Watch this video for a detailed explanation of the Project Explorer structure, which includes different levels. It is important to understand the structure of Selmo in order to successfully implement your projects.
The top level, the plant, represents the overall system and always contains a sub-level. This sub-level, the hardware zone, can contain one or more sequences. A sequence defines a logical process description and consists of the Logic Layer (logical process description in the form of a step chain), MXIC (interlocks in manual mode) and CMZ (continuously monitored zones).
The Plant describes the machine that manufactures a product. It consists of several units that work in a specific sequence to produce something. The hardware zone (HWZ) describes a specific part of the machine that has separate automatic and manual controls.
The sequence defines the logical sequence of a machine step chain and consists of the Logic Layer, System Layer and Assembly Layer. The system setup with Selmo always follows the same structure.
The logic layer contains the functional requirements for the machine; the logical process is also defined in this layer. The system layer contains the technical aspects and the interfaces to other systems. The assembly layer, on the other hand, contains ready-made function modules or components and is an abstract layer that lies between the actual application logic and the hardware, thus saving developers time and energy.
This video provides a detailed explanation of how these levels work together to define the logical flow of a machine. Once you understand this structure, you will be able to effectively analyze and optimize complex production processes. This will help you improve the processes in your projects.
In the next video, we will take a closer look at the sequence level. Stay tuned for more insights!
