PV status low, high, lolo, hihi always set to 0

[GoogleCodeExporter]

I am not able to set some value to the low, high, lolo, hihi status variables. 
In the example alarm_severity.py in the pcaspy-0.4.1/example directory the 
variables are set to not equal zero:

$ python alarm_severity.py

in another console cainfo does not show me any alarm values:

$ cainfo MTEST:RAND

MTEST:RAND
    State:            connected
    Host:             10.0.2.15:5064
    Access:           read, write
    Native data type: DBF_DOUBLE
    Request type:     DBR_DOUBLE
    Element count:    1

I also tried with pyepics on the ipython console:

In [1]: import epics
In [2]: pv=epics.PV('MTEST:RAND')
In [3]: print pv.info                                            
== MTEST:RAND  (native_double) ==
   value      = 0
   char_value = '0'
   count      = 1
   nelm       = 1
   type       = double
   units      = 
   precision  = 3
   host       = 10.0.2.15:5064
   access     = read/write
   status     = 17
   severity   = 3
   timestamp  = 1412767230.217 (2014-10-08 04:20:30.21738)
   upper_ctrl_limit    = 0.0
   lower_ctrl_limit    = 0.0
   upper_disp_limit    = 0.0
   lower_disp_limit    = 0.0
   upper_alarm_limit   = 0.0
   lower_alarm_limit   = 0.0
   upper_warning_limit = 0.0
   lower_warning_limit = 0.0
   PV is internally monitored, with 0 user-defined callbacks:
