This goes back a ways. 6200 is DOS based and created a lot of files. If you are looking at only the ladder logic, I think you should be able to upload from the processor with either package. If you are hoping to bring in the descriptions. There is not much you can do here. 6200 was weak in the descriptions and realy required an addition program called Taylor Document. If you could find someone that still has a copy ICOM, the beginning of RSLogix, it may allow you to do this in 3 steps. 6200 to ICOM then ICOM to RSLogix. IF not, looks like a lot of keyboard time. I am sorry I could not be of any real help, and alot of this is from memory but has been 12 to 14 years sense I used this.
