Thanks, i'll try out wireshark if I get a chance.

The getTagList has been running for just under an hour now and has not returned anything. There are a lot of tags but it shouldn't be taking this long.

The PLC connection event never fires.

What would I be looking for in wireshark?

I get that it comes from the PLC, but I am able to read the same exact tag in the AdvancedHMI program. What is different between my code and the AdvancedHMI? Is there some configuration that I'm missing?

The getTagList always either times out or if I set the max timeout value to something really high it hangs and never completes.

Support Questions / Read Failed. Path Destination Unknown, Status Code=5

As the title suggests, I keep getting the exception error "Read Failed. Path Destination Unknown,  Status Code=5" when attempting to read a tag from my PLC. The code is simple:

Code: [Select]

            var tagName = "inpHeartbeatRTA_Chroma19020_Bay4";
            var EIP = new EthernetIPforCLXCom();
            EIP.BeginInit();
            EIP.ComError += EIP_ComError;
            EIP.ConnectionEstablished += EIP_ConnectionEstablished;
            EIP.IPAddress = "192.168.129.2";
            EIP.EndInit();
           
            EIP.Read(tagName);
The weird thing is that I can read the same tag if I use the AdvancedHMI project by adding a comms driver and a control. After looking online for a few hours it appears Status Code 5 is usually the tag does not exist on the controller but I know this tag 100% exists. I'm out of ideas for debugging this issue, any help would be appreciated. Thanks!
