17. Unicos Object Library Programming Templates IO Error / IO Simulated and Tracking for Controller Object (PID)  IOError --> IO Error Warning (IOErrorW) from the Hardware measured value (Analog Input Object from Premium) or IO Error Warning from the Controlled Object (Analog Object in Quantum)  IOSimu --> IO Simulated Warning (IOSimuW) or Forced Mode (FoMoSt) from the Hardware measured value (Analog Input Object from Premium) or IO Error Warning (IOErrorW) or Forced Mode (FoMoSt) or Manual Mode (MMoSt) from the Controlled Object (Analog Object in Quantum) or Forced Mode (FoMoSt) from Analog Output Object.  Auto Tracking Request (AuTR) input of the Controller Object is activated when the Controlled Analog Object is in Manual or Forced Mode or when the Analog Output Object is in Forced Mode (FoMoSt). The PID output tracks then the Hardware Analog Output Order (HOutO) requested by the operator. This avoids bump on the Output Order when the Forced Object is released in Auto Mode. Analog Output Order is connected to Position Status of the Analog Output Object.

27. Unicos Object Library Programming Templates Auto Mode Request Propagation  When starting a process part using high level PCO, all dependent objects have to be in Auto Mode. If some objects are in manual or forced mode, they will not respond to the program request.  PCO Objects have the possibility to propagate the Auto Mode Request to the dependent objects with the output AuDeSt. AuDeSt is the result of either a Manual Request from the faceplate in supervision or the input AuDeR of the PCO.  In general, the dependent object are also requested to Auto Mode by the PCO in the following conditions(*): - rising and falling edge of the PCO RunOSt (Run Order) - rising edge of the PCO CStopOSt (Controlled Stop Order)  This feature when programmed correctly allows an operator to put in Auto Mode all objects (except forced) of a whole process part (PCO + dependent objects). * Other conditions may be defined
