BIOS description

Overview
Parameterize your device in the BIOS Setup.
BIOS Setup program
The BIOS Setup program, or BIOS Setup for short, is located, together with the setup
parameters, in a FLASH block on the motherboard.
Change the setup parameters of the device in the BIOS Setup, e.g. system time or boot
sequence.
Changing the device configuration
Your device configuration is preset for operating with the included software. You should only
change the default setup parameters if technical modifications to your device require
different parameters.
NOTICE
Malfunctions can occur with running software CPU
If a BIOS update of the PC is performed while SIMATIC software controller, a SIMATIC WinAC
for example, is running, the software CPU can malfunction, resulting in communication
interruptions or failures, for example. Other actions that put a heavy load on the PC
hardware, for example, running hardware tests such as benchmarks, can result in
malfunctions of the software CPU.
Do not run a BIOS update or other actions that would put a heavy load on the hardware
during operation of a software CPU.
Switch the software CPU to "STOP" before you run a BIOS update or perform other critical
actions.
Note
Documentation
BIOS Setup is described for all devices and device configurations. Some BIOS submenus or
