Synoptic = drag-and-dropGraphical User Interface (GUI) builder

and runtime environment.

4Wednesday, March 14, 2012

The “old” GUI environment (ACNET Console) is inadequate

5Wednesday, March 14, 2012

The “new” GUI environment (Java et al.) is too complex

6Wednesday, March 14, 2012

Synoptic = environment forapplications created by users.

Not specific to any particularsystem or experiment.

The LCD approach:set of functions that suits the majority

of users and works everywhere.

Component Types

1. Active components.

• Visible: gauges, plots, state indicators.

• Invisible: data sources & converters.

2. Links between active components.

3. Passive components: static images.

4. Embedded displays.

Data Sources

Convert structured data into primitive data types.

35Wednesday, March 14, 2012

• Array Splitter.

• Bitmask.

• Comparator.

• Delay Line.

• Discriminator.

• Expression.

• Integrator.

• Multiplexer.

• Splitter.

• Subtractor.

Connecting Components

To start a link, click or “c”.

37Wednesday, March 14, 2012

Who Produced Data?

• Data Tag is generated by data sources and converters and distributed through links along with data.

• Can be used in formatted text output produced by some gauges.

• For simple data sources, the data tag is set to the device name by default.

Parametrized Displays

49Wednesday, March 14, 2012

Parameters are passed to the display during startup, e.g.:

/Demo/Meteo(DEV=g:outtmp,BG=gold)

Each parameter replaces one or more component properties.

50Wednesday, March 14, 2012

Two Methods

1. Declaring global properties:One or more properties are mapped to a name available externally.

2. Text substitution:Part of a text property value is substituted with a string provided externally.

Suggestions on new features and discussions of use cases are always

welcome!

58Wednesday, March 14, 2012

Synoptic isn’t good for...

• One-shot data acquisition.

• Components that require complex configuration.

• Changing DAQ attributes on the fly.

• User input other than device settings.

59Wednesday, March 14, 2012

Portability

• Open-source version is publicly available (BSD license).

• You’ll have to set up the entire infrastructure.

• Using multiple control systems in one installation won’t work.

60Wednesday, March 14, 2012

Synoptic Instance #1:

Fermilab site. Main control system.

Synoptic Instance #2 (in progress):

Ash River site. Acnet-in-a-Rack.

61Wednesday, March 14, 2012

Upcoming Features

• Built-in parameter lookup table.

• ACL scripts.

• 3D plots.

• Mobile version, HTML5 support.
