Exports the Controller Application File (.caf) file that currently resides in each field controller under the field bus. For example, if 10 controllers are defined under the field bus, 10 individual .caf files are exported. Each .caf file contains all the logic components needed to represent a system. You can save the exported .caf files to any location on your computer. The name of each .caf file matches what is defined in the File Name field on the Resource screen. This command is only available when a field controller under an engine is selected in the All Items tree.
