Communication issues due to
blocked network ports
•
Blocked network ports on the computer running Daniel MeterLink or on a company
LAN can prevent connections to the meter or prevent certain features from
working. These issues may occur over Ethernet, Modem and Direct serial connec-
tions. Reference the list of network ports used by Daniel MeterLink in the Help file
and the symptoms of having blocked ports. Contact your IT department for
assistance in resolving these issues.
•
Error condition of a blocked network:
—
Cannot connect to a meter
—
Cannot collect Archive log files
—
Cannot view or stream waveforms in Waveform Viewer or Signal Analyzer.
—
Cannot upgrade firmware.
—
Communications lost over serial or modem connections while
Daniel MeterLink is idle on a screen.
•
Symptoms of blocked network:
—
If a PING is blocked on this network port, serial or modem connections could
be lost after approximately 15 seconds of inactivity. This issue can be
confirmed by checking the log_meter log file in the Temp data folder. The
path of the Temp data folder is shown in the Daniel MeterLink About dialog.
—
A blocked FTP port will generally not prevent a connection to the meter, but
will prevent log collections and program downloads. A blocked FTP port could
prevent a connection in the event the meter is running a newer version of
firmware for which Daniel MeterLink does not currently have a database con-
figuration file. If this is a case, a message stating “Error reading database
config file dbconfig<databaseversion>.xml from the meter.” will be displayed.
—
A blocked DB API port will report “Error 10001 opening database connection
to <IP address>”.
—
A blocked Streaming port will report an error message “Unable to open a
control socket”. This will occur when opening the Signal Analyzer window or
clicking Read or Stream to File in the Waveform Viewer.
