• To update firmware on the controller or on a serial communication module on the
controller's rack. The card provides a convenient way to update firmware on
non-networked controllers. It's also useful if PAC Manager is not available to update
firmware.
• To temporarily boot the controller from firmware on the microSD card rather than from
the firmware in the controller, for example to test new firmware.
• To update, run, or test new PAC Control strategies if the controller is not on the
network, if PAC Control isn't available, or if you want to test a new strategy without
erasing the existing one.
The following table summarizes how to use the card; see the page in the last column for
