  1. 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
  2.   Hello, I downloaded the program from the M251 PLC program, using the SoMachine4.3 environment. However, the downloaded program does not compile because the library is missing. The library is from a different manufacturer. Is it possible to find this library on the M251 PLC device? is there any way?
  3. Yesterday one of the guys on the shop floor had a fatal error on a NX PLC. The error code points to a power interruption during program download. From what I hear it wasn't apparent that there was a power outage (maybe I didn't get the full story?). Regardless there was a fatal error and the only option seems to be to clear all memory. We did this but forgot to power cycle so had to do this a few times before we did more reading. After clearing the fatal error, we realized that all retain variable values were cleared. For this we had to manually input some values back into memory to get the machine going again.  Is there a way to store retained values into like a spreadsheet? We had to go back to some screenshots that I had taken to put some of our values back. It's ok but not entirely convenient. I remember you can upload the memory values from a CJ2 PLC and keep it as a .mem file. Then you can just download this again to restore the PLC memory values. I don't think the NX PLC has this? I am also reading up now on the NX PLC backup function. It seems like doing a backup will also store the retain variable values. Maybe this is the only way to backup and restore?

  7. Hello everyone,  I have a Panelview plus 600 ( I know it’s old but I’m trying to get it to work). It’s on a yogurt bucket filler, I don't have any application to run or to do anything. What software do I need on a computer to be able to transfer it to the panelview. Is this even possible?  There is nothing in the memory right now but how to I program it and what program do I use?  I’m in the Los Angeles area and even willing to pay for someone to come and do it.  I need to get this to work, thank you so much.

  9. I am working on something different. I have a Signal Speaker that uses binary inputs to play a certain song based on source configuration. I have to send 24v to the inputs of the speaker. I have 5 of them with 30 different configurations. I am currently trying to do this in ladder logic, RSLogix 5000. Steps done. 1. Assigned the 6 outputs tag names. This is so that I can shift the program to other machines if I have to and I just need to change the slot location, or if I have an output go bad I can move it with ease. This works. 2. I  created the 30 lines of  5 columns to match the binary method. This works.    a. I can manually toggle the output to cycle thru the binary table. 3. Currently working on the logic that when a particular alarm is activated... I turn on the outputs needed to match the binary table. The problem is destructive bit reference on the coils.  I was researching some but don't know what direction to go. How can I call the same output on different rungs? I have attached the .L5X to show what I have programmed. 4. I know the first rungs are wrong. That is what I am trying to fix. 5. Would there be a better way to address this, if so how? Any help would be greatly appreciated.     Speaker_Alarm.L5X Speaker_Alarm.L5X
  10. I am trying to online edit a program in a MELSEC QCPU, using GX Works2, but I keep getting this error "A file which does not exist in the PLC was specified" <ES:010a4022> Few weeks ago I had just online edited the same program in the same PLC with the same steps with no problem. There had been no changes to the PLC after that. Just all a sudden when I try to edit yesterday I get this error. Not an expert in Mitsubishi, just started learning the basics. Connection to PLC is by USB cable. Steps I followed to connect to PLC:    -Online > Read from PLC    -Select PLC Series: QCPU (Q mode)    -Select PLC side I/F Serial Setting: Serial USB    -Select all target program to Read, then Execute I am editing the file that I had just read from PLC Steps I followed to online edit:    -Online > Monitor > Monitor (Write mode)    -Execute the function below when mode is changed: Checked all    -Edit the program (basically just deleted one -||- contact and drew back the line)    -Compile > Online Program Change Then Bam! error get! "A file which does not exist in the PLC was specified" <ES:010a4022> I had tried Verify with PLC, but all results match. Is there something I am missing? Help much appreciated!
  11. Hi fellow PLC veterans, I am new in the PLC world so please forgive me if my questions read dumb to you..   I am just wondering if there are any newer PLC machines that can: 1. keep the program even after its battery is completely flat or faulty  (Is this even possible?) 2. allow users to copy and save the program somewhere so one can install the program again without the need/presence of the machine supplier What tools/software may be required?   Thank you for reading and look forward to your response :)
  12. Unconverted Ladder Code?

