Workflow

The following describes the workflow for programming a KONNEKTING device. The diagrams show the required actions the programming device (f.i. KONNEKTING Suite) needs to do in order to program a KONNEKTING device.

Start Programming Mode

Before the programming can start, the KONNEKTING device needs to be in "programming mode" (short: ProgMode). The following diagram describes the two possible ways to achive ProgMode.

drawio: Protocol0x01WorkflowProgMode

Do Programming

After ProgMode has been achived, it's time to do the actual device programming.

drawio: Protocol0x01WorkflowTables

The parts for "Program CommObjects" and "Program Parameters" are optional an depend on what the user want to program. So you can skip or include them, as you like.

Working with files

This is about working with files, means transfering files to the device, including firmware upgrade

todo ...

Device Memory Layout

The device's memory is divided in multiple sections:
