BIOS update
With the SIMATIC IPC DiagBase software (included in scope of delivery of the CPU 1515SP PC2),
you can perform a BIOS update.
NOTICE
Irreparable damage to the BIOS
If the BIOS update is not performed correctly, the BIOS can be irreparably damaged so that the
device can no longer be operated and must be sent in for repair.
You may only start a BIOS update when it is absolutely necessary. The following applies here:
• Never interrupt the power supply during an update.
• The update process must be completed before you shut down the device.
• The BIOS update can only be performed in "Windows Only" mode.
• Do not perform a BIOS "downgrade".
Note
BIOS update with running Software Controller
If a BIOS update is performed while the Software Controller is running, the DiagBase
BiosManager issues the following error message: Error loading the BIOS file.
