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 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)
