ModbusTCP Not Connecting

[ruscito]

I am attempting to get the Modbus Driver to connect to a MicroLogix 1400. The MicroLogix is configured for ModbusTCP on its ethernet port. Polling with Modscan is successful with the RemoteTCP connection type. I have also captured the data in Wireshark while polling with Modscan.

When I start the Modbus driver in WinCCOA I get these two errors:

WCCOAmod (1), 2018.09.26 10:39:45.114, IMPL, WARNING, 54, Unexpected state, ModMasterConnection, connectReady, Error during connectReady for 139.209.29.177 on port 502
WCCOAmod (1), 2018.09.26 10:39:47.120, SYS, SEVERE, 54, Unexpected state, ModMasterConnection, sendRequest, Timeout expires for connection to server 139.209.29.177 on port 502

When I capture the packets with Wireshark there is nothing leaving the network interface at all. Absolutely no WinCCOA traffic of any kind is leaving my NIC. It is like the driver isn't even trying to connect.

Anyone know what I am missing?

I don't know how to attach two configuration screenshots.

Thanks,
