  1. Based on what I can google, it is not possible to copy bits over as a block from one variable to another if one of them is a structure? Anything related seems to be someone struggling to access bits and being told to use a union, but that's not what I'm after. I would like to map a structure of equal size to a byte/int/word and vice versa, as shown in the attached image. Thanks!  
  2. Hi, im doing safety programing and then im testing the program some of the lines wont change state. the lines that are green is true ans black is false. but why are some of the lines yellow? any smart fellows that have an idea? many thanks
  3. Hi, I have a reset button for a safety function, and I want it to either flash in one state or light up constantly in another state. However, I can't find a pulse generator in the safety Function Block (FB) in Sysmac Studio. Do you have any tips or suggestions on how to achieve this? Kind regards, An Apprentice

    What Does High Limit clamps and Low Limit Clamps means in Rockwell Analog Out Module. I understand What High Engineering and Low Engineering value (8191 as High and 1638 as Low) What Does clamp Limits Do? Generates Alarms? Can any one please explain me in Detail that would be very helpful and also If I can get a link to documentation if anyone knows that would be Grateful.   Thank You

  6. Let me start off by saying that I have 36 plus year of experience with Industrial Automation and Robotics and take great exception to the sensationalism expressed in these headlines.  Please allow me to rant and hopefully save another young engineer from a similiar mishap. https://www.foxnews.com/us/robot-attacked-tesla-engineer-at-texas-factory https://nypost.com/2023/12/26/business/tesla-factory-worker-attacked-by-robot-which-dug-claws-into-back-arm/ Websters tells us that an attack is "a belligerent or antagonistic action".  Such action is by definition not possible by a non-sentient piece of automation equipment. The American Industry Standard for Robotics has been ANSI-RIA 15.06 and it clearly states that anyone entering the working envelope of a robot must posess the Teach Pendant or Alternate Disconnect Means at all times.   Now reading the articles it appears that this was a multi-robot cell as the "engineer was programming two other robots in the cell."  Thus if his work did not involve the Third Robot it should have been under Lockout-Tagout_Try per OSHA 1910.147.  Had that been the case this catastrophe would not ahve occurrred.   If the Third Robot needed to be under power then it's pendant or disconnect should have been in the control of the Enginner and the 3rd robot limited to slow speed allowing for stopping when the errant action occurred. There is another possibility I would mention, something malfunctioned in the controls design and the safeties the Engineer thought he had, did not operate as intended.  The designer in this case will need to explain what happened. In closing , let me point out this incident occurred in 2021 and this is 2023 almost 2024 and we're just hearing about it.  If the Industry really wants to get better we'll "Fail Forward" and teach other robot users what actually went wrong here and make sure others don't have the same mishap.  That Mr. Musk would be a world class response. 
  7. Hi there! I've been looking for some fault codes table for the 1734-AENTR adapters, since I'd like to show a message in HMI with some information when there is a faulty adapter, but I haven't found anything on the internet. So my question is, is there any type of table like this for these adapters? Right now I have a PLC with some AENTR adapters in the program for testing, and since there is actually no adapter connected to it, I can see a 16#2024 error in the module properties, but can't seem to find that info in the module variables.   Do you guys have any clue on how to find this information in order to show it?   Thanks in advance!
  8. Hi, I have a 1734-OB8E module on a POINT I/O system. In the hardware configuration, everything looks fine. However, I am not able to energize any outputs on the card. What could be wrong? Working in Logix5000.
  9. Hi All, I need access to a the Safety function blocks within a safety CPU using sysmac studio on a machine we are upgrading.. Is there a generic password available to gain access? Best Regards, Paul  

