Thanks. :) If you can ping the camera, I would expect everything else to work. I'm a little surprised ping is working if your laptop adaptor is on a different subnet, though. Cognex's software will be able to find the camera regardless of the subnet, but that's not the same as a ping, and it only has enough functionality to set the camera IP address (and name, if memory serves). After you set the camera's IP address, your laptop adaptor needs to be on the same subnet as the camera to do the rest of your work. When I'm connected to a machine network, I usually dedicate one network adaptor to that (Ethernet) and use another adaptor (Wifi) to stay connected with office/internet networks.

@@breen-machine Hi, thanks for the reply. I understood, in my case the cameras are in a dedicate network such as 192.168.1.x , my laptop is connected to the Wifi (different subnet), I have created internal routes to one subnet be reachable to the cameras subnet, but it didnt work yet. I believe because of the Insight application is broadcasting only for the same network. I thought there would be such an option to enter manually with IP address. It seems a limitation of the Insight Explorer application. If you heard there's a newer version, let me (us) know pls. Thanks a lot again.

@@breen-machine Hey. I found how to do. Unfortunately it's not possible to upload pictures here, however at In- Sight Sensors, do an opposite click , go to Remote Subnets. Just needed to add the new ip address from the subnet, application is going to discover and found the devices properly. Tks!

That's great to hear. Thanks for the feedback! :)

Great question. Most PLC inputs have some debounce filtering built-in, so it's rarely an issue. I can't think of a time in the last 10 years I've had to debounce in logic. That said, if you do find a case that needs debounce in the code, you'd have to do that one at a time for each input using timers.

Hi, the first go-to for reflectivity issues is usually a polarized filter. Machine vision usually does best with diffuse reflection of light. The shininess you're talking about is a specular reflection. Specular reflection maintains polarization while diffuse does not. So a polarized filter on the light source at 0 deg and another on the camera at 90 deg will mostly remove the shiny reflections from the image. Good luck!

Sorry for the slow reply. This video is available on our website. courses.breen-machine.com/courses/virtual-machines

I'm glad you enjoyed it! :) Thanks for the feedback. I'll try to get some more videos up soon.

@ 🙏🏼

I'm not sure what you mean. A one shot, by definition, stays on for one scan of the program. Ever part of the program will see the bit high exactly once before it goes low again. If you're talking about the pushbutton one shots (ie PassPB_OS), only one branch of the rung is active at a time, depending on the state of the one shot. That's how we want it to work.

Sorry for my slow response. :) The easiest and most reliable way to measure width is to setup the image so it can see both edges you're measuring between. If that's not possible, the camera will need to be able to infer something about the other edge. For example, if the other edge is always against a fixed guide, you know where it is. In that case, take a picture of a max size part and min size part, measure the edge location in pixels, then interpolate between those values to get an actual measurement. The interpolation will be linear (y = mx + b) and can be done in the camera or the controller (PLC, PC, or whatever is receiving the measurement). I usually trigger from the controller or based on a sensor that tells the system when the part is in place. If that's not convenient for the 1 photo per second requirement, you can also setup a trigger event in the spreadsheet using the Timer function.

Thanks for the feedback! :) It keeps me motivated to make more.

Thanks for watching! I think this is a little more than I can get into through RUclips comments. The first thing to do is always check the manual. If that doesn't get you what you're looking for, I like to reach out to the supplier (wherever you bought the PLC and servo) because they usually have technical resources that are more personable than the manufacturer. If that doesn't work, then call the manufacturer tech support. And of course, if you'd like help from a friendly integrator, contact info is on our website: www.breen-machine.com/contact-us/ Good luck!

Excellent point, and well stated. Thanks!

I haven't tried connecting a camera to a C-More before. Usually, I see Cognex cameras being connected to Cognex Vision View displays or another web capable device.

It's a fair question, and I think I'd be asking it in your shoes. In my experience, most people in industry trying to do basic PLC programming (maintenance, tech school students, even controls engineers) don't have a compsci background. These videos are for them. It's been on my list for a while to make a quickstart PLC programming tutorial for compsci people... whenever I get some time. :)

Not true

Haha, I trust you. People on the internet are always very honest about the things they hate. ;) What do you prefer?

Changing the JOB on practically every Cognex camera takes a very long time (up to 10 seconds). The profinet communication frame itself is exceptionally complex and consists of numerous conditions. The cameras from the IS2800 series are a complete misunderstanding altogether. The software freezes, is not well-developed, and Cognex panels were not compatible (and probably still aren't). I definitely prefer using Keyence products (IV, IV2, IV3, and IX cameras depending on the needs). Due to all these issues with Cognex, I have developed an aversion :) @@breen-machine

Hi @rickrodriguez2477. Unfortunately, I don't have distribution rights for PCIS.exe, so I can't give it to you. You may be able to get it from your local Rockwell distributor. If there's something else I can do to help, let me know: www.breen-machine.com/contact-us/

The 2800 series is new and uses Vision Suite. I don't think it'll work with Explorer

Yes, most industrial cameras are designed for robot applications, and Cognex is a common choice. If you want to connect the camera directly to the robot, check with the robot manufacturer. They usually have one or two brands they work with. Otherwise, you can use a PLC as an intermediary. In this case, you'd send the results of an inspection to the PLC, then the PLC would load the appropriate registers in the robot, probably all over Ethernet.
