A python client for LADS OPC UA Server

Python Client for LADS OPC UA Server

Create a connection to the LADS Server using the server URL:

conn = Connection("your_server_url")

Start the connection to the server:

conn.connect()

Get the server object of the Connection class

serv = conn.server

Get the LADS Device list that is present in the LADS Server DeviceSet

devices = serv.devices

For a Device 'i' the list of Functional Units present inside that Device can be retrieved as

fu = devices[i].functional_units

The Function Set present inside a Functional Unit 'k' can be accessed as

fs = fu[k].function_set

The list of Functions present inside the Function Set can be retrieved as

funcs = fs.functions

Please be aware, that LADS specifies numerous function types, representing e.g. sensors, controllers, timers, lids/doors and so on. For further information refer to the specification and the workshop example.

Variables, methods and objects of a function can be easily accessed as properties, e.g. the Sensor Value of a Sensor Function 'j' can be accessed as

value = funcs[j].sensor_value.value

The connection to the server can be disconnected as

conn.disconnect()
