Example: TINE - DOOCS Interface Java e.g. jddd TINE Server Ti D DAQ Get(adr, dataIn, dataOut) Standard Application Programming Interface API D Ti k E Ta Native libraries of the control systems jdoocs Equipment Name Server ENS Adr   protocol, server adr Data transformation to uniform format XFEL Collaboration Meeting April 2013 Kay Rehlich, DESY

TINE - DOOCS Interface: Data Types In total ~ 90 data types 75 % can be translated TINE  DOOCS 25 % are special types e.g. for archiving A data type can hold a single bit … up to 32MB (image) Data types can be quite complex: Archive types, images, … The API provides many functions like: get_float_2D ( row, col )  has to be implemented for all types XFEL Collaboration Meeting April 2013 Kay Rehlich, DESY

Special Features (1): Addressing with Wild-cards BPM simulation server ADR = XFEL.DIAG/BPM/*/Y All controls interfaces should support this, If not it has to be simulated XFEL Collaboration Meeting April 2013 Kay Rehlich, DESY

Special Features (2): Addressing with System Mask All e- beam lines All sections belonging to SASE2 e- beam lines System Mask: Inj 2 SASE xx XFEL Collaboration Meeting April 2013 Kay Rehlich, DESY

DOOCS: facility/device/location/property Address Conventions DOOCS: facility/device/location/property TINE: context/server/device/property TANGO: domain/family/member/property EPICS: flat, no standard definition Requires entries in the DOOCS name server karabo: device(=facility/device/location)/property DOOCS addresses require static entry in karabo-DB XFEL Collaboration Meeting April 2013 Kay Rehlich, DESY

Undulator Interface per Section Control System Interface Dynamic configuration of locations and properties DOOCS Undulator Server D Request Port: List of ports r 1 n Publisher Port: Sends changed data 0MQ Gateway 1 n UND 1 UND n . . .
