Too often I find that there is a need to lock out all motors, etc on a machine with a single disconnect, yet I don't want to power down the PLC and/or the HMI computer. The fact that they have to logout, shut down the computer, and then reboot and log back in when they are done IMO actually discourages the operators from using proper lockout/tagout procedures when doing maintenance that should require it. I have been known to put two disconnects on an enclosure, one to kill everything and one to kill only whatever is necessary to render the machine safe.
Just curious to hear what you all do.
