Device Node Tree¶

This chapter contains reference documentation for the settings and measurement data available on UHF Instruments. Whilst Functional Description LabOne User Interface describes many of these settings in terms of the features available in the LabOne User Interface, this chapter describes them on the device level and provides a hierarchically organized and comprehensive list of device functionality.

Since these settings and data streams may be written and read using the LabOne APIs (Application Programming Interfaces) this chapter is of particular interest to users who would like to perform measurements programmatically via LabVIEW, Python, MATLAB, .NET or C.

Please see:

Introduction for an introduction of how the instrument’s settings and measurement data are organized hierarchically in the Data Server’s so-called "Node Tree".
Reference Node Documentation for a reference list of the settings and measurement data available on UHF Instruments, organized by branch in the Node Tree.

Introduction¶

This chapter provides an overview of how an instrument’s configuration and output is organized by the Data Server.

All communication with an instrument occurs via the Data Server program the instrument is connected to (see LabOne Software Architecture for an overview of LabOne’s software components). Although the instrument’s settings are stored locally on the device, it is the Data Server’s task to ensure it maintains the values of the current settings and makes these settings (and any subscribed data) available to all its current clients. A client may be the LabOne User Interface or a user’s own program implemented using one of the LabOne Application Programming Interfaces, e.g., Python.

The instrument’s settings and data are organized by the Data Server in a file-system-like hierarchical structure called the node tree. When an instrument is connected to a Data Server, its device ID becomes a top-level branch in the Data Server’s node tree. The features of the instrument are organized as branches underneath the top-level device branch and the individual instrument settings are leaves of these branches.

For example, the auxiliary outputs of the instrument with device ID "dev2006" are located in the tree in the branch:

/dev1000/auxouts/

In turn, each individual auxiliary output channel has its own branch underneath the "AUXOUTS" branch.

/dev1000/auxouts/0/
/dev1000/auxouts/1/
/dev1000/auxouts/2/
/dev1000/auxouts/3/

Whilst the auxiliary outputs and other channels are labelled on the instrument’s panels and the User Interface using 1-based indexing, the Data Server’s node tree uses 0-based indexing. Individual settings (and data) of an auxiliary output are available as leaves underneath the corresponding channel’s branch:

/dev1000/auxouts/0/demodselect
/dev1000/auxouts/0/limitlower
/dev1000/auxouts/0/limitupper
/dev1000/auxouts/0/offset
/dev1000/auxouts/0/outputselect
/dev1000/auxouts/0/preoffset
/dev1000/auxouts/0/scale
/dev1000/auxouts/0/value

These are all individual node paths in the node tree; the lowest-level nodes which represent a single instrument setting or data stream. Whether the node is an instrument setting or data-stream and which type of data it contains or provides is well-defined and documented on a per-node basis in the Reference Node Documentation section in the relevant instrument-specific user manual. The different properties and types are explained in Node Properties and Data Types .

For instrument settings, a Data Server client modifies the node’s value by specifying the appropriate path and a value to the Data Server as a (path, value) pair. When an instrument’s setting is changed in the LabOne User Interface, the path and the value of the node that was changed are displayed in the Status Bar in the bottom of the Window. This is described in more detail in Exploring the Node Tree.

Module Parameters

LabOne Core Modules, such as the Sweeper, also use a similar tree-like structure to organize their parameters. Please note, however, that module nodes are not visible in the Data Server’s node tree; they are local to the instance of the module created in a LabOne client and are not synchronized between clients.

Node Properties and Data Types¶

A node may have one or more of the following properties:


Read	Data can be read from the node.
Write	Data can be written to the node.
Setting	The node corresponds to a writable instrument configuration. The data of these nodes are persisted in snapshots of the instrument and stored in the LabOne XML settings files.
Streaming	A node with the read attribute that provides instrument data, typically at a user-configured rate. The data is usually a more complex data type, for example demodulator data is returned as `ZIDemodSample`. A full list of streaming nodes is available in the Programming Manual in the Chapter Instrument Communication. Their availability depends on the device class (e.g. MF) and the option set installed on the device.

A node may contain data of the following types:


Integer	Integer data.
Double	Double precision floating point data.
String	A string array.
Integer (enumerated)	As for Integer, but the node only allows certain values.
Composite data type	For example, `ZIDemodSample`. These custom data types are structures whose fields contain the instrument output, a timestamp and other relevant instrument settings such as the demodulator oscillator frequency. Documentation of custom data types is available in

Exploring the Node Tree¶

In the LabOne User Interface

A convenient method to learn which node is responsible for a specific instrument setting is to check the Command Log history in the bottom of the LabOne User Interface. The command in the Status Bar gets updated every time a configuration change is made. Figure 1 shows how the equivalent MATLAB command is displayed after modifying the value of the auxiliary output 1’s offset. The format of the LabOne UI’s command history can be configured in the Config Tab (MATLAB, Python and .NET are available). The entire history generated in the current UI session can be viewed by clicking the "Show Log" button.

In a LabOne Programming Interface

A list of nodes (under a specific branch) can be requested from the Data Server in an API client using the listNodes command (MATLAB, Python, .NET) or ziAPIListNodes() function (C API). Please see each API’s command reference for more help using the listNodes command. To obtain a list of all the nodes that provide data from an instrument at a high rate, so-called streaming nodes, the streamingonly flag can be provided to listNodes. More information on data streaming and streaming nodes is available in the LabOne Programming Manual.

The detailed descriptions of nodes that is provided in Reference Node Documentation is accessible directly in the LabOne MATLAB or Python programming interfaces using the "help" command. The help command is daq.help(path) in Python and ziDAQ('help', path) in MATLAB. The command returns a description of the instrument node including access properties, data type, units and available options. The "help" command also handles wildcards to return a detailed description of all nodes matching the path. An example is provided below.

    daq = zhinst.core.ziDAQServer('localhost', 8004, 6)
    daq.help('/dev2006/auxouts/0/offset')
    # Out:
    # /dev1000/auxouts/0/offset#
    # Add the specified offset voltage to the signal after scaling. Auxiliary Output
    # Value = (Signal+Preoffset)*Scale + Offset
    # Properties: Read, Write, Setting
    # Type: Double
    # Unit: V

Data Server Nodes¶

The Data Server has nodes in the node tree available under the top-level /ZI/ branch. These nodes give information about the version and state of the Data Server the client is connected to. For example, the nodes:

/ZI/ABOUT/VERSION
/ZI/ABOUT/REVISION

are read-only nodes that contain information about the release version and revision of the Data Server. The nodes under the /ZI/DEVICES/ list which devices are connected, discoverable and visible to the Data Server.

The nodes:

/ZI/CONFIG/OPEN
/ZI/CONFIG/PORT

are settings nodes that can be used to configure which port the Data Server listens to for incoming client connections and whether it may accept connections from clients on hosts other than the localhost.

Nodes that are of particular use to programmers are:

/ZI/DEBUG/LOGPATH - the location of the Data Server’s log in the PC’s file system,
/ZI/DEBUG/LEVEL - the current log-level of the Data Server (configurable; has the Write attribute),
/ZI/DEBUG/LOG - the last Data Server log entries as a string array.

The Global nodes of the LabOne Data Server are listed in the Instrument Communication chapter of the LabOne Programming Manual
