Industrial communication refers to a category of products and solutions designed for reliable data exchange in industrial environments, rather than a specific brand. Key players in this field include Siemens (Germany), Rockwell Automation (USA), and Schneider Electric (France). These companies provide industrial Ethernet switches, fieldbus systems, wireless modules, and protocol converters that enable machine-to-machine communication in manufacturing, energy, and transportation sectors. For example, Siemens' PROFINET and Rockwell's EtherNet/IP are widely adopted industrial Ethernet protocols. Specialist distributors like Radwell and Grainger supply components from these manufacturers to maintain automation networks across industries.
