Technical request for lifetime of flashROM (MC4N)
The VRs are saved in a file system like a flash-stick so it is not erasing the flash every time you change a value. It uses many pages of flash. The expected lifetime is published on the Trio website on the specifiations pages.

MC_CONFIG vs Flash parameters
All Motion Coordinators store the IP_ADDRESS, IP_NETMASK and IP_GATEWAY in Flash memory. So there is usually no need to add them to the MC_CONFIG. There are some differences with other system parameters. MC4N-ECAT, MC4N-RTX, MC6N-ECAT, Flex-6 Nano ...
