Special Guide

S7-300 is a mid-range product of Siemens PLC. It has a modular structure and is easy to implement distributed configuration. It also has many advantages such as high cost performance, strong electromagnetic compatibility, and good shock resistance. Of various fields. In this special topic, we have specially compiled the selection samples, programming manuals, installation software and related parameter settings, and usage guides of Siemens S7-300 PLC. I hope it can be helpful to colleagues!

Highlights
  • The data mainly introduces the technical specifications of each component module of the S7-300 PLC, order data, and related module connection methods, etc., for reference when selecting models.

  • This document introduces the PLC status failure judgment, mode selection switch, basic PLC operation instructions and switch analog program design application that need to pay attention to when learning S7-300 PLC programming, for reference during programming.

  • The data mainly includes the valid range of the S7-300 PLC instruction list, registers, addressing examples, calculation pointer examples, using the CPU 314C-2 DP to calculate execution time, instruction lists, etc., which can be used for programming reference.

  • The data introduces the CPU classification, function modules, programming languages, instruction systems, parameter settings and related program design methods of the S7-300 PLC.

  • A complete overview of how to use STEP 7? How do you create a program and describe the components of a user program? For people using STEP 7 and SIMATIC S7 automation systems for control tasks.

  • The materials mainly include S7-300 / 400 PLC various instruction descriptions, a list of all statement list instructions, programming examples, parameter transfer, etc., which can be used for programming learning.

  • The data mainly includes the S7 300 PLC storage area overview, S7-300 CPU classification, data retention, etc., which can be used for reference when selecting and using.

  • The document contains the relevant installation files of Siemens S7-300 programming software, which can be downloaded and installed for free.

  • The data is based on the S7-300 CPU connected to the RF180C communication module via Profinet as an example. The RF340R reader is operated to read and write the RF340T tags for reference.

  • The main communication methods in Siemens control products are MPI, Profibus, and Ethernet. In field applications, controllers from two manufacturers are often required to communicate and exchange data. Modbus communication is a commonly used one. This article introduces CP341 as a Modbus master station and S7-200 as a Modbus slave station communication experiment.

  • The material mainly includes the working principle of S7-300 / 400 PLC software redundancy, software redundancy blocks and specific cases of implementing software redundancy through PLC, which can be used for reference.

  • The materials use the Portal V13 SP1 Update4 software environment, hardware products such as S7-300 CPU315-2PN / DP, ASM456, RF340R, and RF340T. This article briefly introduces the project upgrade and equipment replacement of the RFID processing program for S7-300 / 400 on the TIA Portal platform , Parameter configuration and other operations; using FC45 as an example, briefly introduces the use of S7-300 to read and write data on RFID tags.
