About the book: 2023 / This book offers an alternative method of creating programs for programmable logic controllers - PLCs. The method of controlling controllers using programs organized in the form of tables is considered. Using tables allows you to monitor the execution of a program in the controller, without connecting it to a computer with the development environment installed. The use of table programming for equipment control can simplify the development of programs for PLCs, speed up troubleshooting, significantly reduce downtime, and also significantly reduce the cost of equipment and software. The book discusses the basics and features of spreadsheet programming, as well as examples of solving automation problems using spreadsheet programs. Additionally, a simple environment for developing programs organized in the form of tables is presented..
