Why generic devices ? Ø To keep all the intelligence in the device. ü To make the GUI ready to use quickly. ü To make the GUI easy to maintain. ü To limit the number of iterations in the GUI development. Ø To provide a modular solution. ü To carry out a device server without programming. ü To solve a recurring problem. ü To make a device easy to maintain. ü To limit the number of iterations in the device development. Ø To isolate a complex interface into simple entities ü To employ all the ready to use tools dedicated to theses entities. • polling, archiving… September 2006 3

Averager (java) Calculation of the average and the standard deviation of any numerical tango scalar attribute : Ø To follow a slow data variation. Ø To archive less values. Ø To smooth a curve. Ø To eliminate the noise and to apply a filtering. September 2006 4

Tango. Parser (java) Calculation of tango attributes the values of which are mathematical expressions of other tango attributes. The expression can be defined at runtime in a mathematical syntax. Ø To convert a data. Ø To average several attributes. Ø In short to make any type of calculations September 2006 5

Boolean. Attribute. Extractor (java) Extraction of several Boolean values from any scalar attribute representing a field of bytes. Ø To poll the Boolean attribute. Ø To realized a simple GUI with an existing ATK widget. Ø To archive a simple information. September 2006 6

Enumerated. Attribute (java) To predefine an enumerated list of values for a tango scalar attribute. Boolean attributes are dynamically created. ØTo poll the Boolean attribute. ØTo move the intelligence of the ATK widget in the device. Ø To carry out a simple GUI with a simple ATK widget. Ø To archive a simple information. Ø To give an explicit name to an attribute value. September 2006 7

Enumerated. Command (java) To predefine an enumerated list of values for a tango scalar command. Void command are dynamically created. Ø To poll a void command. Ø To move the intelligence of the ATK widget in the device. Ø To realized a simple GUI with a simple ATK widget. Ø To give explicit names to a command value. September 2006 8

Slicer (c++) To extract a simple scalar data from a spectrum or a spectrum from an image tango attribute. Ø To handle multidimensional data (2 D, 3 D) projection. Ø To archive this data. Ø To represent this data with a existing ATK widget. September 2006 9

Data. Fitter (C++) To apply a Gaussian or Lorentzian function, in order to get different pieces of information like the width of the peak, the half height intensity…. September 2006 10

Attribute. Composer (java) To build a spectrum attribute starting from simple scalar tango attributes. Ø To make a soft synchronization of the data. Ø To archive a set of data. Ø To display easily all the data in a chart. Ø To deduce a general state according to the attribute quality. Ø To represent the general state with a simple ATK widget. Ø To write the same value on several attribute. Ø To give the logical result (OR, XOR, AND gate), on a list of Boolean attributes. September 2006 11

State. Composer (java) To deduce general state according to a list of devices. Ø To archive the state information. Ø To represent the general state with a simple ATK widget. Ø To execute a grouped command on several device. September 2006 12

Facade. Device (java) Construction of a new device starting from attributes, commands and state of other devices. Ø To hide a part of a device. Ø To install quickly a simulated device in order to test a GUI. Ø To gather information in only one device. Ø To create a basic device server without developing. Ø To created an intermediary device when the tango interface of a device changes. September 2006 13

Beam. Image. Analyzer (C++) Computation of different metrics on a beam image: Ø Beam box (bounding rectangle of the beam) Ø Approximation of the beam contour by an ellipse Ø Computation of moments from order 0 to 3 Ø Profiles against both axis and Gaussian fit of these profiles Ø 2 D Gaussian fit of the image September 2006 14

Example September 2006 15

Attribute. Sequence. Writer (C++) Written Value To write a sequence. Read (once Valueor repeatedly) of values on a writable attribute of another device. Ë2 ËDelta Ø The user have to configure : ü the sequence of values to write. ü the sequence of waiting times. Ë1 ËDelta Ø Then we just have to start the generation of values. Ø The device can wait for the read part has reached the write part. - Mainly used for cycling the magnets power supplies. Ë0. 5 s September 2006 Ë1 s Ëtime 16

Results Ø New device servers : ü Supervision of a group of devices (Composers) q Group of power supplies, ion pumps, vacuum valve… ü Installation of a simulated tango environment (Facade. Device) q Adapting Tango. Test to any required Device. Server interface ü Devices providing a near hardware solution q Motorized Insertion/Extraction in the beam. q Uncoupling motorized device like a mirror. q Extraction of a device default information. Ø GUI development. ü ATKPanel answers quickly to a supervision problem. ü Specific GUIs are easily developed. September 2006 17

Java API improvement needs ØBoolean attributes ØDeletion of dynamics attributes and commands ØGroup and asynchronies commands ØMemorized attributes. September 2006 18
