  2. Crouzet Millenium 3

    Recently had to get a program out of a millenium 3 plc which I had programmed a few years ago but the cable would not connect.The only difference this time ,as my laptop no longer had a rs232 port,was the use of a USB to rs232 converter. Having trawled the web I managed to find the circuit of the interface cable below. It looks like the signal from the computer uses the negative going part of the pulses which aren't present on most usb to rs232 converters. Is this correct?

  10. 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.

  12. 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!
  13. 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 :)
  14. 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

  24. 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.
  25. 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
