5/04 frn 10

We just recieved a machine with a 5/04 and frn 10. when we try to go online or upload we get "proc corrupt". We are running linx 2.5 and logix 500 7.0. I can use data monitor in linx to look at the data files and it appears to be frn 10.

I am assuming we need to upgrade at least logix to 7.1 . We have many laptops so my next question is do we need to upgrade all laptops for program compatability. A handful of laptops are "global" and most are not mormally. I just want to be sure if a "global" laptop makes a change on any other proc that the "local" laptop will be able to use that program to get on-line.

What fun! RSLogix is backwards compatible, but not forward compatible. You can use the new program to monitor and edit old versions, but not vice versa. This is generally true of most software, because programmers have to eat, and their livlihood depends on selling the next latest-greatest version, even though it is a lot like the old one.

Virus-protection software is a great example. I suspect that there are fewer harmful computer viruses every year. Who has time to spend months developing new viruses? Years ago, when there was little security, any high school kid could do it, but not now. Yet we are told that we need ever more sophisticated protection. If that is true, then many of the anti-virus software programmers must go home at night and write virus programs! Who else would know the weak points? It kind of reminds me of the famous "Y2K" scare.

Lancie1, I have thought exactly this myself! it takes a lot of time

to develope viruses sophisticated enough to penetrate modern security, not to mention the reward/risk ratio of that endeavor. Three years ago I bought a professional version of an anti-virus program, which you could update yearly for a fee. Then a new version came out that was designed, of course, to replace this older version. They were only going to offer yearly fee renewals for a while, then you had to go to the next latest and greatest.

And (positioning tin foil correctly) who better knows virus
programs than the people who write the protection for them?

The SLC-5/0x firmware FRN10 has a lot of new functionality, which is supported by RSLogix 500 version 7.10. My favorite function in the new firmware is the DEM/CEM/EEM explicit message instruction, because I'm a network specialist.

That error code is RSLogix mis-interpreting the FRN10 firmware identification. Knowbase Answer ID 36179 documents this error code and confirms your assumption that RSLogix 500 v7.10 is needed.

Although there were some issues with backward compatibility in the early 1990's between APS v6 and APS v5, RSLogix 500 has full backward compatibility. You will be able to continue to use v7 or v6 or earlier versions of RSLogix 500 on your older CPU's, regardless of whether they've had programs edited or compiled by RSLogix 500 v7.10.
