CheckLongRunningCommandStatus(argin: str) str

Check the status of a long running command by ID.

Parameters:

argin – the command id

Returns:

command status

DebugDevice() int

Enable remote debugging of this device.

To modify behaviour for this command, modify the do() method of the command class: DebugDeviceCommand.

Returns:

the port the debugger is listening on

DeviceID

TANGO property

ExecutePendingOperations() None

Execute any Tango operations that have been pushed on the queue.

The poll time is initially 5ms, to circumvent the problem of device initialisation, but is reset to 100ms after the first pass.

GetVersionInfo() list[str]

Return the version information of the device.

To modify behaviour for this command, modify the do() method of the command class.

Returns:

The result code and the command unique ID

GroupDefinitions

Device property.

Each string in the list is a JSON serialised dict defining the group_name, devices and subgroups in the group. A Tango Group object is created for each item in the list, according to the hierarchy defined. This provides easy access to the managed devices in bulk, or individually.

The general format of the list is as follows, with optional devices and subgroups keys:

[ {"group_name": "<name>",
   "devices": ["<dev name>", ...]},
  {"group_name": "<name>",
   "devices": ["<dev name>", "<dev name>", ...],
   "subgroups" : [{<nested group>},
                    {<nested group>}, ...]},
  ...
  ]

For example, a hierarchy of racks, servers and switches:

[ {"group_name": "servers",
   "devices": ["elt/server/1", "elt/server/2",
                 "elt/server/3", "elt/server/4"]},
  {"group_name": "switches",
   "devices": ["elt/switch/A", "elt/switch/B"]},
  {"group_name": "pdus",
   "devices": ["elt/pdu/rackA", "elt/pdu/rackB"]},
  {"group_name": "racks",
   "subgroups": [
        {"group_name": "rackA",
         "devices": ["elt/server/1", "elt/server/2",
                       "elt/switch/A", "elt/pdu/rackA"]},
        {"group_name": "rackB",
         "devices": ["elt/server/3", "elt/server/4",
                       "elt/switch/B", "elt/pdu/rackB"],
         "subgroups": []}
   ]} ]
