Experimental Physics and
Industrial Control System

Dear all,

I just found this problem on two different Debian machines (testing,
unstable), x86_64. On Scientific Linux (6.5), also x86_64, the problem
does not show up. With softIoc from base 3.14.12.4 for this DB:

record(ao, "VOLT:set")
{
   field(VAL,  "5")
   field(PINI, "1")
}

record(calcout, "VOLT:calc")
{
   field(OOPT, "When Non-zero")
   field(DOPT, "Use OCAL")
   field(OCAL, "A")
   field(CALC, "1")
   field(OUT,  "VOLT:set")
   field(INPA, "VOLT:req CP")
}

record(ao, "VOLT:req")
{
   field(VAL,  "5")
   field(PINI, "1")
}

I see that the time stamp of VOLT:set does not change when writing to
VOLT:req, but the value changes as expected:

TIME: 2014-09-23 18:04:16.464355407     TPRO: 0             TSE: 0
TSEL:CONSTANT       UDF: 0              VAL: 5

TIME: 2014-09-23 18:04:16.464355407     TPRO: 0             TSE: 0
TSEL:CONSTANT       UDF: 0              VAL: 2

TIME: 2014-09-23 18:04:16.464355407     TPRO: 0             TSE: 0
TSEL:CONSTANT       UDF: 0              VAL: 0

after IOC initialization, caput VOLT:req 2, and caput VOLT:req 0
respectively.

The time stamps of VOLT:calc and VOLT:req are updated as expected.

Can anybody reproduce this behavior?

Best regards,
Michael Ritzert
