Can you explain what that is? I've not ever heard of it and can find no information on it.

I haven't either. I was looking for a example or I will make one up my self. It is a form to track plc programming changes. Changes made on the back shift or on opposite shifts. So you know what changes have been made to any plc in your plant

Does anyone use a paper like this?
I usually just write my own, I don't get fancy.
Just a plain text document with each section having its own date, what network/section, reason and small description of what was done.
I just did it for my own good, although there are a couple others who may hop on and make minor changes to the PLC.

That is what I was going to do. I didn't know if there was a form that everyone use's
I made mine simply because the person working my position prior to me had kept little to no track of anything, which scares me.
Mine usually looks something like:
Date: May 21, 2014
Section: CVTankAgit [LD]
What and why: DFB fixed to accept proper parameters and agitation on/off timing.
Whether this helps or not I figured I would at least give my example, whether it's proper or not I'm not sure but it seems to work well for me and my boss appreciates it.
cheers!

I use a change form here but it's primarily for CYA purposes. The production manager and the site manager have to sign it before we will make a change.
Very seldom should you need to change PLC code once the equipment is running and all bugs are worked out. The way we store our programs we have a word file that is a change log detailing what was modified and that is stored with the program and the change form.
We also have a running change log in the directory where all the versions are as we keep long version history on file.
I am the only person here who can change code. I don't let maintenance change code as that can get out of control and cause more issues. I let them view the code and force in certain routines for troubleshooting purposes but they can't make any changes.
Just my .2 cents

I dont know if this of any help but we currently use a piece of software called commander which basically acts as a server for all our software. All our PLC's are on a network which we can access wirelessly thoughout site.
When I want to work on machine I would book the present version out, do what I got to do then if there was any changes or modifications we comment within the software but also are able to comment within commander when we book it back in.
Everyone who has access to the PLC's have there own logons so can be tracked who's doing what. The other good part of it is that in the background of commander there will always be multiple versions of the software before any mods were made. (The only thing this is looked after our systems guys)
Hope this helps...
