  1. Micrologix 1400 series C

    I just check mine. I have RSlogix Micro starter, version 12.00 and it does not list Micrologix 1400 C as an option. Did they recently release a C series? Last year when I was shopping for a PLC Only the A and B series was listed for the 1400. I chose the A series since I don't need the enhanced password capability for my train project. Mike  
  2. Standard Pumping Station Logic

    Could you post a PDF version of the file? Mike  
  3. 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  
  4. Measurement problem

    Maybe look into something like this?   https://www.keyence.com/products/sensor/positioning/ix/  
  5. 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  
  6. 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  
  7. 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  
  8. 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  
  9. 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  
  10. 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  
  11. 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
  13. 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.
  14. Awhile back I posted about my project which I am doing to learn how to program PLC's I took an unusual approach and built a model railroad layout using parts I scavenged from machines that were being scrapped. The PLC I am using now is a Micrologix 1000 and RSlogix Micro starter lite (free software) I have been posting my progress here. https://www.nepaview.com/model-train-plc-project.html I have learned enough so far that I was able to design and build a fire suppression system for plastic sheetlines. In this case I used a Click PLC since I did not need a lot of I/O and the project is only 14 rungs of code, although I will be building on it to add more features. I had originally planned the project with a Micro 810 PLC so I downloaded the CCW software and installed it to test it out and to get used to it before I started the project. CCW gave me problems right from the start with library errors and such. I uninstalled and re-installed and it made a mess of the laptop. I then installed the software on a different computer and was getting errors (some different) but again, the software was useless. That is when I decided to change the PLC to a Click. That software ran flawless, but it is not as user friendly as RSlogix and it does not support simulation, which is a key item I want moving forward with my train project. Back In June I attended a Rockwell Automation On Tour event which was very interesting with lab and demo units set up. There was stuff there that would be applied for work projects such as some of the newer drives they have, and they also had a Micro series PLC setup as a demo. However, they even admitted that demo unit wasn't working well, and yes it was because of CCW. I did get to talk about my project with one of the engineers there and the place that held the event is a reseller and they told me they can sell to an end-user which is good. He also had some ideas for me as far as how I was coding to improve my skills and how to solve some issues I am having with the project.   I want to replace the Micrologix 1000 with something better. Aside from the fact that this PLC is obsolete and I have already had to fix it twice for output problems (replace relays) The amount of I/O is fixed and it does not support any analog I/O. With my experience with the Click PLC, I discount that already because the software is cumbersome and does not support simulation. I did eventually get the demo unit with CCW to work and had some time to write some test code, but from my understanding, the free version does not support simulation, only the developer version. Researching online, a Micro 830 with a few add on modules would give me what I need. Another option is to go with a Micrologix 1200, The RSlogix for that PLC is not free, but not expensive either and it is an environment I am used to with the starter lite version. Another option I am considering is an Automation Direct Do-More BRX PLC. The software I downloaded already and plan to kick the tires on some test code and it supports simulation, but maybe its just because I am used to RSLogix, so far it seems a bit cumbersome to use. I requested quotes from the distributor,  to go with the Micro830 series would cost about $1,300, but if I go with CCW Developer, I would probably have to put it in a virtual machine since the software seems so finicky, and I have read other peoples posts about the software which makes me question going this route. The Micrologix 1200 option is a bit more, $2,000 but in my experience with RSLogix Micro Starter Lite, its bulletproof and has never caused me any headaches. I would assume the Starter Lite version ($155 ) would be the same, just able to support the 1200 - 1500 series PLC's   Thoughts?   Mike  
  15. 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  
  16. 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  
  17. 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.  
  18. 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
  19. Advice on choosing a PLC for a project

    I got as far as powering up and getting a heartbeat on the PLC. I am new to using Ethernet for a PLC but with some work I got communications up and running between the computer, PLC, and the HMI panel. What I found odd is going online, the PLC didn't seem to recognize the additional modules and I couldn't add them or auto-detect. Went offline and added them in manually, then I defined some of my elements I wanted (say 50 B3 values, 200 timers, etc...) wrote that back to the PLC and then it showed up. Now RSlogix shows the modules and they appear to be ok, I togged one output on slot 3 and the output did come on the module. I had to connect the button box to the unit since it is the safety circuit (emergency stop with reset button) This way I can start toggling the outputs to make sure the relays close for the track switches and power. The safety circuit will drop the 24 volt control voltage and de-energize all outputs if the emergency stop circuit opens. One thing that seems weird is looking at the screenshot of RSlogix, it shows the analog input as I:0.4 ? not IV0 ?? Same with the output.   Mike  
  20. Advice on choosing a PLC for a project

