Innovative solution for
shutting down Industrial
PCs
Industrial PCs equipped with a UPS are in actual use frequently switched
off by simply turning off the supply voltage. In this case the PC shuts down
via the battery. However, over time this reduces the service life of the
battery.
The new Beckhoff power supply technology approach addresses this
problem and now offers the user the option of switching the PC off without
the need for using the battery, thereby reducing the load on the battery.
In addition to the main switch this innovative solution uses an ON/OFF
switch for the machine. Basically, the main switch remains switched on and
provides the power supply for the PC during shutdown. Via the PC ON-
input of the power supply the PC gets the command to shut down the
operating system.
Once the PC has shut down, the PC power supply unit sets the Power
Status-output (P-S) to 0, what indicates that the process is complete and
that the main voltage can be switched off. This can be done manually via a
