Winco DGC-2020 - Manual (Page 138)

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.
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->SYSTEM SETTINGS
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 4-63) 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.
