Safety grayed out in 1768 L43S

I am working on a Compact Logix and am unable to view safety routines.

I can lock/unlock, even generate new signature, but I cannot view the safety logic. It makes no change if I am online or offline with the safety locked or unlocked. Cross referencing a Safety Tag from stand logic shows "Source Unavailable"

I borrowed a co-workers laptop as a quick check, and could view and edit safety, but the standard logic is all grayed out and unavailable.

Attached are screenshots of what I mean by "grayed out"



I am guessing there is either a computer setting (maybe missing some config files) or something to do with how I have comm set up to get online. I usually work with Control Logix and have never had an issue viewing/editing safety logic.

Any Ideas?

What version are you running? Maybe its a Minor rev level incompatibility?

Because I am pretty sure I am doing something wrong, attached is the path I am using to get online.

I am using slot 0 in the 1768 bus. I am unable to select slot 0 of the 1769 bus.

This is my first time working on a CompactLogix so please point out the obvious!

RSLogix is version 20.04 and the controller is firmware version 20.11

There is really no difference between Controllogix and Compactlogix on safety other than the obvious h/w. Everything appears right; the slot 0 you're concerned about on the two busses is correct and can not be anything else.

see if the information in this link helps ...

there's a link to some Allen-Bradley reference material at the end of that web page ...

if my GUESS is correct, then you need access to a small file named "sk.dat" as a "key" in order to open these protected files ...

Only certain versions of Logix Designer can edit Safety. Which version do you have?

Wow Thanks Ron, I did not even know that source protection existed!

I think that this is definitely what is going on.

So from what I have just read, it looks like I am out of luck. In order for me to gain access I need the Key, and the keys are all user generated (unique), so I cant just get it off the Rockwell Knowledgebase or anything like that.

The laptop I borrowed belonged to a guy from the original manufacturer of this cell, so he probably had the key. I was just contracted to add some tooling and a robot to it and they never gave me the key.

It's not a big deal for this project as the safeties were all done before the guy from the original manufacturer left. It was more the knowledge that I was after in case I ever run into this again.

In the future I will need to ask the customer if there is source protection.

I am going to contact them and see if I can get a copy of that key just so I know 100% that this is what is going on.

Thanks so much for that link!

I have edited safeties on numerous other PLCs, just never a CompactLogix, and I can lock/unlock the safety of this PLC so I definitely have the right version.

Thanks

Ron, This is definitely my issue. It appears that the plant actually protected it as I have just opened up the OEMs last file on the original install (2014) and I can view all the safeties etc. It isn't until after an upload that I lose access in that file.

I am confused why the guy from the OEM had access with the 'same' file that I was given.

I will definitely read into this more but at least I know what is going on now.

Thanks so much!

glad we were able to help ... by the way, you're not the first to be "surprised" by this feature ...

be safe ...
