♥️ 🎓 🍨 WinCC OA tutorial. Part 1. Creating a project and the para module 👩🏼‍🎤 👲 🧔

I decided to tell a little about the visualization system from Siemens called WinCC OA. This SCADA is much less widespread on the Russian market than the classic versions of WinCC (and tia-portal ones too), there is little knowledge about it in the public domain, knowledge is shared reluctantly. In some respects, WinCC OA is radically different from conventional SCADA systems, so first you need to learn the basics.

Before assimilating this basis, I recommend that you familiarize yourself in general with the WinCC OA build architecture. The best way to do this is to find recordings of webinars and speeches by Andrey Kondrashkin, WinCC OA expert, on the Internet. Andrey Gennadievich is a very powerful specialist and an excellent speaker. This cycle of notes, in fact, is based on his two-day introductory training. I recommend this post .

You can go deeper into the study of the issue and further, for example - get acquainted with the SmartSCADA or Preactor add-ons, but this goes very far beyond the basic understanding of the system. The most important thing to take away from this video is an understanding of the WinCC OA architecture. For example, the fact that the system consists of separate complete functional units, which are called "managers". The manager performs his strictly assigned role. At the heart of the entire system is the event manager (EV). There is a visualization manager, User Interface or ui. There are drivers, for example - s7. There is a script manager, control. All managers communicate with each other via the central EV using the standard TCP / IP protocol, regardless of whether they are located on one physical PC, or spaced across several.

The second important distinguishing feature that needs to be understood. OA is an event-driven system. It has almost no constant polling of data. The readings on the operator's screen will change only if the value of the corresponding variable in the controller changes.

Third. All or almost everything is implemented by scripts ("What cannot be programmed in Assembler, you can solder" (c)) and text files. Need to light a mimic light? Script. Moreover, a script that is tied to a change in a variable and performs certain actions only on this change automatically.
