public static extern int receiveByteDA100(int daqda100, byte[]
byteData, int maxData, out int lenData);
Parameters
daqda100 Specify the device descriptor.
byteData Specify the field where the received byte data is to be stored.
maxData Specify the byte size of the received data.
lenData Specify the destination where the byte size of the actual data
received is returned.
Description
Stores the received data to the field specified by the parameter up to the specified
byte size.
• Returns the byte size of the actual data received if the return destination is
specified.
• If multiple bytes of data exist, repeat the function.
• Do not perform communications using other functions until the data retrieval is
completed. Other functions may not operate properly.
• The user must carry out determination of the data end.
• Used for recieving binary output when implementing a model-specific talker
