  1. 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. 
  2. 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  

  3. 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. 
  4. 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?
  5. Hello, I am trying to flash an indicator light (Banner  K70LBGYRPQ ) every .5 seconds.  The PLC manual says 2.5A per channel.  The light uses roughly 113mA max current @ 24vdc.  I am using output 0 to do this (O:0/0).  I think I may have ruined the output by flashing the indicator light.  Has anyone ever experienced this before?  Is there a minimum pulse time for this PLC?  What do people normally do when wanting to flash an indicator light such as this?  This is not the first time I have seen this happen.   Thanks in advance!
  6. 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    
  7. 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.
  8. 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?  
  9. 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?
  10. 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.
  11. 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.
  12. 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.
  13. 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. 
  14. Hi. I would like to ask that like you guys are when using a kinetix servo motor what type of safety conditions are possible ? I found a fault actions label. Is there anything else like between the parameters or so ? Thanks ahead. 

  15. Safety PLC R08SFCPU

    Dirk van Zyl posted a topic in Mitsubishi

    Good day Guys I have been working with Mits for a while but i am new to the GX works 3 setupp. We are looking at using R08SFCPU PLC with a RJ71GF11-T2 for CC-Link IE Field in order to do safety. No i think i understand the normal IO on this device but the safety i just cant get to a point to understand what is happening. When i try to address it SA\X0.... then it says it is invalid. Does anyone have an idea how to do the setup for safety or a manual that describes a bit in detail.   Thanks
  16. Hello All,    I have had no luck sorting through Pilz datasheets on this CPU to find cable / software to connect/upload the program. Any insight?   We are upgrading this to the CPU 4000 series - it will use DeviceNet. Will this node number / memory allocation be setup within the 'PSS 4000 Firmware' software? Where do I find a guide for this?   Thank you.
  17. Hi everyone, I have an annoying fault on my Kinetix 5700 drive: M01-Safety Feedback. I know this fault is generated by  the SFX instruction in my Safety program that sets tag: "Axis.SFXFault" to 1. The problem is that the instruction is NOT in Fault (Fault code 1 = no fault). This error occurred after Safety encoder 843ES lost it's IP address. I used Bootp to set it gain. And reset the SFX instruction. I can see the encoder in studio 5000 rev 32.12 running and ok.  Does anyone encountered this problem? How can I clear the fault?   Thanks

  18. Siemens IEC 60870-5-103

    Lmv posted a topic in Siemens

    Hello!, im having some troubles communicating Siemens Relay 7SJ622, with the IEC 60870-5-103 protocol, with some SEL controller, i don't have any signal of the slave relay 

  19. Siprotec Relay 7sj62

    ranakki_99 posted a topic in Siemens

    I have 24 Siemens Siprotec relay(7sj62) which i want to communicate with Scadapack 330E (Schneider) on 103 Protocol. but every time I try to communicate it shows Slave device is failed to communicate. trying to communicating via serial (RS-485). What should i do..?? or do i need to communicate it with Siemens PLC..?? If so which PLC should use..??
  20. Good Afternoon  im a complete newbie when it comes to PLCs but have done plenty of PIC programming in the past. I've been gifted a couple of FX0s 20mr units to try to repair something I made with PICs years ago. It got damaged during a move and I can’t see well enough now to make PCBs anymore so thought that this might be a solution. The basic operation is  1. switched on 2. motor A moves till hits limit switch (X000) 3. Wait 2 seconds 4. motor reverses till hits second limit switch (X001) then once this has been completed then the following  5. Motor B turns clockwise for 30 seconds then stops  And while Motor B is turning I need Motor C to turn until hitting limit switch (X002) I then need to get it to repeat on the press of a button but I need to reverse operation of Motors B and C I am using double position relays to drive the motors so motor A is on Y000 and Y001 if I power either relay the the motor turns in that direction. Same with Motor B and C Y002 to Y005 is this something that’s possible with one of these controllers or am i going to be programming a PIC to control the PLC ?   All the various COM and powers are connected up, I can individually make every motor do what I want, but the program doesn't flow from one item to the next. but this is probably just me

  22. CC Link Inputs (limited to 2 words?)

    NomadAuto posted a topic in Mitsubishi

    Everyone, Using a Q series Mitsu PLC interfacing with a M1P Pilz Safety PLC - and only receiving 32 bits from the SPLC. I have the station setup in GXWorks2 as a device station (occupying 4 stations). I am receiving only the 1st station of the 4 designated. (It is node 9 in the snippet) Any tips on this? (First time posting btw) Thanks, Elliot

  23. MC protocol

    sczot posted a topic in Mitsubishi

    Hello once again, before I'll dive into mitsu manuals, does anyone of you know if there is some special relay signaling that PLC (FX3GE) have lost communication via MC protocol? Thank you in advance
  24. Hello,  I got Allen-Bradley  1769-L36ERMS, AB Powerflex 755 and 20-750-S3 safety card.  According to: https://rockwellautomation.custhelp.com/app/answers/detail/a_id/946912 „"There is NO Integrated Motion / CIP Motion support with 20-750-S3 safety card” so I want to run hardwired emergency shutdown system.  How can I configure this module with safety card in PLC?

  25. Relay Digital signals

    graemeian posted a topic in CX-Programmer

    I have a CJ1M-CPU13. It will be used for a prototype and later if successful, a better PLC fit will be employed. This system does not have the ability to drive pulses for servo control. However, will this system relay a digital signal at ~1kHz? I also need the PLC to count the pulses, reset at 1000 and start again continuously and never miss an input pulse. I see that the published transactions give  <15 microsecond decision times. I would think it would be no issue. Thank you.
