Hi. Take a look at this tip link (PCS7 Complete overview) posted at the top of this Conference by Oreca. Very interesting material to clarify your mind...

Uhm.....EVERYTHING except real hardware connections. As of PCS7 8.0 there are new options regarding simulation: Internal and external simulation. Internal simulation can be done on all technological blocks like a valve, motor etc. You can simulate on the faceplate as well in CFC/SFC. Block external simulation is done by manipulating signals like a feedback open or feedback close signal. Not using real IO is not an issue anymore. For this you can use a software called SIMIT. Simit allows you to create a real simulation, where hardware IO can be connected. But this involves weeks of learning. See the following link to provide you with examples and add-ons for PCS7: https://support.industry.siemens.com/cs/document/63481413/simatic-pcs-7-overview?dti=0&lc=en-WW Maybe you can tell me what you want to do exactly? |

Hold on, you're not getting of easily As a feature control engineer, you can check a few examples. I suggest you take a look at the section: Advanced Process Control, which is in the link Berg and I gave you. To check examples of a few processes, please check section: PCS7 Unit templates. I don't think you want to develop a simple equipment module, like filling a tank to a specific level and maintain the level. I think you need to do something with split range control, model predictive control, Smith predictor and such. Or, maybe you can expand an existing example project like the Fermenter or Dryer. However, it requires knowledge of the APL library (assuming you will use latest PCS7 version 8.1, or at least >8.0. Good luck! |

Thanks... What type of control could I use? Robust? Adaptive? Sliding mode? Could I use them with PCS7? Best Regards |

There is an adaptive controller, that I know off, I'm sure there is something for sliding modes and stuff as well. Enclosed is a link with info. See page 26 for the adaptive controller. I cannot upload the PDF file, but check the following link: Add ons PCS7 |
