Hi Archie,
I am using the drivers only in my C# project, the new version 3.99t is throwing Timeout Exception for all EthernetIPCLXCom methods (GetTagList(), Read()). The previous version (V3.99r) which we were using works just fine.

Hi Archie,

If you use the default VB project, add a BasicLabel to the form and set PLCAddressValue, does it work?

[uthaman]

Yes, I tried that, it works, but If am using the driver class EthernetIPCLXCom in a simple main program, its timing out.

[Archie]

Can you post the code you are using?

[uthaman]

Below is the code.


using System;
using AdvancedHMIDrivers;
using MfgControl.AdvancedHMI.Drivers;
namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            EthernetIPforCLXCom comobj = new EthernetIPforCLXCom();

            comobj.IPAddress = "X.X.X.X";
           

            MfgControl.AdvancedHMI.Drivers.CLXTag[] x = comobj.GetTagList();

            Console.WriteLine(comobj.Read("AFI"));

            foreach (CLXTag item in x)
            {
                Console.WriteLine(item.TagName);
            }
            Console.Read();
        }
     
    }
}

The default timeout is 15 seconds. Do you have a large number of tags? You can do a Wireshark capture to see if it is taking more than 15 seconds.

[Archie]

I created a patch that gives the ability to specify the timeout in seconds:

            x=ethernetIPforCLXCom1.GetTagList(30);


https://sourceforge.net/projects/advancedhmi/files/advancedhmi/3.5/Patches/

- Download and extract the driver patch 6
- Open your version 3.99t project in Visual Studio
- In Solution Explorer, expand down the AdvancedHMIDrivers project
- Right click the \support folder and select Add Existing Item
- Browse to and select the extracted patch file
- Rebuild the solution

Thanks Archie, this helps. I am facing a weird behavior, the old driver which is used to work with PLC A is not working now with the new driver.
The old driver which was not working with PLC B is working with new driver.
Both the PLC's are same model Allen Bradley Compact logix 5380.

[Archie]

If you could do a Wireshark capture of the one not working, I could tell from that what is the problem.

[uthaman]

I have attached the wireshark file, please take a look and let me know.

[Archie]

Are the PLCs both the same firmware? It's only returning Path Destination Unknown when it tries to read the tags. For some reason the Wireshark only recorded the responses and not the request.

[uthaman]

I am not sure about the firmware, I can check on that. I have attached the working PLC wireshark logs, in case you need.

On a side note, One of my team member is able to read the tags in the same PLC using a JAVA API (ethernet-ip https://github.com/EPICSTools/etherip), which is not working using the advancedHMI drivers. I double checked with him

[Archie]

This must be a firmware difference. The change in the AdvancedHMI driver could be 1 of 2 things. There was a change in connected/unconnected message and the new version requests less information about the tags.

[uthaman]

Not sure about the firmware here.

When I tried to read a tag value using Read(String tagName) in a main program using the driver, I am getting an error saying "Read Failed. Path Segment error (Invalid Tag name) status code=4",
but when I use the default VB project, add a BasicLabel to the form and set PLCAddressValue to the same PLC and read the same tag, it is displaying the correct tag value.

It is working with the VB form controls and not standalone.
