Adages become adages by their very nature of being generally true. I was reminded of this again by a friend with a cleaning business who frequently gets asked what he uses to get windows so clean. His usual answer? “Soap and water. And a lot of practice.” I haven’t heard a more succinct demonstration of “It’s not what you do, but how you do it” in some time.
That same adage could be applied to so many thermal processes — and thermal processing equipment. The Industrial Internet of Things is pushing process control into the cloud, where real-time data can be accessed and managed from anywhere (provided you have access to the network). This is a positive advancement that comes with the essential caveat that network security is vital. In fact, to help you do that, in “Secure Remote Monitoring and Supervisory Control,” Bob McIlvride, the director of communications with Skkynet Cloud Systems Inc., Mississauga, Ontario, offers advice on process network security. Dealing with data protocols, machine-to-machine communications and alternatives to virtual private networks for industrial process controls are among the insights he offers.
