Solution
The
FactoryTalk Historian ME
 module display is not responding.
  • Check to see that both the module and the chassis have power and that the LED display is
    on
    .
  • Check the Ethernet cable port. Be sure that the Ethernet display LED lights are lit normally and that the messages scrolling on the display are OK.
The time displayed on the web client is wrong, even if the clock time has already been synchronized in manual mode.
The battery may need to be replaced. The battery is non-rechargeable and field-replaceable. For information on replacing the battery, see the
FactoryTalk Historian Machine Edition Module Installation Instructions (Publication 1756-IN106
).
The four-character LED display stops scrolling.
  • Check to see if the data server has stopped functioning. Go to the
    Web Diagnostics Firmware
     tab, and check the Data Server page. If the data server has stopped functioning, restart the module.
  • Check to see if the CIP application has crashed. If so, go to the
    Web Diagnostics Firmware
     tab, and check the CIP page for errors. If there are any, click
    Restart
    .
The Ethernet port lights are not illuminated.
  • Contact your IT department to verify that your system is properly connected to your network.
  • For details on the Ethernet cable, see "Wire the Ethernet connector".
The module's CPU is experiencing continuous high usage (90-100%).
Go to the
Web Diagnostics Hardware
 tab, and check the CPU and RAM page to find out each service's usage and determine which processes are the most CPU-intensive.
The FactoryTalk Historian ME module cannot obtain an IP address from a DHCP server.
  • Ensure that the network cables are properly connected and that the module is properly connected to the network.
  • Contact your IT department to verify that a DHCP server is running on the same network as the module.
  • Ensure that the port LEDs on the module are lit. If so, restart the module.
  • If the port LEDs are not lit, the module may require service by Rockwell Technical Support.
The MAC address scrolls across the display.
  • The Ethernet port has failed to acquire an IP address.
  • Restart the module.
The ME module is online but you cannot access it through its host name.
The FactoryTalk Historian ME module hostname may have a "_" in its name. According to Microsoft DNS server naming standards, this prevents the module from being recognized by its host name. To solve this problem, the underscore "_" must be removed from the module's name.
For details on naming the ME module, see Change the module name.
For details on DNS naming standards, see the Microsoft TechNet site and search for "DNS naming standards".
