Eventº12º TCP events (Continued)

Possible Cause and Resolution

18ªConnection to remote node failed; resumingº

Sent RST in tcpacked( ). Entry 3 is the endpoint (TCP connection identifier). Entry 4 is the TCP state as shown above. Entry 5 is the code field of the offendingpacket.

19ªConnection to remote node failed; resumingº

Sent a TCP RST to a remote node aborting a failed TCP connection. This abort was done due to a mismatch in local and remote connection status. Entry 3 is the endpoint (TCP connection identifier). Entry 4 is the TCP state:

1 = CLOSED

2 = LISTEN

3 = SYN-SENT

4 = SYN-RECEIVED

5 = ESTABLISHED

6 = FIN-WAIT-1

7 = FIN-WAIT-2

8 = CLOSE-WAIT

9 = LAST-ACK

10 = CLOSING

11 = TIME-WAIT

Entry 5 contains TCP flags.

1a ªConnection to remote node failed; resumingº

Sent a TCP RST to a remote node aborting its TCP connection. This abort was done because the connection was unknown to the local Interface. Entry 3 is the source TCP port. Entry 4 is the destination TCP port. Entry 5 is the code field of the offending TCP packet.

1b ªConnection to remote node failed; resumingº

Gave up on TCP connection establishment due to exceeding the limit on the listen queue size.

1c ªConnection to remote node failed; resumingº

Closed a connection that has not yet been set up Entry 3 contains the end- point, and Entry 4 contains the TCP state. This exception may serve to explain a subsequent event 12, Entry 2 = 1a exception.

ff(Not reported to PLC Fault Table)

An error has occurred while retrieving program task names, but the software is unable to clear an entry in the PSM transfer table. Entry 3 is the returned status code and is significant to developers.
