sc_gpi[n].rising_edge_triggered
▪
When set to 1, the input value will be populated to the destination upon detection of a rising
edge
sc_gpi[n].falling_edge_triggered
▪
When set to 1, the input value will be populated to the destination upon detection of a falling
edge
If the General Purpose Digital Input is configured as neither rising nor falling edge triggered, the input
value is continuously populated into the destination address. The configuration settings for the most
common functions are illustrated in the table below.

For advanced applications, General Purpose Digital Input may be configured to drive any Boolean
register within the BMS.

7.8. Protocol Settings

The Low-Voltage BMS supports the following interfaces for connection with external systems:
▪
10/100 Ethernet for Modbus TCP and Operator Interface connectivity
▪

CAN Bus

▪
RS485 for Modbus RTU
7.8.1. CAN Bus
Nuvation Energy BMS uses a flexible CAN reporting implementation which maps BMS registers to CAN
message identifiers.
Refer to Section 8.2 for more information on using this interface.
Up to 64 individual registers may be configured for periodic reporting by the BMS. Additionally, 4
configurable bulk report blocks are available for reporting repeating blocks of registers such as cell
voltage and temperature.
The basic CAN configuration can be done with the components and registers described below.
sc_canbus.enabled
▪
A flag which enables the CAN bus interface
▪
Set to 1 to enable CAN reporting
