■ Format
short CITL_WaitCollectDataRecvEvent (unsigned short usWaitRecord, unsigned long ulTimeout)
■ Argument

■ Description

function, this function ends normally without waiting for data to be sampled. Acquire the target data in the temporary area
and execute the function again. When data sampling in each sequence scan is stopped, an error occurs.
• The specified timeout value is rounded to the tick unit. Specify a timeout value of one tick or more.
