Watlow Series PD - Manual (Page 142)

TFTP Server Configuration
There are a number of TFTP servers available on
the web. Search the web on the keywords TFTP server.
• The TFTP server should preferably be located on
the same subnet as the Series PD.
• The TFTP Server should also be configured to write
all files to a predetermined folder.
• Some TFTP server configurations allow only a se-
lect range or specific IP addresses to access the server.
This may be set to accept files from any number of Se-
ries PD. Each file will be uniquely identified by the
Series PD name and file start date and time in this
directory.
• It is advisable to configure the TFTP server to reject du-
plicate inbound files. When the Series PD is restart-
ed, it will attempt to write all files in the file system
to the TFTP server. There is no reason to backup the
files that already exist on the TFTP server.
• The TFTP server does not need to be configured for out-
put files.
• The TFTP server should be configured to start automat-
ically any time the computer is rebooted.
TFTP Server IP Resolution
Get Server IP from Server Name
Using the Server name entered in the TFTP Server
Name: field, the unit will attempt to resolve the server
name through the DNS (Domain Name Server) to ob-
tain the correct IP address. This form is useful in case
the IP address of the TFTP server should ever change.
Fixed Server Address
The Series PD will use the IP address in the TFTP
Fixed Server Address: field to locate the server.
Send Email On File Transfer Error
Yes
Enable the control to generate the following email
message if a file transfer error occurs:
Device name: PD000311
The datalogging TFTP server IP was unable to be
resolved or the file system is full.
This message is generated because:
1. The Series PD cannot transfer the files to the TFTP
server for some reason.
2. The Series PD is configured to stop logging when the
file system is full.
No
Disable sending an email for logging errors.
Delete All Datalog Files
This command button will delete all inactive log
files. If logging is currently enabled the active log file
will not be deleted from the File System.
Datalogging: Clock
The Clock time is generated by an internal Real
Time Clock (RTC) and is used only for the optional dat-
alogging capability.
The RTC does not support automatic Daylight Sav-
ings Time change over. This must be handled manually
where required.
Clock Time:
Current Time
Allows entering the current Time using a 12 hour
format, AM/PM
An additional text field is supplied that allows enter-
ing the local time zone format such as CDT for Central
Daylight Time or PST for Pacific Standard Time. This
field is written into each Log file to identify the time
zone that the file was originated from.
NOTE: In order to maintain clock accuracy when changing parame-
ters on the Clock page, make sure the last change is to update the
clock. This will prevent inadvertently submitting a change with a
time that is several seconds old.
Current Date
Allows entering the current Date as the Day, Month
and Year.
Synchronization
Time Synchronization allows the real time clock to
be synchronized with an external time server and
recheck it every 15 minutes. This provides better than a
1 second accuracy for the log files.
Synchronize Clock With Time Server:
Yes
Enable the Series PD to synchronize with a time
server.
No
Do not use time server synchronization.
Time Server IP Resolution:
Get Server from DHCP
Many network configurations support time servers
to maintain the correct time for all computers on the
network. This option allows the unit to read the time
server IP address from the DHCP server. The Series PD
may display the time in UTC (Universal Standard
Time, or GMT).
