File trigger

The File Trigger executes a transfer if a file gets changed or created.

After double-clicking on the transfer object, set the following properties:

Path	Select the path to observe.
Fallback scan interval	The OPC Router gets notifications if files get changed or being created. If it misses a notification, it will observe the directory additionally in this interval.
Filename pattern	Define a filename pattern. You can use placeholders like *.
Read binary	Select this option if you want to read a binary file like *.doc, *.jpg, * .xlsx, ...
Read Text, Encoding	Select if you want to read a simple text file and select the files encoding.

Target options

Delete after successful transfer	Deletes the file which triggered the trigger after a successful transfer.
Success destination	Moves the file which triggered the trigger in a special folder
Prepend UTC Timestamp to filename	Activate if you want to prepend the UTC timestamp to the file. For example the file “test.txt” gets renamed to “20191204_095646_test.txt”.
Delete after error transfer	Deletes the file which triggered the trigger if a transfer aborts for some reason
Error destination	Moves the file which triggered the trigger in a special folder if the transfer gets an error
Prepend UTC Timestamp to filename	Activate if you want to prepend the UTC timestamp to the file. For example the file “test.txt” gets renamed to “20191204_095646_test.txt”.
Number of retries	If the OPC Router can't access the selected file, it can retry for n times.
Seconds between tries	Select the time between the retries.
