Basler Electric DGC-2020 - Manual (Page 204)

The language of the front panel LCD can be changed by uploading a different language module into the
DGC-2020. The DGC-2020 stores the language module in nonvolatile flash memory; the language
module contains all language translations for the DGC-2020. The language module can be
reprogrammed through the communications port. In general, any time a firmware upgrade is made to the
DGC-2020, the language module should be uploaded as well.
The DGC-2020 can be used in conjunction with several expansion modules that expand the DGC-2020
capabilities. DGC-2020 expansion modules include LSM-2020, CEM-2020, and AEM-2020. When
upgrading the firmware in any component of this system, the firmware in ALL of the components of the
system should be upgraded to ensure compatibility of communications between the various components.
CAUTION
The order in which the components are upgraded is critical. Assuming a
system of a DGC-2020 and expansion modules is in a state where the DGC-
2020 is communicating with all of the system expansion modules, the
expansion modules must be upgraded before the DGC-2020. This is
required because the DGC-2020 must be able to communicate to the
expansion module before the DGC-2020 can send firmware to it. If the DGC-
2020 were upgraded first, and the new firmware included a change in the
DGC-2020 to expansion module communication protocol, it is possible that the
expansion modules could no longer communicate with the upgraded DGC-
2020. Without communications between the DGC-2020 and the expansion
modules, upgrading the expansion modules is not possible.
NOTE
If power is lost or communication is interrupted during file transfer to the DGC-
2020, the DGC-2020 will cease operating and will not recover automatically. If
this occurs or if the front panel HMI becomes blank and all LEDs are flashing
at a 2-second rate, the DGC-2020 will not have valid firmware installed and the
firmware must be uploaded again. To accomplish this, cycle power to the
DGC-2020 and activate the DGC-2020 plugin in BESTCOMSPlus. 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 DGC-2020 expansion modules. This must be
completed before upgrading firmware in the DGC-2020. If no expansion modules are present, proceed to
Upgrading Firmware in the DGC-2020.
1. Place the DGC-2020 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-2020 front
panel.
2. Enable the expansion modules that are present in the system. If they have not already been enabled,
enable the expansion modules on the SETTINGS > SYSTEM PARAMETERS > REMOTE MODULE
SETUP screen.
3. Verify that the DGC-2020 and all associated expansion modules 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-STATUS > PRE-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-2020 through the USB port if not already connected. Firmware upgrades cannot
be accomplished through the Ethernet port, with the exception of the LSM-2020.
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 4-78) appears, click on the Open
button to browse for the device package you have received from Basler Electric. The Package Files
