Getting started with Dahu

Register Dahu with an existing Tango database

Assuming you have a tango database running on port 10000, you can register a server instance (called “dahu” in this example)

TANGO_HOST=localhost:10000 dahu-register --instance dahu

Note: you can register more than one Dahu tango device with the same server. Type dahu-register –help for more information.

To start a Dahu server that has been registered with a tango database running on port 10000:

TANGO_HOST=localhost:10000 dahu-server dahu

To use a tango device managed by this server:

from PyTango import DeviceProxy
p = DeviceProxy("tango://localhost:10000/id00/dahu/1")

To start a Dahu server that has not been registered with a tango database:

dahu-server dahu -ORBendPoint giop:tcp::10001 -nodb -dlist id00/dahu/1 -v4

To use a tango device managed by this server:

from PyTango import DeviceProxy
proxy = DeviceProxy("tango://localhost:10001/id00/dahu/1#dbase=no")
