You should really start from the beginning
I strongly suggest that if you do not have any experience with the ControlLogix (Or any of the Logix based processors)
You should go through the basic first. Many people made the mistake of assuming the ControlLogix has the same memory structures, ladder scan cycle, etc... as the PLC5/SLC500... but it is a totally different animal altogether.
For example...
... There will be a limitation on their "connections" to I/O modules, depending if it is an Analog, Diagnostic, optimized rack, etc.
... There is a feature in RSLinx that will optimized your OPC packets, and if you start editing the tags on line (e.g. changing from BIN to INT) You will probably get into trouble.
... It's best to use Arrays and the "User Defined Tags" to lower the comms between your PLC and MMI...
I can't list them all down, (Or even remember them all...) But there is a RSLinx/ControlLogix optimization tips document, that AB would suggest you read through... I don't think that reading through it is an option. I think you must look through it before you start you program. (I can't remember the document name. But the sales guy that serve you should know it... I hope))
