[?]: RSLogix 500 ladder has disappeared

[blukrr]

I going to try to describe it but it will be better if you take a look in the pictures I´ll be posting.

So part of the program (about 15 ladders) simply disappeared, others are still visible.
The program goes online correctly and the PLC is doing his thing better than ever, but still I just can´t edit those specific ladders because it´s not there to be edited.
A couple of days ago the program was only showing the ladder code when offline, but now it disappeared from offline too.

Sorry for cutting off the images but the only hosting site I could access from work would only allow me to post 150k pics.

Im confused !
The programme you are using is Logix5 and not Logix500. Logix500 files are .RSS

Try creating a new programme. Go online with emty Logix5 and upload.
If this works, you should export texts etc. from a previous backup and then import these texts to the uploaded version.

well i guess in the midst of all of this I forgot about the details and didn´t pay attention to this.

We actually have PLC 5 and SLC5/04 over here ther might have been some confusion (which should´t be allowed by the program anyways) I don´t know how this happened.

Thanks it was of great help your remark.

one question. is it the PLC's still running normal with your process when this happened ??
if the plc still running normal with your process that mean the logic is still there right. you just create the new RSlogix file and try to upload it to your PC and compare it and save it.

unfortunately if have some problem with your process that mean maybe there some thing happen with your logic inside of the PLC. probably this caused of the program are erased by somehow or memory occurred error or may be your are forgot to transfer the modification logic to PLC after your last edited.

Yeah, the PLC is running fine, but I have some things to change in the program but I just can´t because there is nothing to edit

I might be checking this issue today here at work and will provide some follow ups if got anything resolved.

Thank you guys.
