No! No! No! No! No!
Argh, now I have to leap into the abyss!!
Do not upgrade from RSLogix 5000 v20.01 to v20.
03!
Go straight from RSLogix 5000 v20.01 to v20.
04!
Right, as concisely as I can...
RSLogix 5000 v20.03 is a "Product Resiliency Release". What does that mean?...
This Product Resiliency Release includes security related features such as tamper prevention and detection; intellectual property management and source protection; and user authentication and authorization.
All nice, but what does it mean for you?...
Offline:
If you create a v20.03 project then only users with v20.03 software can open the project offline (or v20.04). You may have more than one person or workstation with v20.01 currently in use. Anyone else with v20.01 software cannot open your v20.03 project. If you attempt to open an existing v20.01 project using v20.03, then it will prompt you to convert it to v20.03. It too can now only be opened by v20.03 software (or v20.04).
Online:
If you have existing controllers running v20.01 projects, and you upgrade to v20.03 software, then v20.03 can upload the project from a v20.01 controller but it cannot go online. You would have to convert the v20.01 project to v20.03 and download again into the controller. Users with v20.01 now cannot go online with these controllers.
This is all fine if you are just doing your own v20 project work and all your current v20.01 projects can, and will, be converted to v20.03 and downloaded again. And also, all users who must interact with the converted projects and controllers will also be running v20.03 (or v20.04). If not, then you may find at a later date that you, or another, suddenly cannot go online to one of your previous v20 controllers.
RSLogix 5000 v20.04 minor release was introduced to restore minor compatibility between all v20 projects and controllers. Most programmers will be using v20.04 by now.
You cannot install and run RSLogix 5000 v20 minor releases simultaneously on the same workstation PC. It must be v20.01 or v20.03 or v20.04.
Again, and in keeping with the good general advise we were attempting to give you, please upgrade to the latest, highest, minor release of RSLogix 5000 v20.04, and avoid any or all of the above potential headaches.