  10. Mitsubishi safety relay

    ABlearner posted a topic in Mitsubishi

    Hello guys! A would like to set up a new inverter for my existing machine. I wanna follow the recomandation about the safety wiring. The only problem is I need one more, Z safety output. I checked, there is official expansion unit, and it says I have to only connect the EA, EB, EG, and EP terminals ? Do I have to connect again the X0, COM0 ; X1, COM1 terminals, because I want actually the same inputs, just I need one more safety relay output. I attached picture about it, thanks ahead. 
  11. Hello group, Is it possible to copy the data string from a 1734-IB8S to a datatype such as an INT or DINT? When setting up the I/O with a Safety PLC, the discrete I/O is setup within the Safety Program but it's contained within the program itself. To utilize the same I/O points in a Continuous task requires inserting and remapping the I/O points to essentially the same tags. If the I/O data could be moved/copied to a global datatype within the Safety Program, it seems like it would reduce any redundancy in the Continuous tasks.   Anyone done anything like that/ Suggestions?
  12. Hi All,Cx-Supervisor, NJ501-1340, Sysmac Gateway.I have been writing an update for a project and converting to this new controller.It's a pretty big project.Using a combination of Ladder and ST.Using Cx-Supervisor 3.5.I created some new Variables in Studio and made them Publish only.Started to create Points in Supervisor and made them I/O connected to the variables in Studio. No problems everything was connecting and working just fine.Then one of the points would not update. I could change it in the PLC and it would not change On the HMI.I deleted it and recreated it and it did the same thing. (sometimes points in Supervisor just stop working and recreating them fixes it).I then copied the control and pasted the old point into it and it did the same. Then other started to fail. Showing no reaction.I stopped the gateway and restarted, no help, I rebuilt the HMI, nope.The can check the tags in Sysmac gateway and they always change when the PLC changes but not the HMI.I checked the point maintenance in Supervisor and it would not change.I dumped all the affected variable in the PLC and in the HMI and recreated them. Then it got stranger.I could change some on the HMI and it would show in the PLC but not the other way.This is on Bools and UINTS.Stopped CX-server, tried using it with Win8 compatibility. nope.Pulling my hair out now. I should be coding but I'm trying to get the apps to work.Any ideas will be used with thanks.Peter
  13. Hi, So I have a problem, that BootP DHCP server doesn't find my 1734 AENTR series B and so I can't assign IP address to it. Been trying many things. Any advice? I'm new to AB and I guess it may be a really easy thing but so far I didn't find a solution. 
  14. I have a question regarding hazardous zone design. My control cabinet will be in safe area but I need to have e-stop and safety limit switch located in hazardous area, Div 1 Zone 1. I am assuming that I can use zener barriers or isolators between the field devices and safety relay. I just wonder if the safety relay will function properly with barriers in between? Also do I have to use 24VDC safety relay for this application? I don't know what voltage/current is present on the terminals connecting to safety devices.
  15. Hello,  I am using Omron’s safety G7SA to relay 24 volt line. But the strange thing happening is that, one relay’s output is only 5 voltage, even the relay is on. I exchanged relays, it remains the same. Maybe the base socket is problematic?  Or is this just G7SA failure? 5v (exactly 4.96v) is strange. Please give me some advice.   Many thanks in advance.   Ting    
  16. Hi. I have been up, down left and right in sysmac looking for the safety cpu's to add. If i open a project that has these devices, "Safety CPU device" shows in their toolbox window, while my project that does not have any safety added (trying to), does not have the "Safety CPU device" in toolbox. Any idea how to get it to show up so i can add the SCPU?  
  17. So im looking for recommendations on a safety PLC application, and I'd like some advice. So the addiction is zero motion detection, were using a 5069-L306ERMS2, 5069-IB8S, 5069-OBV8S. What id like to know if its feasible and safe. Can a zero speed detection code be written and safe in a PLC? I mean you can buy a zero speed detection safety relay, and two generic sensors , one PNP, and one NPN, and its just watching the pulses to happen in a predetermined manor and that both transition in the correct manor and that they both stop. So why or why not do this in a PLC? Any advice on how to do it, and considerations or advice?  What are peoples thoughts and or advice?
  18. Hello. We are looking for a safety scanner that has CIP safety(Ethernet IP) or fSoE (Safety over etherCAT) that is combability with sysmac and NX102 cpu. There is a lot of safety scanners on the market that support CIP safety and fSoE and I have tried to load in both EDS  and ESI files into sysmac with no succes. Of course the best option would be that OS32C safety scanner from Omron themselves would have build in support for Cip safety at the moment it only support ethernetIP to read out data for diagnostics.   Is there anyone that is running a safety scanner with sysmac with CIP safety or fSoE ?  If you do I would be very happy to receive the brand from the safety scanner manufacture.   /Best regards.
  19. Hello, My coworker and I are commissioning a new panel. We have a 1732-AENTR series C remote IO thats Rev 6.1. The project file from a previous identical panel has the module at rev5.3 in the project tree. I downloaded the AOP and ran the installer, it worked no issues. My co worker then did the same thing but now the module is unrecognized in the project tree and the module is missing after installing the AOP. Im concerned he corrupted something. I tried uninstalling and reinstalling the AOP but no luck. It works on my computer but not his? TechConnect said something about corrupting the aop core. My coworker did the first install and he was getting confused about zip files and the virtual machine we run rsl5k on. Maybe he broke it? any suggestions?
  20. I have an analog output card 1734-OE2V and there is in the fault/actions page parameters for program mode. What is program mode and when it is activated? Fault mode is clear but... Program should be written the value, but when this happens?

