Here is an example of how an environment variable can be accessed via a taurus device:

p09/door/haso107d1.01 [3]: import taurus

p09/door/haso107d1.01 [4]: door = taurus.Device('p09/door/haso107d1.01')

p09/door/haso107d1.01 [5]: door.macro_server.setEnvironment( "var", "value")

p09/door/haso107d1.01 [6]: door.macro_server.getEnvironment( "var")
               Result [6]: 'value'

p09/door/haso107d1.01 [7]: door.macro_server.removeEnvironment( "var")
