  1. Measurement problem

    I can also say that Keyence is good at sending a representative to the facility to look the application over and figure out the best solution to a problem. What TWS linked is a better solution then what I posted.   Mike  
  2. Measurement problem

    Maybe look into something like this?   https://www.keyence.com/products/sensor/positioning/ix/  
  3. In my experience, the inspection system had to give an explicit flag to tell the part was good. I used to work in a CD/DVD manufacturing facility and every disc was inspected. Sometimes the handling arm was out of alignment so when it placed a disc on the inspection spindle, it would use vacuum to hold it and rotate it to inspect it. If the disc bounced on the spindle it wouldn't get a vacuum confirmation and the inspection cycle did not run. There would be no outputs of results, so the handling system assumed it bad. The inspection system had discrete outputs to flag a disc good, and several outputs for bad discs depending on what kind of defect it saw. This way a graph can be shown on screen tracking what kind of defects it is seeing so adjustments to the process can be made to increase the yield.   Mike  
  4. What is your favorite and least favorite HMI software?

      Looks interesting, but for the model train project I want to stick with the HMI panel. My eventual plan is once I am "done" writing the programs for train operations I will transfer the PLC setup to my around the wall layout in my living room. I have a free standing pedestal which used to be a take out robot from an injection molding machine. The original HMI is an old Proface. It will be replaced with the C-More HMI I am currently using. The button box I am using for the project will simply be eliminated and wired to this stand.  Most of the parts used for this project were scavenged from old CD/DVD replication lines that were being scrapped. I have on hand a lot of the Proface HMI's but the cost for the software was too much, so I decided to use a C-More. I probably should put those panels up for sale on Ebay or something, someone could probably use them.   Mike  
  5. What is your favorite and least favorite HMI software?

    Where I work they use a lot of AutomationDirect's Cmore HMI panels. Recently for the EA9 series they made the software free to use. I found it easy to learn and they have a lot of video tutorials to view. I am using a C-More micro panel (least expensive option) for my model train project. It has less features, but for what I need for my train project, it works. The project will also determine what HMI would suit best depending on the features needed for the project.   Mike  
  6. EA3 Micro Panel

    I don't think the EA3 panels have a built in clock, the EA9 series does.  The suggestion above if the PLC has a clock would work fine. Mike  
  7. Can anyone guide me on how to choose a PLC?

    With seeing the amount of I/O points on the old controller, a Micrologix 1100 could be a replacement, You can use the free version of RsLogix Micro starter lite to program it.  Mike  
  8. Good Quality Affordable HMI & SCADA

    Some Cmore Micro panels support the PLC you want to use via serial port. https://www.automationdirect.com/adc/shopping/catalog/hmi_(human_machine_interface)/c-more_micro_panels The EA3 series the software is free. I have two of these and they were not that expensive. Mike  
  9. cONTROLLING A BIPOLAR STEPPER MOTOR WITH MICROLOGIX 1400

    I saw the different versions. For what I need it is 5 volts to 24 volts. The LED indicator from the remote switch glows either green or red depending on the track switch position. (basically the wire is either +/- 5volts) and I want to pick that signal and make it an input to the PLC so it knows the switch is in position and not jammed. (if switch is not in either position, the wire will be zero volts)   Mike

    Thank you for posting this link, I have been having an issue with my Model train project interface and this board will solve the problem! Thank You! Mike
  11. Advice on choosing a PLC for a project

    I have a Linksys router on my home network with WPA2 password protection. The wifi can also be protected by MAC addresses (not allow wifi access if the MAC address is not specified as OK) I have a NAS on the network which is why I have it locked down, critical data on my computers is automatically backed up to the NAS drive. All computers and such are hard wired ethernet.
  12. Advice on choosing a PLC for a project

    I have the Cmore HMI communicating with the Micrologix 1400 with Ethernet now. So that was a good learning tool to setup the computer, PLC, and HMI to use Ethernet instead of serial communications. The screen shown is from the "First generation" (The Micrologix 1000) so the tag database is based on the old inputs and outputs. I togged those outputs to verify that the HMI does see the tags, as shown here, I toggled the switch positions so you can see the green and red arrow, and I toggled the old track power outputs which show on the HMI as white squares. This was enough to prove communications are working properly between the PLC and the HMI. The screens will have to be completely re-written for the new PLC of course, but I am pleased with my progress, as it was a good learning tool to set up ethernet. I do like that I can have both RSlogix and Cmore software open at the same time and no more swapping serial cables. Perhaps in the future it could be possible to put it on my home network if there is a reason to do so. I did set it up with IP addresses of 192.168.2.XX where my home network uses the typical 192.168.1.XX addresses so there would not be an IP conflict. Mike  
  13. Advice on choosing a PLC for a project

    I missed that, thanks for pointing that out, I can stick a end bracket between the switch and the PLC to open a gap between them, I do have some room left on that DIN rail, I just have to slide everything over to the right a bit. Mike  
  14. Advice on choosing a PLC for a project

    Analog is new to me so I didn't realize that, so when I change to decimal view it will show me how it would be addressed. Thanks you.  
  15. Advice on choosing a PLC for a project

    At the time I took the screenshot. it was to show how it is displaying the analog I/O. For testing, I do go to run mode and go online to be able to toggle the outputs on and off to check my wiring and I have started to test the inputs. Once I have verified my wiring, I will clean it up and zip tie it. I have those sticky pads under the wires to mount them. Next I will create a blank project file and fill in the symbol and descriptions of the I/O (IE: I:0/0 is Emegency Stop, I:0/1 is Automatic mode) Mike
