General annotations
- Data might be not available during ignition off
- Physical Layer according to ISO 11898 (250kb/s)
- Application Layer according SAE J1939/ 71
- Data Link Layer according SAE J1939/ 21
- If there is a discrepancy between definitions in this document and the SAE, the SAE documents are valid only.
- Mentioned reference no. in this document is referring to SAE document
- The priority/source address of each partner is different and has to be masked by connected FMS-ECU.
- In the FMS-ECU a switchable terminating resistor is recommended.
- If the information is delivered the function/data has to be delivered according FMS-standard definition.
- If the information is not available the function/data has to be sent as not available according to SAE
- “not used for FMS-standard” means that there might be data sent according SAE but are not used in FMS-standard interface. If no information is sent, then it has to be sent as “not available”.
- “reserved for FMS-standard” means that as long as there is no definition it is sent “FF (not available)”
