+1. We always have PCs in the control room for email, generating tags and other documentation, etc. This also makes me think again about thin-client solutions. I suspect that those thin-client boxes either don't have USB ports, or they can be configured not to transmit back to the server :) Corey From: "Russ Kaiser" <russ@xxxxxxxxxxxxxxxxxx> To: <foxboro@xxxxxxxxxxxxx> Date: 03/23/2011 03:19 PM Subject: Re: [foxboro] Windsnows Question Sent by: foxboro-bounce@xxxxxxxxxxxxx Joking aside, at our facility a mouse will occasionally go bat-$#|+ and the operators will unplug it and plug it back in fixing the problem. They also have access to the spare mice and keyboards. The fact that they are willing to do this at 4 AM instead of calling me is very convenient. We have also given them a computer (off the control network) they can log into individually with controlled internet access. They know the sites they visit are monitored, and many types of sites are blocked, and they behave accordingly. If they want to slip a thumb drive into the computer and show their fellow operators the fish they caught on their last vacation they can. They all have plenty of work to do and for the most part I don't think anyone abuses these privileges - division of labor and peer pressure would prevent it. The computer is running antivirus of course and they can't install software. Sometimes the best thing to do is to trust. I know some of you probably operate in facilities where regulations or the product you are making makes this arrangement impossible, but if you don't, you might try it. Giving them a computer keeps them from messing with the control system boxes.
