Hi Zongyang,

What version of the motor record are you using?  The current master branch of the motor record does not contain a field called CENE.

https://github.com/epics-modules/motor/blob/master/motorApp/MotorSrc/motorRecord.dbd

Is this something that was locally added to the motor record?

Mark

Hi,

I is writing motor device driver based on Model 3.

But I meet some problem which about rewriting WriteInt32 (asynUser *pasynUser, epicsInt32 value) function.

However, I changed the value of $(motor).CENE field in motor OPI, my WriteInt32()  function cann’t be called.

And the value of other fields changed can call this function.

My WriteInt32() function is  as follow:

------------------------------------------

asynStatus PDICLController::writeInt32(asynUser* pasynUser, epicsInt32 value)

{

       int function = pasynUser->reason;

       int status = asynSuccess;

       PDICLAxis* pAxis;

       static const char* functionName = "writeInt32";

       pAxis = this->getAxis(pasynUser);

       if (!pAxis) return asynError;

       status = pAxis->setIntegerParam(function, value);

       epicsPrintf("test :104 line :The function name:%d and the value :%d\n",function,value);

       if (function == PDICLJoggingPosMethod_)

       {

              if(value!=0)

              {

                     status = pAxis->Jogging_move_pos();

              }

       }

       if (function == PDICLJoggingNegMethod_)

       {

              if(value!=0)

              {

                 status = pAxis->Jogging_move_neg();

              }

       }

       else {

              // Call base class method

              status = asynMotorController::writeInt32(pasynUser, value);

       }

       pAxis->callParamCallbacks();

       return (asynStatus)status;

}

-------------------------

When I change the state of $(motor).CENE field , just the motorUpdateStatus_ function that is called which mark is 26

and the motorClosedLoop_ function cann’t be called which mark is 19.

Mennwhile I test the motorStop_ function which mark is 4.

The test result of the shell of ioc is as follow

-------------------------

epics> test :104 line :The function name:26 and the value :0

test :104 line :The function name:4 and the value :0

test :104 line :The function name:26 and the value :0

test :104 line :The function name:26 and the value :0

-------------------------

I see other motor module’s device driver have done as same.

What’s going wrong about my code?

Any suggestions or comments would be appreciated.

Best regards!
