Trying to do it serially? Have you tried DH+ with RSLinx? Super simple download to the P.V. ALSO remember, if you are using DH+, that the default speed is 57K. If the old P.V. was a different speed that would give you a hassle. Oops, I just re-read your topic. The firmware versions an everything are going to be so very different. You are going to have to run the P.V. file with Panebuilder and change the version number. That is a huge leap from 1995 till now.
