First time - need Contrologix 5000 info
(OP)
Hello,
This is my first post, so please be patient.
I am an experienced PLC-3, PLC-5, and SLC programmer, but I am trying to learn Contrologix 5000 and am having some difficulty with the data structure. I am trying to teach myself, but I'm using a working processor and must be extremely careful.
Will someone point me to info concerning data tags, alias, style and other data type info for the Contrologix 5000? I have read the Allen-Bradley quick start guide and it does not offer much discussion of the data formats.
Thanks for your consideration, and I look forward to being a part of this forum.

You can find it on the Rockwell manuals web site:

Welcome and good luck.

The ControlLogix does not have data files like the SLC or PLC (or most other PLCs for that matter). Rather you declare tags (variables). If you have ever programmed in C or Pascal or similiar language, this should be familiar.
Aliases are tags (or rather tag names) that point to a different tag called a base tag. So you have a single piece of data refered to by two different tags or name.
Another important feature is user defined data types. These are very similiar to structures in C.

I'm not sure, but do you think these type tags were created to interface with RSView32?
RE: First time - need Contrologix 5000 info
I have done a few of these myself, where it is important to retain some of the familiarity of the PLC-5 program, as a transition is made to ControlLogix, especially if you have numerous installed applications being serviced by field technicians.

thanks for the reply.
RE: First time - need Contrologix 5000 info
There are some application notes in the Rockwell Automation Knowledgebase which may help you.
Go to:

and use A5550 as the keyword.
RE: First time - need Contrologix 5000 info
Wow, thanks for the info, I searched on A5550 and got info that was very pertinent to what I am looking for.
What else do you know?
