Traffic signals are a regular feature in industrial or construction sites. In this article, we take RevPi Core3 as an example, and use an industrial-grade Raspberry Pi as a soft PLC, programmed with Logi.CAD 3, to create a stable and reliable application facility.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

PLCs are specifically designed to control manufacturing processes and can be programmed more easily using a standard set of instructions. They were originally developed in the automotive manufacturing industry to replace a complex, hard-wired collection of relays, timers, and sequencers that previously controlled manufacturing processes and were difficult to update.<\/p>\n\n\n\n

Today, the RevPi Industrial Raspberry Pi is a modular system with protected inputs and outputs in a ruggedized industrial package that leverages the Raspberry Pi's extensive ecosystem and software support, combined with a programmable PLC that complies with the IEC 61131 industry standard for DIN-rail mounting.<\/p>\n\n\n\n

    Like most PLCs, the Revolution Pi is programmed on a PC and then downloaded to the module over the network. Programs can be downloaded to the module via the network by going toKunbus Quick Start Guide<\/a>CAD 3 to see how to create a control application for Revolution Pi using logi.CAD 3 and get a link to download the software.<\/p>\n\n\n\n
