-GEM300 standards consist of state models.  This [[Intel transcript|https://slideplayer.com/slide/13207475/]] provides an overview.+GEM300 standards consist of state models.  This [[https://slideplayer.com/slide/13207475/|Intel transcript]] provides an overview. As you move product, or carriers through your tool the control system must update the current state to ensure that the host can correctly manage tool operation. 
 + 
 +Implementation of these standards will require reference to the appropriate standard and state model in the standard.  The implementations will vary based on your needs and the capabilities of the tool.  A wide range of possible scenarios are provide in the SEMATECH document [[https://www.ergotech.com/files/guides/ISMI%20Operational%20Flows%20and%20Scenarios.pdf|300 mm Operational Flowcharts and Scenarios, V. 10]] 
 + 
 +===== TransSECS implementation ===== 
 + 
 + 
 +In all the TransSECS GEM300 implementations there are two, fundamental part.   
 + 
 +  - "Callback" interface - this is how you are notified of the host's requests 
 +  - "Service Wrapper" - this is how you indicate that changes at the tool. 
 + 
 +Individual standards have other components, E40 Process Jobs, E87 Carriers, E90 Substrates, E94 Control Jobs, etc. 
 + 
 +**Note:** You do not need to implement, or parse SECS messages.  This is all done for you within the interface.  Do not add GEM300 messages to the TransSECS interface. 
 + 
 +==== E39 ==== 
 + 
 +E39 is a required standard to support GEM300, however the implementation and operation of E39 is completely transparent to the TransSECS GEM300 operation.  You need only initiailize the interface. 
 + 
 +==== E40 ==== 
 + 
 +Provides a model of the process state within the tool, primarily through the management of "Process Jobs".  A Process Job is created by the host, or on rare occasions by the tool.  In a simple example, the process job may go through the following steps: 
 + 
 +  * Allocated - state transition 2 - the Process Job is removed from the queue in preparation for execution - processJob.allocated(); 
 +  * Material Arrived - no state transition - indicate that the material for the Process Job is at the tool - processJob.materialArrived(); 
 +  * Start the Job - state transition 4 - start execution of the Process Job - processJob.readyToStart();  (Note: If the process job is not set to start automatically a "Start" command will be required from the host - see below). 
 +  * Processing Complete - state transition 6 - The material processing is complete - processJob.complete(); 
 +  * Material Departed - state transition 7 - The material has been removed from the tool.  The process job is complete and will be deleted - processJob.materialDeparted(); 
 +  *  
 +=== E40 Service Wrapper === 
 + 
 +The E40 Service Wrapper provides access to control the flow of E40.  Most importantly, it provides access to the individual Process Jobs. 
 + 
 +A listing of all process jobs is provided by: 
 +<code> 
 +E40ServiceWrapper.getInstance().getAllPRJobs(); 
 +</code> 
 +A particular process job can be obtained by the job id: 
 +<code> 
 +E40ServiceWrapper.getInstance().getPRJob(jobID) 
 +</code> 
 + 
 +=== E40 Callback Interface === 
 + 
 +The E40 Callback Interface provides notification of activity from the host.  There are four methods: 
 + 
 + prStateChange : function (prJob, oldState, newState) 
 +  Indicates that the state of a process job has change. 
 + prJobCreate : function (prJob) 
 +  A request to create a process job.  No action is required if the creation of the process job is acceptable.  If not, throw an E40Exception with the reason it's not acceptable.   prSetRecipeVariable : function (prJob, recVarList) 
 +  This method provides recipe variable.  Support is option, if supported this must set the provided recipe variables on the job id. 
 + prSetMtrlOrder : function (prCurrentMtrlOrder, prNewMtrlOrder) 
 +    Set the order in which process jobs should be processed. Possible options are: 
 +  1 = ARRIVAL   process whichever material first arrives 
 +  2 = OPTIMIZE   process in an order that maximizes throughput 
 +  3 = LIST   follow the order in the list  
 + prCommandCallback : function (prJob, prCmd, prCmdParameterList) 
 +    Called when the host requests that a command be executed on the process job. Possible commands are ABORT,STOP,CANCEL,PAUSE,RESUME,STARTPROCESS 
 +    Only ABORT must be supported. If the command is not supported, throw an E40Exception 
 +

 +  // first indicate which process job the command is being executed on

 +      } 
 +  } 
 +   
 +  // get the index of the command 
 +  cmdId = cmds.indexOf(prCmd); 
 +  /GEM300PLC/PrCmd->setIntValue(cmdId); 
 + } 
 +  }; 
 +   
 + /// START OF MAIN JAVASCRIPT CODE /// 
 +print("Register GEM300"); 
 +  
 +    var controller = null; 
 +    do {  
 +        //print("host is still null");   
 +        Thread.sleep(50); //wait 50 ms 
 +        controller = TransSecsController.findController("GEM300PLCTool"); 
 +    } while (controller == null); 
 +       
 +    try { 
 +        E39MessageHandler.addMessageHandler(controller.getControllerName()); 
 +        E40MessageHandler.addMessageHandler();

