We run virtual machines from ‘toasters’ in our production area which run Ignition clients to control our machinery and systems. This is nice because it reduces the cost of hardware.
The problem with this over physical computers at the location is that I have no way of making sure that the person using the Ignition controls is physically at the piece of machinery - a bit of a safety concern.
Has anyone come across something like this? Anyone have any ideas to solve this? My first thought is a USB drive connected to the toaster that contains a file that I check for the existence of before allowing controls with such safety concerns.
