Interest in using cloud computing — also known as Software as a Service (SaaS) — to provide remote access to industrial systems continues to rise. Vendors and company personnel alike point to potential productivity improvements and cost savings as well as convenience. Operators and plant engineers may want to receive alarms and adjust heating controls while moving around the plant. Managers would like to see production data in real time — not just in end-of-shift or daily reports. Hardware vendors could benefit from getting live readings from their installed equipment for maintenance and troubleshooting operations.
Some industrial processors are attempting to provide this kind of window into their production systems. Yet, many question the wisdom of opening up a plant’s mission-critical control network to the possibility of malicious attack or even misguided errors. With a proper understanding of what is at stake, what is being proposed and how it can best be implemented, you can better decide whether remote access to your production data could benefit your company.
