CCP Measurement

[Samoth]

Hello guys,

I use the NI PXI-8464 board conected through CCP prococol.( ECU M&C addon)

I have some problems , when I try to read different variables ( characteristic variables) from *a2l file. Below are 2 variables from my a2l file

First variable from a2l file;

/begin CHARACTERISTIC VariantCode ""
      VALUE 0x40001F3C __ULONG_S 0 VariantID 0 4294967295
      ECU_ADDRESS_EXTENSION 0x0
      EXTENDED_LIMITS 0 4294967295
      BIT_MASK 0xFFFFFFFF
      FORMAT "%.1"
      /begin IF_DATA ASAP1B_CCP
        DP_BLOB 0x0 0x40001F3C 4
      /end IF_DATA
      /begin IF_DATA CANAPE_EXT
        100
        LINK_MAP "VariantCode" 0x40001F3C 0x0 0 0x0 1 0x9F 0x0
        DISPLAY 0 0 4294967295
      /end IF_DATA
    /end CHARACTERISTIC

Second variable from a2l file

/begin CHARACTERISTIC Switch ""
      VALUE 0x40000C0D __UBYTE_S 0 NO_COMPU_METHOD 0 255
      ECU_ADDRESS_EXTENSION 0x0
      EXTENDED_LIMITS 0 255
      BIT_MASK 0xFF
      FORMAT "%.15"
      /begin IF_DATA ASAP1B_CCP
        DP_BLOB 0x0 0x40000C0D 1
      /end IF_DATA
      /begin IF_DATA CANAPE_EXT
        100
        LINK_MAP "Main__ITS_testSwitch" 0x40000C0D 0x0 0 0x0 1 0x87 0x0
        DISPLAY 0 0 255
      /end IF_DATA
    /end CHARACTERISTIC

I obtained the error (see attached) when I tried to read the second variable (Switch).

I think there is a problem with the conversion of each variable because ,long before ( obsolete a2l), I solved the problem just replacing NO_COMPU_METHOD with NO_FORMULA, but not in this case.

I attached 2 VIS;

CCP_Open.vi ( which opens the CCP communication);

CCP_ReadCharacteristic.vi ( which reads the value ).

And a shot with the error.

Thanks,

Hi Samoth,

I will look into this issue for you. Just a head's up that this issue is more related to the ECU Measurement and Calibration Toolkit than LabVIEW therefore better suited on the Embedded Networks Forum.
