I emailed you screen shots of the tasks running on the IPC. However I think I discovered what the issue was. I had a section of code for writing to a CSV file in a certain instance and Excel was not present on that machine yet, I think it was bogging down the AHMI solution. After installing Excel, and running the AHMI on the BEckhoff IPC, there is no more delay.
Hello, I leave the link with the siemens driver using snap7, in front of any doubt I will try to help as much as I can since I am not an expert in .net programming, I do what I can. I have tested it with snap7's own simulator and with an S7-1500 PLC. (sorry my english is translated)

Hi,
I realize this is several years old now, but I was wondering if the stand-alone driver was ever ported to .NET core? I'm looking for exactly this: a .NET core Rockwell driver.
Nice work! I've seen those ADAM modules long time before, but always wondered how they work with no real time OS like windows. Are you polling data from it, of so at what rate? Do you use a background worker for this?
Asking because this is something I want to learn to do (multi thread and background workers), there are many applications I could use it.
AHMI has helped me a lot with its already made controls that does not require to write code for these, but now I was looking for do it myself in other drivers like for Siemens.
So from my main thread I call an initialization Function and check to make sure the Adam module , Camera and Laser can be reached by Ethernet. From each check I start a background worker thread for each device where I continuously loop untill the main thread closes the worker threads.
I'm polling the Adam module at 25ms interval and the Keyence at 100ms. I created a class for an input device which contains name, port, bit, state etc and I loop through and check/set all the inputs on the Adam. Then I write to the Outputs in a similar fashion.
I also have a Auto Process thread which uses the input values and can also set the output states for the I/O conditionally. I'd be happy to give you the code if you want. It can use some improvement but it's a start.
Thanks everyone for your compliments!
Ok, thanks for the response. My rs232 port is currently being used to go to an AB 1761-Net-ENI DF1 to Ethernet/IP converter for data acquisition. May be a silly question but is it possible to put a switch in right after that and go back through the converter EthernetIP to rs232 for the Advanced HMI?
Not a silly question. I did something similar, but depending on the amount of connetions you use on the Ethernet side (the Net-ENI has a very limited amount of input connection, I think they are only two), you may be able to do it. If you type the Net-ENI IP address in your web browser you will be able to see some data like the actual connections to have a idea. Or you can just try with a sample app that reads a variable from your PLC, and see what happens.
There is another option I ended using, another interface like the Net-ENI but from a third party RTA Automation

It has a larger amount of connections available, and has some other useful features not present in AB's. Downside, is that did not work well with an Ingear communication driver we tried to use with. It did not work with AHMI at the beginning but as usual Archie responded with a great support and made changes that fixed it. I think he added the patch to main beta.
Anyway, I think using the Ethernet connection will be the correct route for you.
I only need 1 more connection really for the AHMI communication. At that point would the EthernetIP for SLC driver work, or would I need to use something else?
Could an RS232/DF1 cable splitter be used at the PLC? One side goes out to the ENI, one is dedicated to the AHMI?
I tried that with no luck. I've matched the IP to the ENI, and I get a "Write Failed!No response from PLC during write" error.
