Ethernet Communications
For public disclosure
13.5.3.1 PLC Fault Table Descriptions
Check that PLC CPU is running normally (usually in Run mode)
Check to make sure you are not sending COMMREQs faster than
the Ethernet interface can process them.
Check for valid COMMREQ command code.
Try to validate the operation of the remote node.
Error reported when message received where IP address cannot
be resolved. Error may indicate that remote host is not operational
on the network. Check that remote host is operational on network
and its addresses are correct.
Message from PLC for unknown Ethernet interface task. Check
COMMREQ function block.
Check COMMREQ to make sure sent in no-wait mode.
The Ethernet interface does not have free memory to process
communications.
Verify that connection limits are not being exceeded.
Ethernet interface is not properly connected to the network. Check
the connection to the network hub or switch.
Internal system error.
Catastrophic internal system error. Contact GE Automation – NA.
COMMREQ received when Ethernet interface cannot process
COMMREQ. Make sure Ethernet interface is configured and online.
Attempt has been made to configure a feature not supported by the
Ethernet interface. Check CPU revision; order upgrade kit for CPU
and/or Ethernet interface.

13.5.4 Checking the Status of the Ethernet Interface

The application program can monitor the status of the Ethernet interface using the status
bits described below. The beginning address of the data is the Status Address entered
when configuring the CPU. Refer to chapter 6, the section,
Interface for details.
