the Ethernet interface can process them.
†
Bad local application request; discarded request
Check for valid COMMREQ command code.
†
Bad remote application request; discarded request Try to validate the operation of the remote node.
†
Cannot locate remote node; discarded request
Error reported when message received where IP address cannot

Message from PLC for unknown Ethernet interface task. Check
COMMREQ function block.
Comm_req – Wait mode not allowed
Check COMMREQ to make sure sent in no-wait mode.
LAN data memory exhausted – check parms; resuming
The Ethernet interface does not have free memory to process
communications.
†
LAN I/F capacity exceeded; discarded request 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.
LAN system-software fault; aborted connection
resuming
Internal system error.
†
LAN system-software fault; restarted LAN IF
LAN system-software fault; resuming
Module software corrupted; requesting reload Catastrophic internal system error. Contact GE Automation – NA.
