This white paper explores how this 'always on' eLearning resource can facilitate technology professionals' ability to increase productivity, pursue professional certifications, and improve collaborations and communication.
New digital technology now makes it feasible to integrate process control and SIF within a common automation infrastructure. While this can provide productivity and asset management benefits, if not done correctly, it can also compromise the safety and security of an industrial operation. Cybersecurity and sabotage vulnerability further accentuate the need for securing the safety instrumented system (SIS).
Certainly, a common platform approach using similar hardware and software dedicated for control and safety functions, respectively, can provide the potential for cost savings. However, it is widely acknowledged that utilizing separate, independent, and diverse hardware/software for safety and control is the optimal way to protect against potentially catastrophic common cause and systematic design and application errors.
Different vendors offer varied degrees of integration and solutions. The question is: how to provide an integrated control and safety solution with advanced functionality and productivity without compromising safety and security? And, where do users draw the line?
A third-party (e.g., TÜV) certification of the hardware/software systems to IEC 61508 specifications carries significant advantages, but should this be the only criterion? How does a third-party certificate extend to the plant’s overall assignment of risk reduction credits for all independent protection layers (IPL)? Control system embedded safety logic solvers may actually increase the SIL requirements of the SIF if no credit is allowed for the distributed control system (DCS) as an IPL.
