Alternatives to OPC (Open Platform Communications) in industrial automation and IT/OT integration include lightweight messaging protocols, specialized communication frameworks, and software-based data integrators. MQTT (with Sparkplug) is the most popular alternative for IIoT due to its lightweight nature, while Woopsa acts as a simpler, HTTP-based option. Other options include direct driver integration, API-based, or low-code alternatives.
