  1. Storing to Non-volatile memory - sporadic error

    Thank you.  I reached out for a quote this morning.  Quite the tax, indeed!   I don't use PV'+s anyway, but I can use my SD cards for my current HMI's too.    Regards
  2. Hello, I am looking for some input.  I have a 1769-L18ER-BB1B in which I have a some projects that I am saving to SD cards.  I have saved a few already successfully, but when I went to save the latest sets, I keep getting an error that there is insufficient memory on the SD card when I select to store in Logix 5000.   I am using software version 32.011.  I have purchased 2GB Transcend SD cards and these have worked just fine before, but now I keep getting the error.  I verified the cards are empty and still formatted FAT16.  I have been using the same software revision and firmware revision for all programs.     Regards, Kris
  3. HMS Communicator network issue

    Oddly, shortly after I posted this, I decided to check the other PLC program, and indeed, the HMS communicator was also configured in that PLC as well with the same communication settings.  I am guessing the machine builder just reused and modified the same plc program for the 2nd fixture.  Next time I get to tha plant. I will be uploading an update with that device removed from the configuration.
  4. HMS Communicator network issue

    Hello,  We have a system a vendor built which utilizes a Compact Logix PLC and a peripheral piece of equipment tied in via use of an HMS communicator.  This system is also on the same network as 1 or 2 other plcs (depending what job is being run).  The 3 plcs share some handshaking signals via produced and consumed tags.  The system works just fine aside from 1 issue I don't seem to be able to resolve yet.   When we boot up the system with the HMS communicator, we are not getting any data back and forth between the PLC and the HMS communicator if either of the other 2 systems are plugged in at bootup.  Occasionally, even if the other 2 systems aren't hooked up, we also experience the same issue at bootup only.   This issue is easily rectified if we momentarily unplug the other PLC's physically.   Connection is immediately restored and works fine after.  I had looked at all settings I know to, but I don't see anything that could cause this.  I have set Unicast to disabled in the HMS device communication settings within Logix5000, thinking that it would help (which it has, as before we would often have the issue frequently when the machine was operating without the 2 additional systems hooked up).    Any ideas what I should be looking for?
  5. Rename tags in Siemens TIA Portal V13

    We had a computer failure in our facility and lost our latest backup from a project loaded in a machine.  I have an early backup, and I uploaded the program from the machine.  I would like to rename all the tags from the upload, as it is a bit older PLC so it didn't retain the names.  I figured I could open the db from the old program and just copy the tags and paste in the new program, or simply rename the tags in the new upload, but I am unable to.  Is there a trick? Do I have to be online with the PLC to do this? Or is it just not possible.  If i recall, it is an S7-300 (315-2 PN/DP).   I don't have access to the machine for some time, as I am working from home.  I thought this would be a good opportunity to fix the program.
  6. Part tracking - counting rejects

    I did very similar to what you suggested last thursday and it worked out well.  I got rid of the for loop and utilize an add instruction with a DINT, driven off a timer.  When the timer.dn bit is on, i increment the DINT 1(every 5ms).  I use this dint to look at which position in my tracking array to count.  I then add the value of the array position to a separate integer.  When my position integer hits 101 (I am only counting 0-100 using a limit test in the logic), I move the value accumulated to a new integer which is what I use in my logic for my alarm.  This all worked super well.  My initial struggle was counting the value in each part of the array.  I used indirect addressing to do it.     
  7. Part tracking - counting rejects

    Platform:  Logix5000 I have a relatively simple task I am trying to complete.  I need to track the status of a 100 part sequence to see how many parts have been rejected.  Essentially, I need to keep track of the last 100 cycles and count how many parts of the last 100 have been vision rejects.  I have written most of the logic, using FIFO with an integer with an array of size of 100.  Where I am getting stuck a bit is how to accurately get the count of the array.  I did make a for statement which will count the array and add it to a counter if the first bit is equal to 1, but this doesn't seem to be a clean way to do it, as I would also need to clear that counter before running the for statement.     Thanks,
  8. Click PLC and Keyence SR1000 barcode reader

    I was able to get this partially resolved yesterday afternoon.  So far I am able to send commands to the SR1000, and it is responding as expected.  Now I will work to get the data back, as that doesn't seem to be working yet.  
  9. Click PLC and Keyence SR1000 barcode reader

    That could potentially be the issue.  When setting up the send command, the click is quite a bit different than the AB.  There is a checkbox for the termination command however; there is the choice of 1 or two characters, and hex only.   I will give that a try next time I get out to the equipment.   They give you an option of choosing the term from a table.   didn't notice that the first time.   I'm more used to robots where you just type [CR].        
  10. Click PLC and Keyence SR1000 barcode reader

    Correct, pcmccartney1.  The LON ascii command is what I was sending to trigger (read).  I was getting a write success bit back on the plc, but I was not seeing the camera trigger.  LOF is the trigger stop command.  If I opened terminal on a PC, the same LON command starts triggering the camera.  LOF would then stop triggering.  That's where my confusion (lack of knowledge and experience) comes in.  Why would I get a write success on the PLC?  Does the write success ignore any sort of feedback?
  11. Click PLC and Keyence SR1000 barcode reader

    You are right, there is an RS485 port.  The programming port can also be used as RS232.  Hopefully NevergoldMel can chime in.   I've used RS232 on the Click before, but never for ascii (you have to choose ascii or modbus  protocol with the click).  My send and receive show up as successful, but I am not seeing any data (send isn't commanding the picture).  I think the issue is more on the side of the Keyence.      
  12. Has anyone interfaced an SR1000 (or similar keyence barcode reader) with a (Automation Direct) Click PLC?  I am looking to read/write rs232 so I can get the string back from the barcode reader, instead of actually teaching it or using banking (banking is a bit cumbersome with the keyence, plus it'd take me a long time to actually get the labels I need to teach the camera all).  I had started messing around with the application, but I have no way of seeing if the camera or plc is actually reading/writing the data.    Data is all ascii.   Thanks,
  13. multiple HMI's TIA Portal V13 S7-1200

    Thanks Excalibulles.  I have a copy of the Proface/Schneider manual, but it doesn't really answer my particular question, although it alludes to the answer that I do need to add the HMI to the project.  I am trying to confirm that however, via someone who has experience.    
  14. multiple HMI's TIA Portal V13 S7-1200

    Hello, We have some systems which utilize TIA Portal V13  (CPU S7-1200).   We currently have a Siemens HMI (TP-700 Comfort) on the system.  I am looking to add an additional HMI to do some statistical gathering.  I am contemplating a Proface.   My question is this:  Must the HMI be added to the TIA project as well?  I tried importing tags into GP ProEX (Proface software) but was unable to.   Any other PLC I have worked with never required addition of an HMI to the project itself, but from what I have read and heard, any HMI's must be added to the TIA project.  Is this the case? 
  15. I am looking for ideas, info, and suggestions:  In our world of high cyber security risk, we have a common struggle of how to manage the computer software and admin policies needed to utilize that software, and the concerns of network cyber security.   For many of us (especially in larger corporations), it is a hindrance to do our jobs because of the security policies enabled by our IT teams.   What are some of the work-around things people are doing to be able to do your job with such a hankering down for security on your computers?  I  am personally going to move to running on VM on our host computers so I can get the admin rights I need, while IT can "lock down" the computers as they see fit.
