I’ve used the Keyspan USA-19HS on SLC’s and CLX/CPX just fine.

A very big T H A N K Y O U to Geniusintraining (plccable.com) for having the two cables I needed, got them to me overnight, and I am now riding the dinosaur.
Depending on how the code is written, you may consider uploading the DM area as well. Values may exist in the DM areas you would need to understand the program, they can also be used to set up special I/O units.
They do not upload when you upload the ladder.
Hope this helps
What modules are in the system?
That will tell us a lot.

I would suggest upgrading the system. Easy upgrade!
the C200HX CPU can be upgraded to CS1G (Pick from several CPU's)
Same power supply
New rack (the one that can use C200H cards and CS1 cards)
Same I/O cards. (special I/O cards get tricky as their address's may change)
If I remember correctly, CXP (Omron PLC programing software, part of CX1)
can be used to "Convert" the old program to work with the CS1G CPU.
As GT Support said, the I/O cards will tell alot about this system.
If it has a motion card, certain data and maybe a program will also exist in the cards memory. (Another upload)
Regarding uploading all memory areas, including the DM area (Data Memory):
With your brief overview of the system, say a Yaskawa (moving the AGV) goes to position #1.
Position #1 is a fixed distance from the origin and never changes. A lazy programer could load the value of position #1 into DMxxxx. (the value could be in encoder pulses, or scaled) The program would than tell the Yaskawa, Mov to position stored in DMxxxx. (Just uploading the ladder, you would never see the position #1 value)
Hope this helps.
(Just uploading the ladder, you would never see the position #1 value)
I would still upload the DM area.
