    Go to the first rung you want to copy and select it, scroll down to the last rung you want to copy, hold down the shift key and select the rung. This should indicate all the rungs from first to last inclusive have been selected, now right click this selection and copy to .SLC library. The indexing should be carried out on this library file, when you are ready to put it into your new program just go to the position you want to put it and paste from the .SLC library file. (Forgot to add you need to select partial save when copying to .SLC library) Steve

    Select your logic that needs changing and right click on it, select copy as SLC library. Go to the program you need to add this logic to and paste from SLC library. Open the saved file (it will have the extension .SLC). At the bottom of the dialogue box (address load mode) select the indexed radio button then select 'edit index'. In this dialogue box it will show all the addresses used in this saved library file, you can now edit under the 'fix up' heading the addresses you wish them now to be. When the rungs are pasted into your program they will be pasted with your new addresses. I'm not sure if this is what you were after. Steve

    I've not actually used this instruction, but it would appear to be an incremental postioning command, there is another which is an absolute position command which I think would be better suited. When the power is cycled, at the moment the DDRVI instruction tells the drive to increment the value again so when the drive has incremented say 50% of the distance when the power is cycled, then its going to increment the full commanded distance from where it left off. With the absolute instruction DDRVA it will increment to an absolute position (Ie your final destination). Steve

    Just as an update, in case anyone else comes across this problem. The program was running perfectly well, but I couldn't get online due to this error. There is absolutely no problem with my program. The only avenue open to me was to re-download the program (which caused me a great deal of heartache due to the process). This cured the problem and everthing is back to normal, so what happened who knows???? Steve

    Hi all, I wonder if someone can shed some light on my situation? I have a complex program with a mix of ladder, SFC and structured text. All has been up and running with no problem for around two years and I have been able to go online with no problem, until today. RSLogix informed me that I needed to upload the program even though no change has been made since last online session and the program was saved before exiting. When I tried to upload, everything was normal until one of the SFC routines was actioned in the upload, when I got the attached message, then the upload was aborted. I have checked and verified the offline program with no problems. Has anybody come across this before? the PLC is 1756 L61 ver 16.22 Just to add, the program is running fine. Steve

    Does anybody know how to get the symbols and comments to appear on the online display, when I open the program on the controller to view online, obviously there are no symbols or comments, so I save the program and import the symbols and comments, but when I then try to view the online program it reports that the program has changed and requires downloading to the processor which is not possible without stopping the process. There must be some way to do this, can anyone help. Steve

    I didn't realise that it was a relay output card (thats what you get for typing before you read), however after reading the spec. for this card I am gobsmacked that the rated mechanical rating for these relays is 100,000 operatations. How can Allen Bradley justify the extortionally high prices the charge for these cards. Steve

    There are three distributors in Oklahoma, it would be a good idea to contact them re- your requirements. You will probably be pleasently suprised at the cost of the software in comparision to the absolutly extortionally expensive Allen Bradly. GXworks is probably the best route to go, it also incorporates GXDeveloper (older software for FX range). Steve PS. Just to add I have this running under Windows 7 64bit and Windows 10 64bit.

    Take a look at this manual http://www.google.co.uk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&cad=rja&uact=8&ved=0CCgQFjAB&url=http%3A%2F%2Fwww.fapro.com.tw%2FDB%2Fdownload%2FMitsubishi%2520PLC%2520Manual%2Fjy997d16701l.pdf&ei=PZ92VYHXN5DB7AaU-oGYBA&usg=AFQjCNG8MCvHE6ZYhdd206IbSPUiq4Kx_Q&bvm=bv.95039771,d.ZGU Steve

    Thanks Delbert, I had already decipherd the manual as you say it's very simple, just for those who may need to know, here's how you get the current active screen number back to the PLC.

    Is it possible to have the HMI send the active screen number to the PLC (FX3), also perhaps have the PLC switch to a particular screen number? I've been pouring over the manuals but they are as clear as mud. Thanks Steve
