| StateInput: DevVoid Output: State Device state |
This command gets the device state (stored in its device_state data member) and returns it to the caller. |
| StatusInput: DevVoid Output: ConstDevString Device status |
This command gets the device status (stored in its device_status data member) and returns it to the caller. |
| ConnectInput: DevVoid Output: DevVoid |
Connect to the OPC UA server. Reinitialise all event subscriptions. |
| DisconnectInput: DevVoid Output: DevVoid |
Disconnect from the OPC UA server. State will be UNKNOWN from now on. |

b'## TangoOpcUaObject class\n\nThis class aims to representing an OpcUa Object by defining properties.\nIt must be used with an OpcUaAccess device\n\n## Requirement\n\n- PyTango >= 8.1.6\n- freeopcua (an open-source (LGPL) OPC-UA stack and associated tools)\n- devicetest (for using tests)\n- sphinx (for building sphinx documentation)\n\nRun in terminal, to install requirements:\n\n\tpip install -r requirements.txt \n\n## Installation\n\nRun python setup.py install\n\nIf you want to build sphinx documentation,\nrun python setup.py build_sphinx\n\nIf you want to pass the tests, \nrun python setup.py test\n\n## Usage\n\nNow you can start your device server in any\nTerminal or console by calling it :\n\nTangoOpcUa instance_name\n\n### Device server properities\n\n- OpcUaServerAddress, e.g.: opc.tcp://192.168.64.12:4840\n- StateDe\xef\xac\x81nition , e.g.: MyDevice.Value!1:ON!2:OFF!3:ALARM!15:FAULT\n- OpcTags, e.g.: Resistance!Scalar!Double!READ_WRITE!DeviceName.Resistor1! DeviceName.Resistor1\n\n### Device server commands:\n\n- Connect\n- Disconnect\n\n'
