Hallo,

Now I try to realise UDS commands via ISO-TP (in the first step without FD) for this device:

WORD st = CANTP_Initialize(PCANTP_USBBUS1, PCANTP_BAUD_500K);
TPCANTPMsg request = {0};
request.SA = PUDS_ISO_15765_4_ADDR_TEST_EQUIPMENT;
request.TA_TYPE = PUDS_ADDRESSING_PHYSICAL;
request ...

I use the PCAN-UDS interface and I set in all messages:
SA=0xF1
TA=0
The resulting COB-ID is internal set to 0x18.0xDA.0x00(=TA).0xF1(=SA).
How I can change the front part to other values?

I'm using the PCAN-UDS.dll and the handle is initialised:
TPUDSCANHandle Channel;
TPUDSStatus status;
Channel = PUDS_USBBUS1;
status = UDS_Initialize(Channel, PUDS_BAUD_500K, 0, 0, 0);

For the requests the address infos are set in this kind:
NETADDRINFO->SA = PUDS_ISO_15765_4_ADDR_TEST ...
