Switching the Industrial PC on and off
The Industrial PC does not have its own mains switch. Instead, the wiring for starting up and shutting down
the PC is connected via input PC_ON. You can connect a simple push switch to the PC_ON input and use it
as a standard power switch. This allows you to position the switch as desired and make it easily accessible.
The Power Status signal indicates whether the PC is switched on or off. Read this signal to find out when
you can switch off the main supply voltage.
First switching on and driver installation
NOTE
Public networks
Connecting the PC to public networks without additional protective measures can compromise the safety of
the device.
• Protect the PC before connecting it to public networks.
The Industrial PC is started when the system is switched on or when the power supply is connected.
When you switch on the Industrial PC for the first time, the pre-installed operating system (optional) 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 PC.
If you have ordered the PC without an operating system, you must install this and the driver software for the
additional hardware you have connected and for the devices in the PC yourself. Please follow the
instructions in the documentation for the operating system and the additional devices.
Switching off the Industrial PC
NOTE
Data loss due to running software
Switching off the Industrial PC before ending the running software and shutting down the device can lead to
data loss.
• Quit the running software and shut down the device before switching it off.
When the system is switched off or disconnected from its own power supply, the Industrial PC is also
switched off.
If 24 V are applied to the PC_ON input, the PC shuts down properly. The PC_ON signal is inverted, i.e. the
PC shuts down if the 24 V connection is live.
Once the PC has shut down, the Power Status output is switched from 24 V to 0 V. This output can be used,
for example, to switch a contactor that disconnects the entire system from the power supply. The maximum
load for the Power Status output is 0.5 A and a suitable fuse should be provided.
You can assign different access rights to all users in the operating system and in the application software.
Since there is a risk of data loss if the Industrial PC is switched off incorrectly, assign the rights advisedly. A
user who is not allowed to terminate the software should not be allowed to switch off the Industrial PC.
