About

The nisystemlink-clients package contains an API (Application Programming Interface) for SystemLink <https://ni.com/systemlink>_ that uses HTTP to interact with a SystemLink Server. The package is implemented in Python. NI created and supports this package.

Requirements

nisystemlink-clients has the following requirements:

• Access to a SystemLink Server or SystemLink Enterprise installation
• CPython 3.11+ (tested on 3.11-3.15)

DataFrame compatibility

Python 3.11-3.14 uses pandas 2; Python 3.15+ uses pandas 3. DataFrame conversion helpers follow the installed pandas version's native behavior. Moving to Python 3.15 can therefore change inferred string dtypes, timestamp units (for example, microseconds instead of nanoseconds), and missing-value representations. Review downstream dtype assumptions and serialization when upgrading.

.. _installation_section:

Installation

To install nisystemlink-clients, use one of the following methods:

1. pip <https://pypi.python.org/pypi/pip>_::

   $ python -m pip install nisystemlink-clients

2. easy_install from setuptools <https://pypi.python.org/pypi/setuptools>_::

   $ python -m easy_install nisystemlink-clients

Optional Arrow (pyarrow) Support

The base install does not pull in pyarrow. Arrow RecordBatch ingestion via DataFrameClient.append_table_data is available starting in nisystemlink-clients version 2.19.0. Install that version (or newer) with the optional extra:

$ python -m pip install "nisystemlink-clients[pyarrow]>=2.19.0"

If you already have an older version installed, upgrade with:

$ python -m pip install --upgrade "nisystemlink-clients[pyarrow]>=2.19.0"

Without the extra (or when using a package version earlier than 2.19.0), Arrow-specific code paths will raise a RuntimeError when attempting to append pyarrow.RecordBatch instances.