    I have been posting pictures and some videos on my website, located here:   https://www.nepaview.com/model-train-plc-project.html These videos shows the HMI screens: https://youtu.be/PCPA4QjvoE0 https://youtu.be/vrGwERqydGI I started a new page with my "Second Generation" build with the Micrologix 1400. I do plan on improvements to the HMI screens. The way I was doing the alarms was not the best way and when I hit a wall with my programming and asked for help here and another fourm, I have a better approach in mind. Of course this means re-writing most of my code but that is fine since I am learning. I purchased RSlogix Micro Starter and installed it so its ready to go once I power up and connect to the PLC. The "chatter" i describe in the second video I will be writing debounce code to eliminate it. Mike  
  21. Advice on choosing a PLC for a project

    I have been working on the new build of the project when I can find time. The wiring will be cleaned up once I can power it up and test it to make sure everything is good. I added the ethernet module to my Cmore HMI. Next step will be to re-do the track layout as a lot electrically will be different.   Mike  
  22. Advice on choosing a PLC for a project

      It was not mentioned in the thread, but that will no doubt be an advantage to this PLC. I purchased the Micrologix 1400 and three I/O modules. The parts arrived yesterday. I am still awaiting them to setup the rockwell online user id so I can download the RSlogix Micro Starter.  There is no doubt some things I have to learn about the new PLC before I even resume my programming. I still have to make an order with Automationdirect for parts. (terminal blocks and such) it turns out the HMI panel I have can do Ethernet with a $50 add in module which I plan to purchase as well as a small din Rail Ethernet switch. This will provide a better connection between the PLC and the Cmore HMI and I should be able to program either of them without unplugging and plugging in USB or serial ports. I am also going to buy a wire marking label maker as there will be more wiring involved and I need to keep track of it. Of course the next step is I have to tear down what I built and re-do it with the new PLC and additional I/O I now have available.  Problem now is I work a goofy 12 hr shift so spare time is more limited to work on this project I have been looking over the suggestions posted above and I think I have a better plan in mind for writing the routines in a better way. One good thing is this PLC has more memory so some limitations I had with the Micrologix 1000 won't apply now. More variable data to work with (bit values, timers, etc) and I can have more ladder routines.  When I wrote the last working routine (The main and side interchange program) I noticed in the printed report, the memory was over 60% filled which told me I would not have the memory space for all the routines I had planned to write. This was a deciding factor to make the investment to upgrade. Although I am using this as a learning tool, in the end this project will be used to control my around the wall layout that I have in my living room. SO there is an end result of my efforts.   Mike    
  23. Advice on choosing a PLC for a project

    My local Rockwell dealer was able to process the order with a credit card since I am purchasing as an end-user. I decided on the Micrologix 1400. I also purchased the RSlogix Micro starter since it is software I am already familiar with (the free lite edition) I have worked with this software quite a bit and have found it to be rock solid. The train transformer takes a 0 - 3.3VDC input on the wiper for throttle. I think it would be a better choice to build a voltage divider so the full 10VDC output from the ML1400 will give a 3.3VDC output maximum. This would prevent over driving the transformer input in the event the analog output goes too high. This way 100% (10V) would be 100% throttle. I can also use one of the analog inputs to sense the transformer output. This will require rectifiers and also a voltage divider. This can help me sense a derailment. If the transformer detects an overload or a short, it shuts down. This will be no problem as I have done electronics since I was a kid. The ML1400 has ethernet built in and I can buy a module to add ethernet to my Cmore panel. I do have one of those small 24VDC switches that was scavenged from a panel that was scrapped. I can make my own cables as they should just be standard ethernet cables. So as far as the computer goes, all I need is say a USB to ethernet to interface to the setup? I want to keep the built in ethernet port tied to my network and internet. Mike  
  24. Line Guide Sensor with BRX Analog Input

    According to the installation manual, this unit is connected to a controller that provides the +/- voltage supply. You need to look at the controller manual to see what kind of input or output it provides. Mike   Fife_SE-26B_Manual.pdf
  25. Advice on choosing a PLC for a project

    I also went back on AutomationDirects site and discovered I can get an Ethernet port for my current HMI panel for around $50 and add it on. The stand I have for the HMI is already cut out for the HMI panel so I don't have to modify it again.   Mike
