Check to make sure that the logic application is not sending
COMMREQs faster than the Ethernet interface can process them.
Reduce the rate at which the application is sending COMMREQs
to the Ethernet interface. If problem persists, contact Technical
Support.
Check to make sure that the logic application is not sending
COMMREQs faster than the Ethernet interface can process them.
Reduce the rate at which the application is sending COMMREQs
to the Ethernet interface. If problem persists, contact Technical
Support.
Check for valid COMMREQ command code. If problem persists,
contact Technical Support.
Try to validate the operation of the remote node. If problem
persists, contact Technical Support.
Error reported when message received where IP/MAC 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 controller 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.
Contact Technical Support.
