Accessing a dll with an array as argument in Teststand

[Tonnie]

Hello

I have made a dll with the following function call :

int __declspec(dllexport) __stdcall FSCOM_ModbusQuery (int nComport, unsigned char ucAddress, unsigned char ucFunctionCode, unsigned char ucTxData[], int nTxDataLength, unsigned char ucRxData[], int nRxDataLength)

I want to access this function call in Teststand 2010 SP1. I have made 2 array's in Teststand and gave the adresses to the function call (as you can see in "Capture.png" and "Capture1.png" ).

When i try to run the sequence I get an error on the   ucTxData and ucRxData  with message "Expected number, found array of numbers".

How can i solve this problem

Thanks in advance

What are you specifying as the data type for the array parameters? You probably do not have them specified as arrays.

Hello

I have made 2 number array's in teststand. Is it not possible to make 2 unsigned char array's ?

I think you misunderstood what I meant. In the Module specification tab of the panel you can change the data type that the function expects. You likely have it set to the wrong thing. It should be set to an array of numbers where the elements are 8-bit unsigned integers.
