CSS Core Applications

• Alarms and the Alarm System• The EPICS IOC application development

process• Applications in the control room• Diagnostic Tools



Alarms and the Alarm System

• The first CSS based Application which went fully into operation

• Requirements driven by ‘on call’ operators

Alarm Displays

• Alarm Table– AlarmTables may be connected to one or more JMS Topics

(dynamically) – Alarm Tables may be (alternatively)updated by channel access monitors

– using a XML config file for channel list (NEW)*• Log Table • Log Tables may be connected to one or more JMS Topics

(dynamically) • Alarm-Tree

– Get the configuration from LDAP (default)– Reading configuration from XML File (NEW)*

(* Local Alarm Displays can run independently from LDAP and JMS)



Alarm Table



Looking back into the Archive (24h) from Oracle



Log Messages (System, Put, SNL)



Alarm System- Alarm Tree view

• Shows the current status of the alarm state from the IOC• Delete and create records and subcomponents by context menu• Configuration-Changes are stored in the LDAP server (or in XML file)• Alarm status is propagated to root component• Property view to display and edit tree items



The EPICS IOC application development process

• Developers– EPICS IOC core software (e.g. drivers)– Device configuration– EPICS database configuration

• Working model– Device configuration by the hardware engineer

• Add/ Change devices in RDB based device configuration tool– EPICS control database by the process engineer using CSS-

DCT independent from hardware engineerDatabase size: 2500/ 1500 records

Change in Prototype inherited to 150 instances

Datbase Creation Tool

A Tool to create hierarchical EPICS Databases• Lessons learned from previous developments• Integrated in CSS as a plugin

– Use csv to manage version control– Basic Graphical Representation

• Integrated with the I/O configuration Tool(share unique IO_NAMEs to configure the address space)

• Using Extension Point to create:– EPICS database file– Entries in RDB (Oracle)– XML file to create hierarchical Alarm-Tree (next release)



DCT – Database Creation Tool

SNL Editor



Applications in the Control Room

• CSS including DCT, device config, SNL editor– Ideal for commissioning – the ‘all in one’ toolkit

• Synoptic Display Studio– Several thousand (dm2k) ald files got converted

• Alarm Displays• Log Table

– Specially the possibility to list log messages from SNL programs

• dataBrowser• Name Space Browser (LDAP)• Screendump



SDS Displays – Faceplates - run ‘as shell’



Name Server Support

• Using the output of dbl > /fileServer/iocName• ldapUpdater

– CSS headless application (product)– checking /fileServer/* for new/updated files– Updating entries in the LDAP server

• NameSpaceBrowser– CSS plug-in– Read entries from LDAP server– Browse LDAP tree– Search for records in LDAP– Drag and Drop support to other CSS plugins



Screenshot

Activation:•Activate from any view by <CTRL+Alt+S> (important for detached views)•Screenshot Menu in SDS Graphics•Icon in CSS Menu



Screenshot Actions

• Copy view to buffer• Copy from buffer to view• Send image via e-Mail• Send image to e-Logbook• Once activated:

– select view as image– select window as image– select screen as image
