Forwarding because Reply All doesn't work and I forgot to add tech-talk.  Grrrr.

The error message you are seeing is misleading, due to an error in PIasynController.cpp.  It contains these lines:


m_pGCSController = PIGCSController::CreateGCSController(pInterface, inputBuff);
if (NULL == m_pGCSController)
{
asynPrint(pAsynCom, ASYN_TRACE_ERROR|ASYN_TRACE_FLOW,
  "PIasynController: unknown controller type %s: %s\n",
  asynPort, inputBuff);
return;
}



So it is reporting the asynPort as the controller type, not the actual controller type.  But this error means that PIGCSController::CreateGCSController failed and returned null.  This is that code:


/**
 *  create instance of GCS controller depending on identification (\a szIDN)
 */
PIGCSController* PIGCSController::CreateGCSController(PIInterface* pInterface, const char* szIDN)
{
if ( strstr(szIDN, "C-663") != NULL
|| strstr(szIDN, "C-863") != NULL
|| strstr(szIDN, "C-867") != NULL
|| strstr(szIDN, "C-884") != NULL
|| strstr(szIDN, "E-861") != NULL
|| strstr(szIDN, "E-871") != NULL
|| strstr(szIDN, "E-873") != NULL
)
{
return new PIGCSMotorController(pInterface, szIDN);
}
else if ( strstr(szIDN, "E-517") != NULL)
{
return new PIE517Controller(pInterface, szIDN);
}
else if ( strstr(szIDN, "E-753") != NULL
|| strstr(szIDN, "E-709") != NULL
|| strstr(szIDN, "E-712") != NULL
|| strstr(szIDN, "E-725") != NULL
|| strstr(szIDN, "E-727") != NULL
)
{
return new PIGCSPiezoController(pInterface, szIDN);
}
else if ( strstr(szIDN, "E-755") != NULL)
{
return new PIE755Controller(pInterface, szIDN);
}
else if ( strstr(szIDN, "C-702") != NULL)
{
return new PIC702Controller(pInterface, szIDN);
}
else if ( strstr(szIDN, "HEXAPOD") != NULL
|| strstr(szIDN, "F-HEX") != NULL
|| strstr(szIDN, "F-206") != NULL
|| strstr(szIDN, "M-8") != NULL
|| strstr(szIDN, "C-887") != NULL
)
{
if (IsGCS2(pInterface))
{
return new PIGCS2_HexapodController(pInterface, szIDN);
}
else
{
return new PIHexapodController(pInterface, szIDN);
}
}
else
{
return NULL;
}
}


Note that the szIDN string error message you see does include the string E-712 so it should have returned:

return new PIGCSPiezoController(pInterface, szIDN);

For some reason that is failing.  You will need to debug to figure out why, I can't spot the problem.  The constructors for PIGCSPiezoController and its base class are very simple, and do not throw exceptions that I can see.

Hi,
    I used the PIGCS2Src in motor-6-8 to drive the PI E712 piezomotor controller.
    But there are two error messages as starting up
1.PIasynController: unknown controller type e712
2.writeFloat64() GCS controller not initialized!

 And the detail of the startup message is following:
