Example for option string A typical option string may have the following structure:
/MAXFILES=20 /SCANTIME=5000 /FILENAME=test_?.txt /FILENAME=*.log
In this example, up to 20 files can be monitored. The default directory is scanned every
5 seconds following file modifications. Files with “log” or “txt” extensions are monitored.
Only modifications to “txt” files starting with the character string “test_” are detected. In
addition, all files with the extension “log” are monitored.
Example of a possible
error
The size of the modified file written to SIZE may not be correct. This may be the case, for
example, if a large file has been copied to the parameterization memory via FTP and the
FILE_NOTIFY block has been parameterized with a SCAN_TIME of 1 second. In this case,
the block immediately indicates that a new file has been created and provides information
about the current size of this file. Because the file is still being written, the size indicated
does not match the actual size of the file.
Table 3-10 Options for the option string
