The Common Device Interface (CDI) [1] is a popular device layer in TINE control systems [2]. Indeed, a de-facto device server (more specifically a 'property server') can be instantiated merely by supplying a hardware address database, somewhat reminiscent of an epics IOC. It has in fact become quite popular among uses to do precisely this, although the original design intent anticipated embedding CDI as a hardware layer within a dedicated device server. When control system client applications and central services communicate directly to a CDI server, this places the burden of providing useable, viewable data (and in an efficient manner) squarely on CDI and its address database. In its initial release variant, any modifications to this hardware database needed to be made on the file system used by the CDI device server. In this report we shall describe some of the many new features of CDI release 2.0, which have drawn on the user/developer experience over the past eight years.

The PyPLC [1] Tango Device Server provides a developer-friendly dynamic interface to any Modbus-based control device. Raw data structures from PLC are obtained efficiently and converted into highly customized attributes using the python programing language. The device server allows to add or modify attributes dynamically using single-line python statements. The compact python dialect used is enhanced with Modbus commands and methods to prototype, simulate and implement complex behaviors. As a generic device, PyPLC has been versatile enough to interact with PLC systems used in ALBA [2] Accelerators as well as to our Beamlines SCADA (Sardana [3]). This article describes the mechanisms used to enable this versatility and how the dynamic attribute syntax allowed to speed up the transition from PLC to user interfaces.

| FPO029 | Redesign of Alarm Monitoring System Application "BeamlineAlarminfoClient" at DESY | GUI, controls, monitoring, software | 219 |
|
|||
| The alarm monitoring system “BeamlineAlarminfoClient” is a very useful technical-service application at DESY, as it visually renders the locations of important alarms in some sections (e.g. fire or other emergencies). The aim of redesigning this application is to improve the software architecture and allow the easy integration of new observable areas including a new user interface design. This redesign also requires changes on server-side, where alarms are handled and the necessary alarm information is prepared for display. Currently, the client manages alarm data from 17 different servers. This number will increase dramatically in 2014 when new beam lines come into play. Thus creating templates to simplify the addition of new sections makes sense both for the server and client. The client and server are based on the Tine control system and make use of the Tine-Studio utilities, the Alarm Viewer and the Archive Viewer. This paper presents how the redesign is arranged in close collaboration with the customers. | |||

| FCO206 | PANIC, a Suite for Visualization, Logging and Notification of Incidents | TANGO, controls, database, PLC | 246 |
|

PANIC is a suite of python applications focused on visualization, logging and notification of events occurring in ALBA [1] Synchrotron Control System. Build on top of the PyAlarm Tango [2] Device Server it provides an API and a set of graphic tools to visualize the status of the declared alarms, create new alarm processes and enable notification services like SMS, email, data recording, sound or execution of Tango commands. The user interface provides visual debugging of complex alarm behaviors, that can be declared using single-line python expressions. This article describes the architecture of the PANIC suite, the alarm declaration syntax and the integration of alarm widgets in Taurus [3] user interfaces.