    Hi All, Please see attached screenshot: Whenever I want to save the ladder program or start simulation, this window pops-up. If I press 'yes' I loose the whole work. I tried to open existing program and modify it, but it did the same. When I clicked 'yes' I lost all modification and just the original program remained. (I made the program in the morning, opened and saved many times but it started popping this window later.) I work with FXCPU series, FX3U/FX3UC type, simple project in ladder. This worked well but now is not anymore. I use Melsoft GX Simulator! Can anyone advise why this is happening? It is very annoying! It is pointless to work on anything now! Many thanks

  18. FX-2NC-32MT PLC program Download

    Hi, There are two machine in the factory controlled by Fx 2nc PLC. One machine control part is not working. It could be for battery failure. But the other one is working properly. In this case can I change the battery?  After that,  is it possible, I upload the program from the good machine PLC and download it to the other machine PLC? Regards Sohel Ahmed
  19. Hello, We have a FX3G connected to a FX3U-ENET-ADP inside a main cabinet. We are then using that master PLC to collect data from 2 other fx3g plcs in a node:node serial network. I was assigned a small project of pricing out some wireless adapters so we can upload/download to the two slave plcs. My question is, is it possible to upload/download programs to/from the slave plcs through the ENET adapter and serial network in the main plc? It would save us some money if possible. thanks.
  20. Hi, I have problem with 5069-obv8s, trying to use it for a first time just to power relays and contactors. All outputs are in internal fault, even if their are not conected. The card is set to use single output as safety outputs. Additional power on LA+ and LA- ports is connected. I don't know what else should I checked to fix this problem. There is no problem in controler or this specific module just on all of outputs. Hope someone will be able to help.
  21. Hello all, is anybody out there who may read out a program that is stored on a telemecanique cartridge (more or less of 1993)? Program is still running on a TSX 47 40, but have an identical second cartridge. I would send it to him/her even if international post and do not necessarily require the cartridge back. Would be great to have the program as a text file / pdf / hardcopy. Any help appreciated!! Best regards Stefan
  22. I am looking for how others have set up vertical axis motions using the Kinetix 5700 servo system. I have a 2 axis pick/place unit with a horizontal axis (X @ 2500mm) and vertical axis (Z @ 1200mm) that works as designed during normal operation. X axis has no holding brake and Z axis has a factory installed 24vdc to unlock brake. There is a GuardLogix L81ES control system that handles the safety and control. On pressing E-stop/opening Gates the vertical axis will stop the motion, apply the brake and hold with no problems. (2198-D032-ERS3 Drive, 2198-P031 Bus Power, MPL-B430P-MJ72AA X Axis, MPL-B330P-MJ74AA Z axis) The issue that I ran into was an accidental download of the program without activating the e-stop and the vertical axis dropped unexpectedly when entering program mode on the processor. I am aware that this instance was my fault as the programmer, however I am also concerned that this might occur again in the future if the controller ever enters fault mode or someone else completes a download. I have done some investigation with the "ProgrammedStopMode" parameter on this single motion axis and attempted all 5 options and the vertical axis still has a free fall drop for a second before the brake grabs hold - so evidently this is not working for me. (Page 24 of Vertical Load/Holding Brake manual - https://literature.rockwellautomatio...t003_-en-p.pdf) I am curious if there needs to be something done elsewhere as the X and Z axis are set up as coordinated axis? I also am unaware if I need to preform some action/parameter with the bus power supply for this? The current state of the machine as it sits now is preforming a MSF in manual mode after 5 seconds of inactivity or 30 seconds in auto mode. This axis is usually in demand every ~22 seconds. This will shut down the axis after preforming a brake test on the vertical load and seems to function OK, however it is still in the back of my mind the issues mentioned previously if we ever enter a controller fault while indexing. Thanks for your insight
  23. What Is a PLC Communication Error?

    PLC doesn't respond to communication requests or responds negatively to such requests. A PLC communication error can occur between the programmable computer and the devices it controls or when the technician attempts to program the device. If anybody have idea then share i am fresher now i learn it from CETPA INFOTECH. I think this is the best place to ask.
  24. Hello, In my ladder program I have 7 different arrays (containing REAL values) all members of a structure and I wish to extract certain values from the arrays and put them on another structure consisting of REAL values (not arrays). Which is the best way to do that ? I tried AryMove command but I get an error "Conversion from REAL to ANY_ELEMENTARY[], ENUM[], STRUCT[] is impossible. To get a better understanding of my structures and arrays here is an example: Struct wheel_data Global variable SWheel of wheel_data rad[1...10] of real, vary[1...10] of real, varx[1...10] of real struct. 2 wheel Global variable Wheel1, .... , wheel10 of wheel rad REAL, vary REAL, varx REAL what I wish to do is to copy Swheel.rad[1]  to wheel1.rad,  Swheel.vary[1] to wheel1.vary, Swheel.varx[1] to wheel1.varx 2nd structure Swheel.rad[2]  to wheel2.rad,  Swheel.vary[2] to wheel2.vary, Swheel.varx[2] to wheel2.varx until I fill all 10 wheel structure instances with values Thanks in advance.