  21. File Copy for NX/NJ

    Graemek25 posted a topic in NJ Series / Sysmac Studio

    Hello, I have used RSlogix5K for years and I am now creating NX/NJ PLC program.  Is there a similar command to 'COP', which can copy ALL the data from a structured variable to either another equivalent structured variable or to a data array of some kind - e.g. a byte array?  I thought the MemCopy command might do this but I believe it only handles arrays, not structured vars. Many Thanks Graeme
  22. Hi guys,  Can someone explain me what is the difference between SS1 and SS2 instruction ? I read the help but its not so helpful for me.  THank you so much.
  23. Hi,  Can someon help me with the following question. Like what makes a Kinetix 6000 drive a Guarded drive ? What type of safety stuff can you set to make it more safe.  Is it some parameter ? I am bit confused, by the manual. Should I active it in the PLC program or how ? Or it is some setting like a safe speed or torque.  I would really appreciate any help. Thank you so much ahead.  Have a great day, thanks for the reading.
  24. Hello guys!  Im using RS Logix 5000.  Can someone explain me what is the difference between when a servo is shutdown or disabled ?  I read the help but it says the same. I can assume it like when its shutdown, there is inside some circuit which is not allow the 3 phase for the drive.  Disabled is that when it have the 3 phase but nothing can happen ? Is there any difference with the break ? Like when its shutdown it can rotate until its slow down by itself or the break will be active ?  I tried to uplod a pic but it was not succesful. When you open a servo axis properties and you choose the Fault actions tab. You can find there these settings.    Thanks a lot. 

  25. 1734-IB8S "Blip"

    KathyPatrick posted a topic in Allen Bradley / Rockwell Automation

    Question from a PLC newbie....  We had a "blip" during a thunderstorm where we saw multiple signals on a 1734-IB8S point I/O transition from true to false for ~ 4 seconds (based on our DCS history from a serial connection).  There are several other modules on the backplane, and we only saw state change on this one card.  The 24VDC power is sourced from T-0 for points 0-3, and T-2 for points 4-7, so we don't suspect a short.  It's been suggested that we either had an I/O card "blip", or temporary loss of power to our field contacts (limit switches) caused by dust/vibration of the removeable terminal block.  Our controller is a 1756-L73S GuardLogix 5570.  My question is should I expect to see an I/O fault in the Minor Fault history (we did not)?  Would an I/O fault necessarily show up in this history, or does it need to be configured somewhere? Our points on this card are set up as single points with test pulse from T-0 and T-2.  We are reading status of limit switches in the field. Thank you in advance for any response. Kathy
