If you have an off line copy you can toggle the bit and download to the CPU
1st open the file on your program tree, then change the view to binary, find the S1/14 bit, double click on the 1 and type a 0 value (in my pic its a 0), then you will need to download it... not sure if you can change it while you are on line?? can you go on line?
I know we have talked about this before you may need to search it...
If you don't have a copy of the program then I think there was a way around it but I forgot, if I remember I will let you know..
see the pictures on what to do
hope it helps
Mickey said:How did you do the compare if you don't have a copy of the controllers program? Just curious.
tona said:I get what u mean, but my current copy of the code in my laptop does not match the code in the controller, i did a compare and there are 2 rungs that are different . Can u help me get a copy of the code in the controller, like i said bit S:1/14 is set and i cant upload or save the program. I dont want to erase the code thats already in the controller.
TWControls said:I'm not trying to be picky either, but do you know which two rungs were changed or anything? If you could reverse engineer those changes, you could simply make the changes to your offline program and download it. That's really your only choice.
Which processor do you have?
TWControls said:You mean a Micrologix 1500? Do you have a spare? How about the modified rungs? Do you have any idea what was changed?
The Compactlogix doesn't use RsLogix 500

I just helped a client access their 5/05 using the backdoor method. The SLC controller is still fully functional after 17 years. This thread is on the first page of a search result for "S:1/14".You do realize that you are replying to a thread from 2008 and odds are in the past 15ish years the PLC has been replaced and the problem with toggling the bit is in the past... long in the past
