Issue Details

The error occurs when I try to read data from ECU using DAQ List mode with ECUMC Toolkit 15.0 on Veristand, it works fine in LabVIEW example though. How can I solve this problem?

Solution

There is a high probability that the error is related to the SET_S_STATUS command. When using DAQ List mode, there is an optional command, SET_S_STATUS. It means some ECU need SET_S_STATUS command and others not. On Veristand's custom device, there is an optional entry, which allows users to select the output of SET_S_STATUS command. However, even if you select the output option, ECUMC Toolkit 15.0 does not output SET_S_STATUS command on Veristand's custom device. This is an internal error of ECUMC Toolkit. So if your ECU needs SET_S_STATUS command using DAQ List mode, the communication will not proceed normally.

Additional Information

Fortunately, the above error is fixed in ECUMC Toolkit 18.5. So you can communicate using DAQ List mode with an ECU that requires the SET_S_STATUS command. The download link is below.
