Recommended action(s)
• Blocked network ports on the computer running 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 connections. Reference the list
of network ports used by 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
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 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 MeterLink does not currently have a database
configuration 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.
• Verify that the resistance of transducers is within Specification (2
Ω).
• Check the Acquisition Module.
• Check the interconnect cables between the Base assembly and the
Transmitter Electronics Enclosure.