 +        print (e); 
 +    } 
 +    E40ServiceWrapper.getInstance().registerCallback(E40Callback); 
 +     
 +    print("E40 Registered"); 
 +    
 +    
 + 
 +  
 +</code> 
 + 
 +As noted above, if the process job is not set to auto start, you will need to start the job at the tool after the host sends the start command.  In this case, you may want to check the transition to "PROCESSING" in the state change function.  Here's a quick code snippet. 
 +<code> 
 + prStateChange : function (prJob, oldState, newState) { 
 + 
 +   if (newState ==  ProcessJobStates.PROCESSING.getStateId() && oldState == ProcessJobStates.WAITINGFORSTART.getStateId() ) { 
 +      // send the commands to the control system to start executing the process job 
 +   } 
 +    // similar checks may be needed for transitions from PAUSED 
 +    // additional state-change related code. 
 +   
 + } 
 +</code> 
 +==== E40 Java Example ==== 
 +=== E40 Java Using the Service wrapper calls to process a job === 
 +Executing a job through E40 requires indicating to the process job the current state of the process. For example: 
 +<code java> 
 +Initialize the handlers: 
 +    try { 
 +      E39MessageHandler.addMessageHandler(equipmentController.getControllerName()); 
 +      E40MessageHandler.addMessageHandler(); 
 +      E94MessageHandler.addMessageHandler(); 
 +      E87MessageHandler.addMessageHandler(2,4); 
 +    } catch (BadParameterException e) { 
 +      e.printStackTrace(); 
 +    } 
 +    E40ServiceWrapper.getInstance().registerCallback(new E40Callback()); 
 +[...] 
 + /** Process a Job. */ 
 +  protected void processJob() { 
 +    ProcessJob[] allProcessJobs = E40ServiceWrapper.getInstance().getAllPRJobs(); 
 +    if ( allProcessJobs.length > 0 ) { 
 +      ProcessJob processJob = allProcessJobs[0]; 
 +      processJob.allocated(); 
 +      processJob.materialArrived(); 
 +      wait500(); 
 +      processJob.readyToStart(); 
 +      while ( processJob.getPrJobState() == ProcessJobStates.WAITINGFORSTART.getStateId() ) { 
 +        wait500(); 
 +      } 
 +      wait500();    
 +      try { 
 +        processJob.complete(); 
 +        processJob.materialDeparted();

 +==== E94 ==== 
 + 
 +Provides a model of a "Control Job".  Control Jobs are created and managed by the host, or on rare occasions by the tool.  Control Jobs contain Process Jobs (E40) which perform that actual processing of product. 
 + 
 +=== E94 Service Wrapper === 
 + 
 +The E94 Service Wrapper provides access to control the flow of E94, however there are no actions required by the tool controller to manage a control job. 
 + 
 +=== E94 Callback Interface === 
 + 
 +The E94 Callback Interface provides notification of activity from the host.  A sample implementation of the interface is provided below. The tool control system should implement as many of the methods are required to progress the Control Job through the tool.  Each of the control job actions acts on the underling Process Jobs.

 + 
 +==== E87 ==== 
 + 
 +Provides control of a carrier.  Carriers can be entered manually or automatically and can be verified at the tool - for example by reading an RFID tag, or by the host.  The slot map of the carrier can be read by the tool and verified by the host or provided by the host. 
 + 
 +=== E87 Service Wrapper === 
 + 
 +The E87 Service Wrapper provides access to control the flow of E87.  Because there are many paths through the tool, E87 must provide for all these options, however, a particular tool is unlikely to require all the features.  A basic flow, might looks something like this 
 + 
 +<code> 
 +      e87ServiceWrapper = E87ServiceWrapper.getInstance(); 
 +        // mark the carrier as arrived... 
 +        e87ServiceWrapper.carrierArrived(carrier.getCarrierId(), carrier.getLoadPortId(), true, false); 
 + 
 +      // set the slot map.  This slot map and the host slotmap will match 
 +      carrier.setSlotMap(slotMap);  // transition 11 - the host and equipment slot map match. 
 +      if ( carrier.getSlotMapStatus().getIntValue() != Carrier.SlotMapE87State.SLOT_MAP_VERIFICATION_OK.getSlotmapE87StateId() ) { 
 +        System.out.println ("Failed To Verify SlotMap"); 
 +      } 
 + 
 +      // start processing the carrier 
 +      e87ServiceWrapper.accessCarrier(carrier.getCarrierId(), Carrier.CarrierAccessE87State.IN_ACCESS); 
 +      wait500(); 
 +      // carrier access is complete 
 +      e87ServiceWrapper.accessCarrier(carrier.getCarrierId(), Carrier.CarrierAccessE87State.CARRIER_COMPLETE); 
 +      // ending access is not the same as the carrier being ready to unload.   
 +      e87ServiceWrapper.setLoadPortTransferState(1,9);  // transition the load port to "ready to unload" 
 +      wait500(); 
 +      // when unloading starts (manual or auto) transition to "TransferBlocked - 7 
 +      e87ServiceWrapper.setLoadPortTransferState(1,7);  // transition the load port to "ready to unload" 
 +      //carrier.transition21(); // carrier is removed from tool 
 +      // could also be the "cancelBind" service which simply executes transition21 after verifying the carrier and port. 
 +      //e87ServiceWrapper.cancelBind(carrier.getLoadPortId(),carrier.getCarrierId()); 
 +      // carrier has departed 
 +      e87ServiceWrapper.carrierDeparted(carrier.getLoadPortId(), carrier.getCarrierId());
