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! Zongyang yue |
