3BHB003688R0001 PLC Hardware and Software

3BHB003688R0001 series PLC hardware and software is powerful, modular design, easy system configuration, in a rack chassis can be installed on the power supply, CPU, a variety of signal templates, communication processors, and other special function modules, a variety of modules are easy to install, the system with a powerful Profibus fieldbus interface and MPI interface, MPI interface is both programming interface and data communication interface, through this interface between PLC and PLC, or between PLC and host computer can be communicated through the MPI protocol, thus forming a MPI network. The MPI interface is both a programming interface and a data communication interface, through which PLC and PLC, or PLC and the host computer can communicate with each other through the MPI protocol, thus forming an MPI network. However, the S7-300 series PLC comes with the configuration function, far from meeting the customer’s requirements, the visualization effect is poor, naturally, it needs to be matched with the configuration software to achieve its monitoring function.

3BHB003688R0001 to perform hardware configuration. At this time, the computer as a PLC programming device, open the S7-300 programming software package STEP 7, S7-300 rack number, power supply, CPU, distributed I / O and other modules, according to their actual physical location for the configuration, which, distributed I / O module address is generally set according to the dial switch next to the module. Finally, the configuration program table is downloaded to the PLC and confirmed. In the Siemens software package STEP7, ladder diagrams, statement tables or function block diagrams can be used for programming.

3BHB003688R0001 The analysis and design methods in automatic control theory are mainly based on a linear constant mathematical model of the controlled object. The model ignores the nonlinearity and time-varying nature of the actual system, and there is a large gap with the actual system. For many industrial control objects, it is simply impossible to establish a more accurate mathematical model, so the design methods in automatic control theory are difficult to use for most control systems.
