Switching the industrial PC on and off
Notice | |
Public networks Connecting the PC to public networks without additional protective measures can compromise the safety of the device.

Notice | |
Data loss due to switching off the device while the software is running Switching off the device before the running software is terminated and the operating system is shut down can lead to data loss.
|
Notice | |
Data loss due to switching off the power supply when the UPS battery is empty Switching off the power supply when the UPS battery is empty can lead to data loss, as the operating system cannot be shut down properly without battery power.
|
Notice | |
Shortened battery life due to switching off the power supply If the power supply is simply switched off, the operating system shuts down via the battery. With daily use, this significantly shortens the life of the battery.

Switch on and off with 100-240 V power supply unit
The industrial PC is started or switched off when the system is switched on or off or when the power supply to the industrial PC is connected or disconnected.
If you have ordered your industrial PC with a 110 V or 230 V UPS, this enables data backup in the event of a sudden switch-off of the device. If the power supply or the system is switched off before you have shut down the operating system properly, the operating system shuts down using the battery. Data can be saved. With frequent use, this shortens the life of the battery.
Switching on and off with 24 V power supply unit without UPS
If you have ordered your industrial PC with a 24 V power supply unit without integrated UPS instead of a 100-240 V power supply unit, the industrial PC has a power supply socket (X101) and a socket for external wiring (X102). The socket for external wiring contains an input PC-ON and an output Power Status.
You can use the PC-ON input of the PC to control the startup and shutdown of the operating system. The PC-ON signal is inverted, which is why the operating system boots up at 0 V at the input and shuts down at 24 V. During operation, 0 V must therefore be permanently applied to the input. If you want to shut down the operating system, you must apply 24 V to the PC-ON input. Once the operating system has shut down, the PC power supply unit sets the Power Status output from 24 V to 0 V. This indicates that the shutdown is complete. You can then switch off the power supply. If you remove the 24 V from the PC-ON input before you have switched off the power supply, the operating system restarts. Therefore, 24 V must be applied to the input until you have switched off the power supply.
Besides the main switch of the machine, you can also install an additional ON/OFF switch to turn the machine on and off. The main switch can thus remain switched on in principle and thus ensures that the PC is still supplied with power during the shutdown of the operating system. Via the Power Status output, you can switch, for example, a contactor that switches off the entire system. The load capacity of the Power Status output is limited to max. 0.5 A. No fuse protection is required.
You can use the UPS output to supply another device, such as a control panel as an operating element. If the power supply fails without a UPS, both the industrial PC and devices supplied via the UPS output are switched off directly.
Switching on and off with 24 V power supply unit with UPS
If you have ordered your industrial PC with a 24 V power supply unit with integrated UPS instead of a 100-240 V power supply unit, the industrial PC has a power supply socket (X101) and a socket for external wiring (X102). You can connect an external battery pack to the industrial PC via the voltage socket. The socket for external wiring contains an input PC-ON and an output Power Status.
You can use the PC-ON input of the PC to control the startup and shutdown of the operating system. The PC-ON signal is inverted, which is why the operating system boots up at 0 V at the input and shuts down at 24 V. During operation, 0 V must therefore be permanently applied to the input.

Driver installation
When you switch on the device for the first time, the optionally pre-installed operating system will be started. For any additional hardware you have connected, you have to install the drivers yourself afterwards. In addition, the Beckhoff Device Manager starts automatically. The Device Manager is a software from Beckhoff that supports you in configuring the device.
If you have ordered the device without an operating system, you must install this and the driver software for the additional hardware you have connected and for the components inside the device. Please follow the instructions in the documentation for the operating system and the additional components.
UPS software components
The UPS software components with the corresponding drivers must be installed on the PC in order to operate the power supply unit as a UPS. The software components and drivers are already installed on delivery of the PC with operating system. If they are not, you have to install the installation package Beckhoff UPS yourself.
You can obtain the installation package from Beckhoff Service (service@beckhoff.com). You then use the installation package to install the UPS software components. The UPS software components come with a detailed help function. Call up the help files either directly from the configuration register by clicking the Help button or start the file under Start > Programs > Beckhoff > UPS software components.
