Watlow F4T User Manual

Watlow F4T Controller • 34 • Chapter 2 Configuration Using Composer
First, a couple of fields (parameters) within Setup must be addressed, identified in the red
boxes below.
Log to - must be set to internal memory to automatically move the files to the shared folder.
File Size Limit - defines the maximum file size that will be moved to the shared drive.
Second, based on the example entries made above, the File Transfer fields need to be filled
in accordingly.
After these screens have been populated as shown, data logged files, once they reach approx-
imately 1MB in size, will be moved from internal memory to the shared folder (SambaStore).
Configuring a Trivial File Transfer Protocol (TFTP) Server
In order to use the TFTP file transfer option, a TFTP server must be setup and running on
your computer to service the TFTP transfers from the F4T. The user will need to specify the
IP address of the remote computer, and also the remote computer name.
TFTP requires no authentication and can transfer a file as large as 20MB to a remote host
computer. There are many TFTP servers available and many can be downloaded off the in-
ternet free of charge. To enable a TFTP transfer, within Composer or via the UI, simply enter
the IP address for the remote computer and ensure the TFTP server is running on the remote
computer.
