Relay State

This parameter contains the status (active state) of all the BMS outputs and inputs. The format is as follows:

Bit #0 (0x01): Discharge relay enabled
Bit #1 (0x02): Charge relay enabled
Bit #2 (0x04): Charger safety enabled
Bit #3 (0x08): Malfunction indicator active (DTC status)
Bit #4 (0x10): Multi-Purpose Input signal status
Bit #5 (0x20): Always-on signal status
Bit #6 (0x40): Is-Ready signal status
Bit #7 (0x80): Is-Charging signal status

Bit #8 (0x0100): Multi-Purpose Input #2 signal status
Bit #9 (0x0200): Multi-Purpose Input #3 signal status
Bit #10 (0x0400): RESERVED
Bit #11 (0x0800): Multi-Purpose Output #2 signal status
Bit #12 (0x1000): Multi-Purpose Output #3 signal status
Bit #13 (0x2000): Multi-Purpose Output #4 signal status
Bit #14 (0x4000): Multi-Purpose Enable signal status
Bit #15 (0x8000): Multi-Purpose Output #1 signal status

For all of these values, a "1' signifies that the signal or relay in question is enabled or active (high). A "0' indicates that it is inactive or off (low).
