The term 'Open' has become ubiquitous in industrial automation, but its meaning is often vague. It encompasses various measures, and suppliers may be open in some aspects while closed in others. Buyers should ask specific questions to discern the true openness of a platform or system.
Historically, Open Automation 1.0 focused on interoperability, allowing different systems to communicate without custom drivers. With standards like OPC UA and MQTT, this challenge has largely been addressed. Open Automation 2.0 shifts the focus to application freedom, enabling users to run third-party software on devices, which enhances flexibility and reduces costs.
As suppliers navigate the balance between openness and security, buyers must recognize that openness involves trade-offs. While opening systems can increase vulnerability, established standards like ISA/IEC 62443 provide frameworks for maintaining security. Understanding these dynamics is crucial for making informed decisions in industrial automation.
Editor's Note
The concept of 'openness' in industrial automation is critical for enabling interoperability and flexibility. As companies increasingly adopt open standards, understanding the nuances of what 'open' entails becomes essential for procurement professionals and decision-makers. This knowledge can drive better investment choices and enhance operational efficiency.
