Hi.
I came into a problem that was buried in my memory.
I had a list of modifications to do on 2 RSLogix programs. So I tapped in the IP, uploaded both programs and started doing modifications online. Just to be sure that I had the right version, backup management is kind of an issue with that customer. I haven't done a lot of Rockwell in the past 15 years.
So everything is good until I realized that all of the tag descriptions are gone on both PLC.
I Googled a little bit. Then I retrieved the latest backups I could find, placed each of them alone in a different folder and went online over them. It appears to have worked with the exception of missing descriptions on the tags I just had added, which was better than nothing.
I'm just wondering if it was my best option?
What's actually happening doing that? Is it kind of merging the tag descriptions of the "online" program using the tagname with what's contained in the .ACD backup (I think it's something like a RSS file within the .ACD)?
My biggest fear was that it could kind of "reset" the PLC doing so it could clip something in the field like during a full download. Heard nothing so far.
I'll know not to do that ever again.
I had another one in V21 (no idea why this one in V21) that I also uploaded at the same time, but the descriptions have followed, so since V21 / Logix Designer the descriptions can be uploaded?
Thanks.
