  1. Geo1000

    Hello all, I have a problem with PLC at work. I am working on historical code with a view to upgrading it for a roll out program to all site based PLCs. The code is to be downloaded using memory cassettes, and there is data on the PLC's which needs to be retained. I have re-worked the code and it performs as I would expect as per the following: 1) I download original code (V2.01) to PLC using CX1 2) The PLC simulates a cycle and various values are stored (the key variables are Installation Date and Service Due date). 3) I then download my code to the PLC and the variables have been retained. All so good so far.   The problem is that the factory production line uses PLC code saved using the PLC Backup Tool. When I download the original code to the PLC using this tool, I encounter various issues, but the main one is to do with real time PLC clock values. When I download the code direct from CX one developer,  I use the MOVD(083) instruction on A352 through four to give me a variable with the date, month and year. This morning (29/01/2019) the BCD values read as 41, 1 and 25, which translates to 29 (0010 1001), 1 and 19 (0001 1001). When I download the backed up code using the PLC  Backup tool, the values are totally different. I have run the backup files for both codes through a comparison program and there are no differences between them at all....... Can any one advise if they have experienced this before??   Thanks.
  2. MAC E300 backup

    Hi everybody! I should help to upgrade some automation equipment, that has a FX2n and MAC E300 onboard. I.e. all SPS are quite old, obsolete and discontinued in production for a long. So will be useful to make an uploading of program from the HMI, otherwise, when it may die, all autmomation system will  die... However, in contrast to the PLC program, the program in HMI is password protected for upload and download. Excuse for my question, but is there a way to bypass this password without losing an HMI program. Thanks in advance
  3. Panel view plus

    What is the best way to get to the configure screen when the mer file is set to auto run on the hmi. I need to get this file out before this screen finally quits on me. 
  4. recover program from plc-5/15

    A machine was bought at auction which included PLC-5/15 module.  It did not come with a backup of the program.  Our maintenance technician said the program would not load and turned the module over to me (IT).  I notice the battery was installed in '92 so am assuming the program is lost.  Is their any internal memory or last ditch effort i can attempt to recover the program from this module?
  5. iFIX restore problem

  6. C200H CPU23 MemoryUnit Backup

    Hello, first of all sorry for my english skills. I've got two questions about a 20years old PLC from Omron (C200H CPU23). This PLC is still working in one of my machines and I have also a second one for the worst case scenario.... Now my Questions: If i take the Memory Unit (EEPROM) from the PLC 1 and connect it to the PLC 2 is my machine still running ? Did the PLC copy the programm automaticly from ROM to RAM and             everything is fine? I also need a backup of the Memory Unit (c200h-me831). What are my options? Did I need a programming cable, Software (CX-One?) to make a Backup of the Program to a second Memory Unit?   I hope there is someone who worked with this kind of PLC. Thanks a lot for helping me Greets Andy  
  7. SIEMENS S7 STATION

    Dear All, I am very new to S7 PLC programming (S7 Simatic Manager v5.5) and I wanted to know how to back-up a system consisting of multiple PLC Stations (S7-1200, S7-300, etc). I am able to upload station to PG but that will save only per station. How about saving the whole system? I am not sure if i am using the right terminology. As you can see, I was given a zip file for the S7 project and it contains the whole system. I am trying to see how the commissioning engineer was able to do it (don't ask why I am not asking him instead). How can I then use this project file to download the program to the PLC/system once I decide to restore. I am at loss and have been searching for references over the internet. Uploading and downloading per station is no problem. I cannot seem to know how to do it on multiple stations system. I hope I have made some clear question or somehow you have managed to understand it.  TIA.
  8. Hello, My quest is to make a memory card, which I can just put into my PLC on the field and load all program and options etc to my plc. Now i found the official omron guide about it but its not good at all... For example is does not explain that how i need to transfer the H and D memory part to the plc, and that not all network settings are being copied if im not careful.   But my question is: is it possible to make this backup memory card without having the actual plc? Because the process is done in memory card window, which is only available if you are online. So basicly i have to get all the plc rack parts to make this work? I tried with the simulator but ofc it is not working.   Someone mentioned me that it is possible he heard from someone but no one actually knows how to. And there is nothing in the omron manual as i see.
  9. CPM1A Backup/password

    Hi all, I hope one of you kind people could help me: I have an Omron CPM1A CPU where the outputs are damaged. I have a new blank CPU and I would like to transfer the program, however, the UM is read-protected. The backup tool doesn't seem to cater for the CPM1A. Is there any other way the program could be transferred? The customer does not have the program or the password. I do not believe that I am interfering with any intellectual rights here because the OEM are long since departed and all I want to do is transfer the program, not modify it. Many thanks in advance. JG.
  10. A2SH PLC

    I have encountered memory backup battery failure/fully drained in MITSUBISHI A2SH PLC.So RUN LED started flashing on PLC. Thus no field parameters values were being shown on HMI. I connected PC with PLC through serial RS232 cable using GX DEVELOPER 8 , the connection test was successful. Then I tried to download my project saved on PC to PLC, then I was amazed as It asked for a keyword. However when the backup battery was working , I downloaded the same project but it did not ask for any keyword. Can anyone explain this. Now the real problem is that the program was developed by somebody long ago , to whom I don't have any contact right now and I m helpless as I don't know the keyword and can not download the program and thus my machine is at halt. I tried to clear the user memory from online menu , but it says the function not supported. I m stuck and frustrated . Anybody 's help is greatly appraised in anticipation. Of course I m not asking for hacking a keyword. Just to know how can I make my system functional. Thanks everybody.
