Internal: DINT

Description

This command stores all of the RMC controller data to Flash memory for storage in case of power loss. The RMC will continue to control motion as usual during a Flash update. On the RMC75/150, the green CPU LED will flash while a Flash update is in progress. For RMC75/150's with firmware prior to 3.30.0, if power is lost during a Flash update, all the data in the RMC may be lost.

Note:
You must Update Flash in order to save controller data, or it will be lost when or power is removed from the RMC!

Updating Flash from RMCTools

You can update Flash directly from RMCTools without using this command. See the Updating Flash topic for details. You may also be prompted to save to Flash when the controller is warm restarted after changing certain controller data.

Special Note

The Flash memory chips on the RMC75S, RMC75P, and RMC200 are limited 100,000 update cycles. The RMC75E and RMC150E are limited to 1 million update cycles. Due to these limits, you should take care to program the RMC so that this limit will not be exceeded during the life of the controller.
