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

Control System Interfaces
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

Control System Interfaces
Special Features (2): Addressing with System Mask
All sections belonging to SASE2 e- beam lines


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
