Watlow F4T User Manual

Watlow F4T Controller • 29 • Chapter 2 Configuration Using Composer
Note:
Due to wear-leveling operations of flash memory devices (internal - F4T and exter-
nal - USB), there may be some gaps within the data logged file.
Note:
If logged file is sent to USB, the *.csv and the *.enc file are written directly to
USB constantly. If the File Size Limit is set to 10MB or larger, the csv will continue
to be written continuously while the encrypted portion (*.enc) is chunked into
7.5MB files, buffered internally and then written out as 7.5MB chunks. If the maxi-
mum file size is set to 10MB, there will be two *.enc files for each csv (7.5MB and
2.5MB). If File Size Limit is set to 15MB, there would be two 7.5MB *.enc files for
each *.csv file.
- Log Interval: defines the frequency in which the log will be written, 0.1 second to 60
minutes.
- File Type: Encrypted (filename.enc), comma separated values (filename.csv) or Both.
- File Size Limit: 20MB maximum when using internal memory, 1GB when using USB.
- Memory Full Action: when selected log to device is full, Overwrite or Stop.
Note:
Logging to USB allows for Stop only, when memory is full.
- Date Format: MM/DD/YYYY or DD/MM/YYYY.
Note:
Applies to each individual log entry alone, does not apply to filename.
- Time Format: 12 or 24 hour clock.
Note:
Applies to each individual log entry alone, does not apply to filename.
5. Click on the File Transfer button.
- Auto Transfer Type: None, TFTP, Samba or USB.
Note:
When automatic file transfer is enabled, the file as it's being created, will be buff-
ered in internal memory. The file will be moved to its destination when it either
reaches the maximum file size setting or the user stops data logging. If automatic
transfer fails for any reason, data logging will continue and the files will be stored
in internal memory until internal memory fills up. The setting for Memory Full Ac-
tion (Overwrite or Stop) will then be implemented.
Note:
A user can initiate a file transfer manually at any time if one or more of the avail-
able destinations (USB, TFTP or Samba) have been configured.
- Samba User Name: Windows user account name with access to shared directory.
Note:
If using Asian fonts, you may need to create a Latin character set login for use with
Samba transfers.
- Samba Password: Windows user account password.
