class OnCommand(target, op_state_model, logger=None)[source]

Bases: OnCommand

The command class for the On command.

Returns:: A Tuple containing a return code and a string message indicating status. The message is for information purpose only.

class OffCommand(target, op_state_model, logger=None)[source]

Bases: OffCommand

The command class for the Off command.

Turn off both outlets that provide power to the LRU. Device is put in the OFF state if both outlets were successfully turned off.

do() → Tuple[ResultCode, str][source]

Implement Off command functionality.

Returns:: A Tuple containing a return code and a string message indicating status. The message is for information purpose only.

DebugDevice()

Enable remote debugging of this device.

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

GetVersionInfo()

Return the version information of the device.

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

Returns:: Version details of the device.

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": []}
   ]} ]
