What is a B2P file?

B2P files mostly belong to TwinCAT. B2P files are used as a hardware package within the Beckhoff TwinCAT PLC program. They store configuration data that defines how industrial hardware modules are set up and managed.

The file follows the internal format known as FtcPck.FtcXml.HwPackage.

It acts as a container for settings needed by the TwinCAT system.

It is tailored for use with Beckhoff’s automation technology.
