Read the data queue entry with function HReadSeek.
HReadSeek(DTAQ_FIFO,TIMEOUT, "000000")
When TIMEOUT key field is 0, the system returns immediately the value, or set HOut to True is the data queue is empty.
Set TIMEOUT key value to a number of seconds to wait before to exit with HOut = True.
Example:
WaitStrg is string
WaitStrg = timeout
HReadSeek(DTAQ_FIFO,TIMEOUT, WaitStrg)
IF HOut = True THEN
Info("DataQueue is empty !")
ELSE
// Value is here
data_lue=DTAQ_FIFO.DATA
END
