5. TPS-1 boot subsystem
During each startup of the TPS-1, the firmware and the configuration are read from the boot Flash. The configuration contains also the MAC addresses
for the network ports which connect the device to other PROFINET IO devices.
5.1. Hardware Structure for the Boot Operation
The TPS-1 uses a boot loader which reads all necessary data from the boot Flash and carries out the necessary settings. The boot loader is integrated
into the ASIC and cannot be changed.

During the manufacturing process, the following data have to be written to the boot Flash:
• manufacturer information
• device data, device configuration
• I&M information
• operating mode of the TPS-1
• MAC addresses
• PROFINET CPU firmware (Target Host Image)
The necessary data for the boot Flash is assembled by the configuration tool TPS Configurator.
