Back up a copy of the in-service settings for each commissioned MM200 device, so as to
revert to the commissioned settings after inadvertent, unauthorized, or temporary setting
changes are made, after the settings defaulted due to firmware upgrade, or when the
device has to be replaced. This section describes how to backup settings to a file and how
to use that file to restore the settings to the original relay or to a replacement relay.
Setpoints must be saved to a file on the local PC before performing any firmware
upgrades. Saving Setpoints is also highly recommended before making any Setpoint
changes or creating new Setpoint files.
The Setpoint files in the EnerVista MM300/MM200 Setup window are accessed in the Files
Window. Use the following procedure to download and save Setpoint files to a local PC.
1.
Ensure that the site and corresponding device(s) have been properly defined and
configured as shown in Connecting EnerVista MM300/MM200 Setup to the Relay,
above.
2.
Select the desired device from the site list.
3.
Select the Online > Read Device Settings from Device menu item (at the top of the
page), or right-click on the device and select Read Device Settings to obtain settings
information from the device.
4.
After a few seconds of data retrieval, the software will request the name and
destination path of the setpoint file. The corresponding file extension will be
automatically assigned. Press Receive to complete the process. A new entry will be
added to the tree, in the File pane, showing path and file name for the setpoint file.
An error message will occur when attempting to download a setpoint file with a
revision number that does not match the relay firmware. If the firmware has been
upgraded since saving the setpoint file, see Upgrading Setpoint Files to a New Revision,
above, for instructions on changing the revision number of a setpoint file.
The following procedure illustrates how to load setpoints from a file. Before loading a
setpoints file, it must first be added to the EnerVista MM300/MM200 Setup environment as
described in the section, Adding Setpoints Files to the Environment.
1.
Select the previously saved setpoints file from the File pane of the software main
window.
2.
Select the Offline > Edit Settings File Properties menu item and verify that the
corresponding file is fully compatible with the hardware and firmware version of the
target relay. If the versions are not identical, see Upgrading Setpoint Files to a New
Revision, above, for details on changing the setpoints file version.
3.
Right-click on the selected file and select the Write Settings File to Device item.
4.
Select the target relay from the list of devices shown and click Send. If there is an
incompatibility, an "Incompatible Device" error message will occur:
