The ID parameter is an IN/OUT type. First you indicate the ID value of the existing data log
whose structure you want to copy. After the "DataLogNewFile" instruction has been

the ID reference. The required detection DONE bit = TRUE is not shown. An example for the
logic of the DONE bit can be found in networks 1, 2 and 4.
