C2, C3, E2, E4, TB2, TB3, TB4 are not reported as default. Values can still be read via RAWRW if required. Alternatively, if dedicated CAN messages for
those additional accumulators are needed, they can be enabled within the DC2732A_CAN.ino source code via the preprocessor definition ENABLE_CAN_
ID_ACC_C2_TO_TB4. Those messages will have the CAN IDs 0x128–0x12E.
Notes:
1. “T, [Bytes], Bits’ indicates the type, byte order (typically big-endian) and number of bits. For example, “Int, [0:2], 24” refers to a 24-bit big-endian integer
value stored in CAN message data bytes 0 to 2 where byte 0 is the MSB.
2. CFG2949 flag refers to the Boolean signal within CFG2949 that enables the related measurement signal. Above CAN messages will be send if any of the
related CFG2949 flags are enabled. Signals within CAN messages that are not enabled will report the most negative value.
