firmware you currently have installed.
  2. Use the Firmware Manager tool or GI.bench to install the plugin: https://knowledge.gantner-instruments.com/how-to-install-a-pluginhttps://knowledge.gantner-instruments.com/how-to-install-a-plugin

Read variables

By default all variables from process image should be available from EPICS world via CA (channel access). There is a prefix Loc.PI.<VARIABLE NAME> to identify our variables in EPICS.

For Windows, this software is an example of one that can be used.

In this example test setup with a Q.station XT some setpoint virtual variables were created.
