  1. After getting my logic to work. I went in and implemented the logic with my plc. It worked but in order for me to test part 2 of it, I have to turn the machine off and turn it back on as part of a reset feature. When I turn the machine back on, it wipes out my logic and goes back to its default logic. It's almost like I never changed anything. I connected my pc to the plc and connected to plc, pulled up the code and ran it on "Online Mode" where i can make changes and send them to the plc and yet again it wipes out whatever changes I had made and goes back to its default. Any suggestions?
  2. So a little new to PLC's especially Omron PLC. I have this machine from Japan that uses Omron CP1L which needed some modification. I made the modifications and uploaded it on to the PLC. When I try to put it in "run" mode it gives me the "Failed to change the operating mode the operation mode may be still changing in the PLC" error. After that the machine does not move even with the orginial plc logic. At first I thought it was my logic and so I double checked and did it again. Same thing occured. Has anyone experienced anything like this? How can I fix the PLC? Thanks
  3. CP1L-M40DR-A PLC does not boot from my logic

    Update: One of the tech's turned one of the DIP switch into ON mode which overwrote my ladder logic everytime at startup. Flipped that switch off and implemented the code again and it works just fine now.
  4. CP1L-M40DR-A PLC does not boot from my logic

    Logic meaning in terms of my ladder logic, apologies for the confusion. Basically I have a machine that cuts some stuff and I wired safety curtain sensors to it. If anyone breaks the sensors the machine shuts down as a safety feature and then you'd have to run it back on manually via a on/off switch. I added 3 "no contact" statements within a already exisiting ladder logic and sent that to the plc.
  5. CP1L-M40DR-A PLC does not boot from my logic

    Cannot use memory card with this plc. Checked the dip switch settings and nothing is out of place.
  6. Update: The problem was fixed by just unplugging the power and let it sit there for a few hours. No idea how but it works.
  7. A sales specialist reached out to in regards to the software some time ago, probably few months ago. So I basically sent her an email explaining and if I can get Technical suppor help on the matter. Have not heard back from her yet. I will send technical support an email as well as try to give them a call. Thanks Gtsuport
  8. Yes sir that was my speculation at first, so I bought a brand new cable, switched the cable I was using and tried again. Still ended up getting the same issue. After transferring program "To PLC"  did you use "Compare with PLC" feature to make sure that both codes matched exactly and it was "Compare Sucessful" after that I into "Operation Mode" -> "Monitor Mode" = "Failed to change operation mode. The operation mode may be still changing in the PLC" Went to "Run Mode" = "Failed to change operation mode. The operation mode may be still changing in the PLC" I tried to get in touch with the Omron Technical Support but I have heard back from them ever since and it has been 3 days.
  9. When I put it in monitor mode it give me the same error. But when I am "Work Online" with the plc, I can see the inputs light up when I press the input buttons etc. The full part number to the plc is : Omron CP1L-M40DR-A I am not using any expansion modules or any other modules, just what it comes with already. I am connected to my laptop via USB. I thing I have noticed is sometimes my computer crashes at times when I pull the usb cord from the PLC side or computer side. It also crashes when I turn the plc switch from on to off and back on. thank you, any help would be appreciated.
  10. CJ1M problem

    I am having the same issue right now with an Omron CP1L. Everytime I connect to the plc and transfer my logic and put it on "RUN" mode, it gives me the " "Failed to change the operating mode the operation mode may be still changing in the PLC" error. Not sure what else can be done.
