Modbus addresses assigned to firmware modules, features, settings, and corresponding
data items (i.e. default values, min/max values, data type, and item size) may change
slightly from version to version of the firmware. Addresses are rearranged when new
features are added or existing features are enhanced or modified
Upgrading the software
The latest EnerVista software and firmware can be downloaded from:
https://www.gegridsolutions.com/app/ViewFiles.aspx?prod=mm200&type=7
After upgrading, check the version number under Help > About. If the new version does
not display, try uninstalling the software and reinstalling the new versions.
Uninstalling files and clearing data
The unit can be decommissioned by turning off the power to the unit and disconnecting
the wires to it. Files can be cleared after uninstalling the EnerVista software or MM200
device, for example to comply with data security regulations.On the computer, settings
files can be identified by the .m30 extension.
To clear the current settings file do the following:
1. Create a default settings file.
2. Write the default settings file to the relay.
3. Delete all other files with the .m30 extension.
4. Delete any other data files, which can be in standard formats, such as COMTRADE or
.csv.
You cannot directly erase the flash memory, but all records and settings in that memory
can be deleted. Do this using these commands:

• CLEAR LAST TRIP DATA PROMPT
