The Camera is an SR1000 from Keyence and the Laser is an MD-X1000 from Keyence also. Its a Fiber Laser Marker.

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!

Very nice! Sounds like it is exactly what I need to understand background workers. I'll take your word, I just sent you a PM.

I am a little bit leery with the door switch, since it concern with safety aspect.

Not sure what you mean exactly, but the door is completely interlocked with a redundant safety relay circuit to the laser marker. The Laser will instantly stop and all output power is removed as well as a physical shutter moves into place in the path of the beam. It's very safe. As if that wasn't enough, we actually engage a mechanical lock on the door anytime the Laser output is on. The customer can't even open the door while it's performing it's function.
