If you have a PAC controller that's remote and you're wanting to update the project on the SD card but don't have a PC there with Parker Automation Manager software, you can update the project:
From the programmer's PC with Parker Automation Manager software, under the Online menu, select Create Boot Application option. Then choose the destination folder to save the files. It should create two files, a .app file and a .crc file. Send these to the user, and using an SD card reader with the PAC SD card, replace the existing files with the new files in the Project folder.
