Specifies the sampling rate for this frame on the AFDX bus in milliseconds. This means a
repetition rate the data shall be sent cyclic. Specify value starting with 1msec in multiples of
1msec. Refer also to parameter ul_Bag of function
FdxCmdTxCreateVL
or
FdxCmdTxCreateHiResVL
which restrict usage of sampling rate.
Note:
This parameter is only applicable for a sampling port.
Example:
VL-Load:
VL-Bag * (
1
Sampling Rate UDP Port 1 +
1
Sampling Rate UDP Port 2 + ... )
1
If above calculated value is bigger than 1 VL is overloaded and sampling rates can not
be achieved.
Queuing ports are additional load to the VL and are only transmitted if bandwidth is not
fully exhausted by sampling ports.
Output:
AiUInt32 *pul_UdpHandle
Handle to the UDP port.
Return Value
Returns FDX_OK on success or a negative error code on error.
Error Codes: FDX_ERR
