This is a shared repository for common classes required for Telescope Monitoring and Control(TMC) work package of SKA Telescope software.
The ska-tmc-common repository contains implementation of Tango abstraction layer. It provides the abstraction in form of following classes: TangoClient: Class that provides abstraction for Tango client APIs TangoGroupClient: Class that provides abstraction for Tango group APIs TangoServerHelper: Class that provides abstraction for Tango device server APIs TangoHelperDevices: Class that provides abstraction for Various TMC Tango devices for Testing and debugging
The basic requirements are:
- Python 3.5
- Pip
The requirements for installation of the lmc bas classes are:
- enum34
- argparse
- future
The requirements for testing are:
- coverage
- pytest
- pytest-cov
- pytest-xdist
- mock
pip install --index-url https://artefact.skao.int/repository/pypi-internal/simple' ska-tmc-common
- Clone the repository on local machine.
- Navigate to the root directory of the repository from terminal
- Run
python3 -m pip install . --extra-index-url https://artefact.skao.int/repository/pypi-internal/simple
The TMC common classes are installed as a Python package in the system. The intended usage of the base classes is to import the class according to the requirement. The class needs to be imported in the module.
To use the TangoClient, the usage is as follows:
from ska.tmc.common import TangoClient
.
.
.
my_client = TangoClient("device-FQDN")
my_client.send_command("DeviceCommand", param)To use the TangoServerHelper class, the usage is as follows:
from ska.tmc.common import TangoServerHelper
.
.
.
my_server = TangoServerHelper.get_instance()
my_server.set_tango_class(device)
my_server.get_state()
my_server.read_attr("MYATTR")
