MAX error 7411 when downgrading cFP 2120

[geirove]

Hello,

I am running LV 8.2 for an old Industrial project that I am doing some changes to. The project is running on a cFP 2120. That cFP is running 24*7 in production.

The actual cFP 2120 I am trying to test my software on, currently has LV RT 2009 installed.

But I now need to downgrade it to LV RT 8.2.

I first tried using the MAX version (4.0.x) installed in LV 8.2, but when trying to do"Add/Remove" software, I get Error7411 as shown in link below:

I then tried to install MAX from my LV2009 distribution in the LV 8.2 environment. Installed fine, but when trying to run it, it complained that it was not properly installed.

I restored my PC, and tried to install MAX 4.4.1 from a LV 8.5.1 distribution. This version of MAX works fine, but I get the same Error 7411 when I try to click the "Add/remove"  software button.

So, the question is:

a) How do I clean the rt software (RT 2009) from the cFP2120 so that I can do a clean install of LV RT 8.2 onto it?

Please help, as all my searching has not given me any clue on how to do this !

Have you seen this?

Hello Muks

Yes, I have seen that. Upgraded to Max that came with LV 2009, that rendered MAX useless: It complained about a "faulty installation".

Restored XP computer, and tried with MAX that came with LV 8.5.1. That version of MAX worked, but I get the same problem.

Funny that National haven't thougt of this. There should be a way of "cleaning" software off a cFP so that one could start with blank sheets and install any LVRT version onto it !

Any help from National Instrument staff?

Hi

If you want to remove old software on a Real-Time controller you can format the device.

Hello,

I have a cFP 2210 with LV 2210 where I tried the technique in your link.

I did NOT get it to work.

I set the switch to Safe Mode, Powered off and held the Reset Switch on for at least 15 seconds on power on.

The cFP still had all its software intact. It was not formatted.

Hi

Have you tried to right click the FP controller in MAX and choose format? What happen when you tried this?

Hello,

I have already, in a roundabout way where I do not remember all the steps, managed to downgrade the cFP.

I think even selecting it in LV 8.2 MAX with 2009 RT installed on the cFP would produce an error.

I will try this again since I will later do more testing with LV 2009 vs LV 8.2 RT on the same controller.

I will get back with my experience.
