The Boot Code is the startup code for the device. The Boot Code acts like a mini-operating system in the device and supports the communications necessary to transfer the Main Code to the device.
By default, the Radio Codetransfer option is available for Wireless Field Bus Routers and repeaters. This option speeds up the process of upgrading the code in Wireless Field Bus Routers. Refer to the Wireless Field Bus Routers product documentation for guidelines on transferring to wireless devices.
If the Radio Code and Main Code are both selected for transfer, they will be sent together. The Radio Code transfer option is required to upgrade a Wireless Field Bus Router that is used as a repeater, and when the Wireless Field Bus Router version is at a different version from the boot and Main Code versions of a controller.
The switch communication mode option switches communication protocols in an MS/TP or N2 controller compatibility with the FC bus.
The SA Bus Firmware Code option sends a file to update devices on the SA Bus of the device. With this feature, you can update multiple Point Expansion Modules at a time. The tool sends the required data to the device so that the device can update SA Bus devices defined in the Application.
The Application Code tells the device the actual code/sequence and priorities of the control strategy created in the tool (for example, definitions of the Inputs, Outputs, Control Logic, and Network variables).
