Since many industrial devices are soft targets for hackers, placing smaller firewalls deeper in networks near PLCs or embedding them in such controllers is a practical way to add a higher level of protection.
Whether for traceability, electronic record-keeping, or emissions monitoring, automated controls and software systems help facilities meet regulations—and let control engineers rest easier at night. Regulations involve monitoring...
Soapbox: Don’t settle for faults inherent in PLCs and PCs. Take the best of each for a more effective hybrid system for process control, according to a software and hardware provider to the process industries.
With industrial controls, it is extremely difficult to design sophisticated programs for process and even discrete control that run on multiple devices, often requiring simplification. Open systems help.
