Hello all. Im trying to use the asyn module to associate the value of a PV to the value of a variable inside my cpp code.

The PV is defined as:

record(mbbo, "$(P)$(BE)DynamicRange"){

field(DTYP, "asynInt32")

field(ONVL, "1")

field(ONST, "Full Dynamic Range")

field(ZRVL, "0")

field(ZRST, "Default")

field(OUT, "@asyn($(PORT),$(ADDR=0),$(TIMEOUT=1))DYNAMIC_RANGE")

}

In my header file i have:

#define DynamicRangeString "DYNAMIC_RANGE"

int DynamicRangeString_;

and inside my .cpp:

createParam(DynamicRangeString, asynParamInt32, &DynamicRangeString_);

asynStatus Mobipix::writeInt32(asynUser *pasynUser, epicsInt32 value)
{

(...)

printf("test");

}

When i dbpf into other asyn mbbo records that come from ADBase.template, such as "$(P)$(R)FrameType", the ioc shell prints the test message. When i dbpf into my DynamicRange PV nothing happens.

What am i missing?

Thanks for the help,

Marco
