User Action
Message from PLC for unknown Ethernet Interface task. Check COMMREQ
function block.
Check COMMREQ to make sure sent in no-wait mode.
Error in configuration. Verify that IP address, Subnetwork Mask, and default
Gateway IP address are correct.
Underlying communications software detects error transferring data;
resuming. If persistent error,
check connection to LAN and operation of remote node.
HW fault, perform a power cycle. If problem persists, contact Technical
Support.
Internal system error. If problem persists, contact Technical Support.
Internal system error. If problem persists, contact Technical Support.
The Ethernet Interface does not have free memory to process
communications. If problem persists, contact Technical Support.
A frame was received in which the source MAC Address was the same as
this station's MAC Address. All stations on a network must have a unique
MAC address. Immediately isolate the offending station; it may be
necessary to turn it off or disconnect it from the network. This station
remains Online unless you intervene to take it Offline.
Internal system error. If problem persists, contact Technical Support.
Verify that connection limits are not being exceeded.
Replace the Ethernet Interface.
Excessive backlog of transmission requests due to excessive traffic on the
network. For a sustained period the MAC was unable to send frames as
quickly as requested. If problem persists, contact Technical Support.
External condition prevented transmission of frame in specified time. Could
be busy network or network problem. Check transceiver to make sure it is
securely attached to the network.
Internal system error. If problem persists, contact Technical Support.
Internal system error. If problem persists, contact Technical Support.
Internal system error. If problem persists, contact Technical Support.
Transceiver or transceiver cable failed or became disconnected. Reattach
the cable or replace the transceiver cable. Check SQE test switch if present
on transceiver.
Internal error. Check that the Ethernet Interface is online. If problem
persists, contact Technical Support.
Internal error accessing non-volatile device. If problem persists, contact
Technical Support. Replace the Ethernet Interface.
Catastrophic internal system error. Contact Technical Support.
