The Goal of Controls Configuration Data Management

The Goal of Controls Configuration Data Management

The Goal of Controls Configuration Data Management Given a signal provide as much related information as possible. For example: -Device Location (rack, room) -Device hardware configuration -Device software configuration -Device Serial number -PV archiving configuration -PV alarm configuration -Connection and cables details -Calibration records -Drawings -History -Access rights

Control system configuration Apps The BIG Configuration Database

Control system configuration Apps IOC Factory Configuration and deployment of EPICS IOCs Cable Database : Registry of cables types and individual cables Controls Configuration Database (CCDB): Static, physical attributes of the installation slots devices types and devices Naming System : Registry of naming structure and device names Device names Device Properties Device names

Control system configuration Apps IOC Factory Configuration and deployment of EPICS IOCs Cable Database : Registry of cables types and individual cables Controls Configuration Database (CCDB): Static, physical attributes of the installation slots devices types and devices Naming System : Registry of naming structure and device names Device names Device Properties Device names -Mandatory registration for signal generating devices. -Can be used for other devices -Used currently for Accelerator and ICS cables. -Available to other systems -Data export features -Specific to ICS -Some features will be available to remote sites -Mandatory for ICS owned equipment -Will be available for others -Data export features

How to explain EPICS to your boss: Network protocol: Channel Access EPICS is a network-based “client/server” model (hence the EPICS logo) Signal: Process Variable (PV) IOC (Input Output Controller) A list of Process Variables LINAC:BPM4:xPosition mm Channel Access Clients (CA Client) NAME: SPK-020LWU:PWRC-PS-010.Curr VALUE: 18 A Channel Access Servers (CA Server)

12 Channel Access in One Slide CA Server CA Client Process Variables: Channel Access Server SPK-020LWU:PWRC-PS-010:Curr SPK-020LWU:PWRC-PS-010:x SPK-020LWU:PWRC-PS-010:y Channel Access Client Who has a PV named “SPK-020LWU:PWRC-PS-010:Curr”? I do. What is its value? 18.5 AMPS Change its value to 30.5 “connection request” or “search request” OK, it is now is too high. It is now set to the maximum value of You are not authorized to change this value Notify me when the value changes It is now 20.5 AMPS It is now 10.5 AMPS It is now AMPS “put” or “caPut” “get” or “caGet” “set a monitor” “post an event” or “post a monitor” “put complete” or
