I'm trying to upgrade a series of durability test stands that have been running for several years. They are using LV 7.1 on cFP-2110 and cFP-22nn controllers, and I need to upgrade them since we've got into a Windows 7 development environment.
I re-wrote the I/O code in LV 2009 and installed it on a cFP-2210 and cFP 2200, and everything ran very slowly and died after 2 days of running. I then transposed it to LV 2011 and it has run perfectly for weeks.
Next, I tried installing it on one of the cFP-2110 controllers and found I could run it as source code, but not compiled. To solve that, I reduced the memory size of the LV11 FieldPoint installation by starting with the FieldPoint 6.0.10 minimal installation and then adding the components for Serial RT (they use RS232 terminal interfaces) and Shared Variable support. That worked and I ran compiled for a week with no trouble, rebooting power each morning.
After the weekend, it no longer boots up, and I get the same message on 2 cFP-2110 controllers when I try to deploy the compiled application on them.
"LabVIEW: VI is not loadable. In a built application, this error might occur because the VI being loaded was last compiled for a different OS, in which case you must save the VI on the current platform. This error might also occur if the VI is a polymor".
Below is the LV11 RT installation. Keep in mind that one of the controllers is a new installation and the other worked fine for a week. I know that the available memory is borderline compared to the 22nn controllers, and I wonder if a weeks worth of running may have reduced the available memory, although the program doesn't write anything to the RT memory. If I can't resolve this, it could be very costly for us to upgrade the quantity of 2110 controllers.
