I've been spoiled by Ethernet/IP. Recently started using some Vision Cameras and Barcode readers that communicate via Ethernet/IP with a CompactLogix. Was very fast and easy.
But it came up recently that they wanted people to log into machines using their employee badges. Each employee carries a badge that has a magnetic strip they use to punch in/out for work. Certain employees would have more access to machine settings, etc, than others. Passwords are used currently, but people share passwords very often, and before we know it, everyone and their mothers know the password.
I've been looking around a bit to see if anyone made a card reader that was Ethernet/IP, since that feature would make things so much easier to use. I want to avoid RS232 because not all of my PLCs have that option. Has anyone used something like that in the past?
