You can provide either the NAME or an ID (ID parameter as an input) of a pre-existing data
log. If you provide both parameters and a valid ID does correspond to the NAME data log,
then the ID is used, and the NAME ignored.
The NAME must be the name of a data log created by the DataLogCreate instruction. If only
the NAME is provided and the NAME specifies a valid data log, then the corresponding ID
will be returned (ID parameter as an output).
Note
General usage of data log files
• Data log files are automatically opened after the DataLogCreate and DataLogNewFile
operations.
• Data log files are automatically closed after a PLC run to stop transition or a PLC power
cycle.
• A Data log file must be open before a new DataLogWrite operation is possible.
• A maximum of eight data log files may be open at one time. More than eight data log files
may exist, but some of them must be closed so no more than eight are open.
