Server ------ Configuration ............. The configuration code consists of a :ref:`Node() ` section, and one :ref:`Mod() ` section per SECoP module. The **Node** section contains a globally unique ID of the SEC node, a description of the SEC node and the server interface uri. Example: .. code:: python Node('globally.valid.identifier', 'a description of the SEC node', interface = 'tcp://5000') For the interface scheme currently only tcp is supported. When the TCP port is given as an argument of the server start script, **interface** is not needed or ignored. The main information is the port number, in this example 5000. All other :ref:`Mod() ` sections define the SECoP modules. Mandatory fields are **name**, **cls** and **description**. **cls** is a path to the Python class from where the module is instantiated, separated with dots. In the following example the class **HeLevel** used by the **helevel** module can be found in the PSI facility subdirectory frappy_psi in the python module file ccu4.py: .. code:: python Mod('helevel', 'frappy_psi.ccu4.HeLevel', 'this is the He level sensor of the main reservoir', empty_length = Param(380, export=False), full = Param(0, export=False)) It is highly recommended to use all lower case for the module name, as SECoP names have to be unique despite of casing. In addition, parameters, properties and parameter properties might be initialized in this section. In the above example **empty_length** and **full_length** are parameters, the resistivity of the He Level sensor at the end of the ranges. In addition, we alter the default property **export** of theses parameters, as we do not want to expose these parameters to the SECoP interface. Starting ........ The Frappy server can be started via the **bin/frappy-server** script. .. parsed-literal:: usage: bin/frappy-server [-h] [-v | -q] [-d] [-t] [-p port] [-c cfgfiles] name Manage a Frappy server positional arguments: name name of the instance. Uses /name_cfg.py for configuration optional arguments: -c, --cfgfiles config files to be used. Comma separated list. defaults to when omitted -p, --port server port (default: take from cfg file) -h, --help show this help message and exit -v, --verbose output lots of diagnostic information -q, --quiet suppress non-error messages -d, --daemonize run as daemon -t, --test check cfg files only
