Firmware/BIOS description

Parameterize your device in the BIOS Setup. 
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. 
 
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.
