SP Name | Operator Presence and Awareness Status Checksum |
SP Description | The operator presence and awareness status checksum is the CRC checksum of the first 56 data bits of the operator status message using the CRC-8-CCIT Polynomial (0x07/0xE0/0x83). This CRC is used to verify that transmitted data was not corrupted prior to transmission over the CAN bus. An operator status message which fails a checksum test shall be treated as indicating an operator status sequence error. This means that if an operator status message is received which fails the checksum test, the receiving device shall treat the operator status presence and awareness states as if value 2 ("error indicator") is received. If the operator status PGN recipient has detected and entered the operator status sequence error state due to failed checksum test, it shall listen for 8 correct, sequential operator status messages in a row before returning to operator status sequence operational state. |
