Caution
The order in which the components are upgraded is critical. Assuming
a system of a DGC-2020HD and expansion module(s) is in a state
where the DGC-2020HD is communicating with the system expansion
module(s), the expansion module must be upgraded before the
DGC-2020HD. This is necessary because the DGC-2020HD must be
able to communicate with the expansion module(s) before the DGC-
2020HD can send firmware to it. If the DGC-2020HD were upgraded
first, and the new firmware included a change to the expansion
module communication protocol, it is possible that the expansion
module(s) could no longer communicate with the upgraded DGC-
2020HD. Without communications between the DGC-2020HD and the
expansion module(s), upgrading the expansion module(s) is not
possible.
Note
If power is lost or communication is interrupted during file transfer to
the DGC-2020HD, the firmware upload will fail. The device will
continue to use the previous firmware. Once communication has been
restored, the user must start the firmware upload again. Select Upload
Device Files from the Communication pull-down menu and proceed
normally.
Upgrading Firmware in Expansion Modules
The following procedure is used to upgrade firmware in the expansion modules. This must be completed
before upgrading firmware in the DGC-2020HD. If no expansion module is present, proceed to Upgrading
Firmware in the DGC-2020HD.
1. Place the DGC-2020HD in OFF mode. This can be accomplished by clicking the Off button on the
Control screen inside the Metering Explorer or by pressing the Off button on the DGC-2020HD
front panel.
2. Enable the expansion module that is present in the system. If it has not already been enabled,
enable the expansion module on the Settings > System Parameters > Remote Module Setup
screen.
3. Verify that the DGC-2020HD and the associated expansion module are communicating. This can
be verified by examining the pre-alarm status using the Metering Explorer in BESTCOMSPlus or
from the front panel by navigating to Metering > Alarms. There should be no Loss of Comms pre-
alarms in the pre-alarm status when communications are functioning properly.
4. Connect to the DGC-2020HD through the USB or Ethernet port if not already connected.
5. Select Upload Device Files from the Communication pull-down menu.
6. You will be asked to save the current settings file. Select Yes or No.
7. When the Basler Electric Device Package Uploader screen (Figure 179) appears, click on the
Open button to browse for the device package you have received from Basler Electric. The
Package Files along with File Details are listed. Place a check in the boxes next to the individual
files you want to upload.
