Schneider M241 Series PLC Basic Tutorial
The M241 series programmable controller based on the SoMachine V4 platform is suitable for high-performance machine control with motion control functions. It has a high-speed dual-core CPU processor and leads the market in performance; the main body has built-in high-speed counting and pulse output; it has strong communication capabilities and supports Ethernet. , CANOpen, serial communication, and TM4 communication expansion module can be selected separately; TM3 expansion is adopted, and its speed is 10 times that of TM2, and it supports SD card, TMC4 expansion board, etc., tailor-made for OEM customers.
This course is based on the M241 series PLC, around Schneider Electric's hardware application environment based on the SoMachine control platform, and gradually expands horizontally and vertically from the introduction of the hardware, that is, to understand the relevant knowledge of the hardware, such as hardware configuration, expansion capabilities, and program selection. It also introduces the common sense of related hardware configuration methods and installation and wiring; for future system application upgrade needs, it also explains in detail how to update the PLC operating system, which is what we often call firmware update.
In the SoMachine programming environment, the installation and registration of the SoMachine software platform are introduced step by step, and the common setting options and their meanings of the software platform are involved in the middle; the program conversion of different controllers between different projects is also introduced in detail and Implementation method; Based on the SoMachine software platform, it explains in detail the basic knowledge of the communication connection of the controller, the definition and application of the variable table, the definition and application of the program organization unit (POU), the definition and application of the physical address, etc. Starting from the initial basic application, slowly guide into the actual programming work of the project.
The programming method of the SoMachine software platform is based on the IEC61131 standard, so that the design and programming of the machine control is not limited to one programming method, nor is it limited to only programming the logic state. According to the process requirements, the structure can be planned in the form of sequential flow chart (SFC), the complex process calculation and adjustment calculation can be carried out in the form of structured text (ST), and various logic and process can be processed in the form of ladder diagram (LD). The function block diagram (FBD) is used to repeatedly call the same function and build the communication function and axis control function.
In basic and advanced courses, for programming, the advantages and usage methods of various programming languages, the application of basic programming instructions, the definition and application of function blocks, the definition and application of structures, etc. are introduced in detail; in terms of practical application, Commonly used to read and set PLC clock, serial port configuration and various applications, how to add third-party equipment and common troubleshooting, programming skills, application of library files and curve recording functions, network and bus communication, high-speed counting and high-speed pulse The output and so on are also explained in detail one by one.
