Gaining an understanding of the changes in the rapidly evolving industrial wireless sector will be valuable to not only manufacturers but also end users and engineering companies to help determine longer term planning. This annual survey from WINA is a valuable tool to assist in gathering this information.
Here we look at how to make sure the measurement system is able to provide the analysis, metrics, and control needed for process control improvement. Also outlined is the opportunity sizing and assessment process, the use of statistical tools, the tracking down of the source of variability, and the finding...
The past two weeks continue to demonstrate the lack of understanding about the unique issues of ICS cyber security – why isn’t it just IT. This includes the lack of understanding from private industry, DOD, DOE, and academia.
I have been concerned for years that companies have been monitoring corporate networks and extrapolating those results to the ICS networks. I know of only a few companies that have actual monitoring data from their ICS networks. The results are certainly different than those on the corporate networks.
A European standard intended to reduce the likelihood of signal interference in the ISM bands could have a significant impact on how Industrial wireless networks will be designed and operated. Because the standard applies to any device generating above 10mW, it will be relevant to present radio based field sensor networks.
I was in Washington DC to be interviewed for an upcoming TV show on cyber security. We spent about an hour filming in front of two critical infrastructure sites. No one came out to see who we were or ask what we were doing. What if we were bad guys?
Safety systems are an important component of control systems and with the recent publication of the second edition of these documents so getting an understanding of some of the basic changes is certainly something that should be done.
The benefits from process control improvement originate from increases in process efficiency, flexibility, and capacity. Often, there is a tradeoff where an increase in flexibility or capacity is accompanied by a decrease in efficiency. Better measurements, process knowledge, online metrics, and an enhanced PID can provide a more intelligent and effective...
Many ICSs are connected to the Internet and it isn’t expensive to find them. ICSs continue to be connected to the Internet even though they may not be cyber secure. Be careful what you ask for - you just might get it.
