Preconditions¶

The CODESYS J1939 Safety library implies preconditions to provide the required safety level.

The CAN-mini-driver used with CAN-low-level (used in J1939SafetyStd.CL2Driver) has to provide a timestamp for receive messages (later referred to as “capture timestamp”). This is necessary to ensure receive order detection for Safety Header Message / Safety Data Message (SHM / SDM) pairs.
