Victron energy Color Control GX - DGN 60928 Unique Identity Numbers; RV-C in; Device Classes

20.1.3. DGN 60928 Unique Identity Numbers
The GX device will assign an individual Unique Identity Number to each virtual device. Change it only when using multiple GX
devices in one RV-C network.
The Unique Identity Number is used for the GX internal CAN-bus device "database" to compare devices during address
determination. To avoid clashes on CAN-Bus you must set the second GX device to the unique identity range of 1000-1499.
This can be done by setting the unique identity selector to 2 (2 * 500). This works exactly the same as for VE.Can, see the PGN
60928 NAME Unique Identity Numbers [95] section.
20.1.4. RV-C in
Tanks
Tested with Garnet SeeLeveL II 709 and tanks from the RV-C out function of another GX device.
Batteries
Lithionics is the only supported RV-C battery (including DVCC support).
20.1.5. Device Classes
This section provides a basic overview of how each device class will participate in the RV-C specification. In any case, "Level 1"
integration is largely supported (basic operation), with case-by-case enhancements.
AC standalone Chargers
• The AC-based charger class reports its operational status and configuration status using the CHARGER_xx group of RV-C
messages. User control must include basic on/off switching via RV-C as well as adjusting shore (AC) power limits.
AC standalone Inverters
• This class of AC inverters reports its operational status using the INVERTER_xx group of RV-C reports. Incoming command is
limited to on/off (enable/disable) via RV-C.
AC Charger / Inverter
• Combined inverter/charger - reports both CHARGER_xx and INVERTER_xx messages.
Solar Controllers
• Solar chargers will report their operational status in real time.
SOC Meters
• SOC meters can be used to report current battery health via RV-C: voltage, current, temperature, SOC, etc. RV-C requires that
only ONE device speaks for a given battery at a time, so if a proper BMS is installed, that will be the data source.
BMS (Victron, or Victron 3rd party supported)
• In many cases, the battery(s) in the system will be directly attached to a Victron Cerbo GX or Cerbo-S GX, either via Victron
equipment or via supported 3rd party compatible BMSs. Such batteries should be represented into the RV-C environment via
the DC_SOURCE_STATUSxx messages.
Tank Level meters
• Tank meters will be translated into RV-C messages, carrying forward the existing tank ID/ VRM Instance numbers.
