  2. 1.

  3. 1. Network Processes via a Esone Server kp1pc065 (FOPI CS Server) CS CS Events Esone Dispatcher -usese the Labview Esone Driver to communicate with the Server - only the commands cfsa and cdreg seems to work LeCroy 2132 Interface - can read and write Voltages,etc. from a LeCroy 1440 Module Constant Fraction Interface - can read and write values to CF8101 modules - Esone Dispatcher provides single CAMAC CNAF´s from the Labview Event, to the real CNAF - Esone driver is coded in C and only fittet in as ".dll" by a call Libary node - To talk with the esone dispatcher only send the event, that fits your camac-action, for example cfsa - It seem, that only cfsa and cdrag do work correctly, by using other camac functions the esone server get stuck. But by using cfsa i was able to do all nessesary actions TCP/IP Esone Server Camac Bus

  4. 2. The CSPBGroup Object The CSBP Group Object - is for grouping many BaseProcess-Classes - to make talking to them more easy - to give some structure to your Project - and to get rid of the loadProcess procedure testclass test2 CSBPGroup Group2 CSBPGroup Group1 testclass test1 other_class test 3 - "get State" gets also the state of eventually sub Groups, needs no argument - if you send a event to the GroupObject, it will provide it to all its members. - The data array in the answer cluster has the laengt of the number of responses, made by the member objects - you can also create group elements on other nodenames, if the CS there knows the class - if you set the bool in "deleteGroup" the whole Group-tree will also get deleted

  5. 3. Object Nets Radiator - Controll Object Net, made with ObjectView Advantages of Object Nets - the whole Project on one Page - a startup procedure is no longer nesesarry - You can "see" which Objects are talking together - also "LoadProcess" on other Machnines could be implemented, to produce a distributed Object Network Implementation in the CS ?

  6. working with EON (Elemental Object Net´s) - If you want to use EON, you need to build a EON Object for your device Object - Define Events/eventdata, which are able to handle the communication between the EON Objects - Communication via Dim-Events requirements to CS: 1. Seperation of the BaseProcess in: - PeriodicProcess - EventReciverProcess - DatabaseProcess profit : makes it possible to generate Instances of EventReciver Objects programaticly 2. a super Function "Load Object" - with "Data in" as Input - similar to "CSSysem._new.vi" profit : The super Process could now be used as "Object Factory" Device Object Device Layer Application Layer Controll refnum EON Device Object EON Panel Dataflow

  7. 4. Petri Nets Petri Net´s Transition Empty Place Place with Marker - simple modelling of process structures - possibility of Parallelprocesses, sub routines and process loops - easy and fast coding of complicated processes - possibility to make mathematical calculations on the modell, and to simulate all cases Petri Net´s in ObjectVIew

  8. 4. Petri Nets Philosoph problem - every philosoph needs two forks to eat - after eating a bite, the philosoph needs some time for thinking Petri net for two philosophs in Labview
