Creating a boot project

The following memory resources are available for generating the boot project

approx. 250 kbyte flash on the Bus Terminal controllers of the BX series;
approx. 48 kbyte flash on the Bus Terminal controllers of the BCxx50 series.

PLC Control

After logging into TwinCAT PLC Control, a boot project can be created.

Opening a PLC project
Selecting the target system (or selection the serial interface)
Logging into the BX/BCxx50
Creating a boot project (Online\Create boot project)

The PLC LED lights up green once a valid boot project is available on the BX/BCxx50.

In the Bus Terminal controllers of the BX series, the PLC LED flashes orange while boot project is created. The PLC LED lights up orange if no boot project is available on the BX.

Deleting a boot project

The boot project can be deleted from the Bus Terminal Controller. The following steps must be followed:

Opening the project
Logging into the Bus Terminal Controller
Deleting the boot project (Online\Delete boot project)

The PLC LED lights up orange when the boot project is deleted.

	Using the current project as boot project After an online change the old project is still shown as boot project. To use the current project (after the online change) as the boot project, the boot project has to be recreated.

Bypassing the start of the boot project*

With the Bus Terminal controllers of the BX series, starting of the boot project during booting can be prevented by pressing the Navi button. This does not delete the boot project. The project is reloaded when the Bus Terminal Controller is rebooted.
