    I believe you will need your HMI target to be a Windows PC rather than a Quick Panel View/Control.
  2. Ladder Logic Daily Energy Consumption Calculation

    What signals do you have available to you?
  3. 90-30, Load program from PLC errors IC693CPU313U

    That message in Logicmaster tells me the program and configuration in the PLC were created using VersaPro. That means you can't use Logicmaster to extract the program. To do it, you will need the version of VersaPro that supports the 90-30. Have you tried contacting your local GE distributor? Maybe they can get you a VP installation CD with the correct version. That's a rather large program for a PLC with only 5 I/O slots.

    You won't be able to use your instance of VersaPro with the 90-30. What you have is only good for the VersaMax Micro and Nano models. As you can see by the copyright date 1999 was around the time of transition from Logicmaster to VersaPro, so the program could have originally been written with either package. Early versions of VersaMax were quite buggy. Many long-time Logicmaster users delayed making the transition as long as possible. The PLC should be new enough to be compatible with the version of Logicmaster you have. The only compatibility issues I ever ran into with Logicmaster were with very old firmware versions of the PLC. Logicmaster 9.02 was current in the time period when the unit was installed. CPU313U is firmware version 8.4 which dates to around that time period. However, if it was programmed with VersaPro, you will not be able to extract the program from it with Logicmaster, no matter what version you have.

    First and foremost. Your interpretation of the terms "Upload" and "Download" is the opposite of the way both Logicmaster and VersaPro define them. Be very very careful that you don't accidentally erase the program. For example, if you were to create a new project folder with no logic in it and then perform what the software calls a "download" you would wipe out the program in the PLC. To the software, "download" is the transfer from the PC to the PLC. What were the exact words in the message Logicmaster gave you? How old is the PLC? You may not have the correct version of VersaPro. They sold a version that was limited to the VersaMax Micro product line. That version can't program a 90-30. It is also possible that you created a new project in VersaPro for a VersaMax Micro PLC instead of for a 90-30. If that is the case, create a new project and select the 90-30 as the PLC model. To do that, launch VP but don't open a project file. Then, from the "Tools" menu, select "Options" and select "Series 90-30" in the "Default Hardware Configuration" window.
  6. Upload an application

    If it is a recent model of Quick Panel with an Ethernet port you will probably need Proficy Machine Edition. It gets more complicated with earlier models that used a serial link and an 8-pin DIN style programming port. That requires a special cable with a TTL/RS232 converter built into it. Also, the original programmer must have included the source code in the file he/she downloaded to the unit. If the only file residing on the QP is the compiled runtime file you're out of luck. Unfortunately there is no way to know if the source file is present is to try to upload. If the upload fails you will get a notice that the upload is not possible.
  7. Beginner PLC Project

    Go to your facility's maintenance shop. Find out who is the go-to person whenever there is a problem in one of your processes controlled by a PLC. Ask him/her the same questions you asked in your original post. If the maintenance department isn't the source of the PLC-controlled operations in your facility, they will be able to put you in touch with whoever is. You may find that there is already a trainer set up that you can learn on.
  8. Dealing with an output that is "always on"

    Solid state devices have some small leakage current in the off state. The magnitude will be detailed in the specification sheet for the module. If your is so small that you need the output to have zero leakage in the off state use a contact output module. That's what they're made for.
  9. Proficy and quickpanel

    If you have been sorting by address and then change to sorting by name, you see the full list of variables, prefixed by the target name as you original programmer described. When you then change to sort by target, you get each target included in the tree with its variables and the target prefix gets deleted.
  10. Received this question via PM

    The error message seems to indicate that the problem is with the project folder in the PLC and not a problem with the program in the PLC. You could try creating a new project folder, set it up for SFC when prompted and then see if you can upload from the PLC to it. That won't give you the rung comments and variable descriptions, but if it works at least you'll have a backup. I assume everything looks OK in the project file you're opening and trying to upload to?
  11. Proficy and quickpanel

    Once I installed the PC ladder component I was able to open your file. In the QP, there are two PLC communications drivers. One, with a device name of "VersaMax" is using GE SRTP which is Ethernet and it communicates with the IP addresses of the CPUE05. The other is GE SNP which is serial. The name of the device is "DSP". Can you tell me what it is?
  12. Proficy and quickpanel

    You mentioned ladder logic in the QP. That's probably what My installation of PME doesn't like. I never install the PC ladder engine when I install PME. If it lets me install that component without first uninstalling all of PME I'll do it and take a look. I'll let you know either way.
  13. Proficy and quickpanel

    I saw the part number and didn't recognize it. That's why I asked.
  14. Proficy and quickpanel

    Is that an old Total Control Products Quick Panel? I can't open your file because I'm lacking some component that your project has.
  15. Received this question via PM

    I received the following by PM: Hi Steve,   I noticed your name on a post related to a similar message I have: "Error during load; Program folder incomplete. Must reload or restore logic". In difference with the original post, I don't have lost of communication, my problem is that I'm trying to backup the contents of the cpu 351, I went as far as uploading the registers and the configuration but when I tried to upload the logic is when it fails and I get this message, obviously if I try all of them in one shot I got the same message. I'm using LM90 9.04 (DOS version), I tried using VersaPro but it doesn't understand the logic as it is comprised of part SFC and part ladder. I have use my laptop to backup many programs and never have this issue, as a matter of fact, I backed up another cpu 351 right after with no problems, I have also used other pc's with same results. My theory is that someone might have tried to connect with a newer version like Proficy ME and converted the logic so now LM90 cannot understand it. I've contacted GE already and they still haven't got back to me. Any ideas? Thanks for your help. I don't care to respond privately to PMs. I'd rather keep the discussion on the forum so that other people can offer suggestions and benefit form the exchange. Since you mentioned that the program in the PLC is written in SFC, do you have SFC installed on the computer you're using for the attempted upload?
