On the MVI56E platform configuration files get stored to the CompactFlash card. This way if the module fails the CompactFlash card can be placed in a replacement unit without the need for downloading a configuration to the module.
Note: On the MVI56E-MCM and the MVI56E-GSC the configuration is stored in ladder logic and transferred to the module on start-up. This also enables a replacement module to installed without downloading a configuration file.
