Possible Studio 3 compiler bug

On last Friday, I had to do a remote load change in one of my projects and suddenly my Autopatch Precis 18x18 Duet module wouldn't work anymore. The project has a NI-3100 with Duet firmware v3_30_371. After multiple remote Master reboots, I had to drive to the client's house to troubleshoot the system. After a couple hours of reloading, rebooting, resetting the Autopatch, studying the code, which run fine for a year and a half, I decided to update the NI firmware to the latest v3_41_422 version. After the normal Master reboot, the Autopatch code started working again. So, I think that Studio 3 new compiler may also require the latest Master firmware to run smoothly. So be aware of this when using Netlinx Studio 3.

    That's normal, actually. You always have to update Duet firmware to match the compiler version.

    I came across a similar issue yesterday on my test bench. Code that writes XML files using variable_to_xml() was not behaving on an NI-700 with v3.14.xx firmware, but was working fine on my NI-3100 with v3.41.422 firmware. Updating the NI-700 to v3.41.422 fixed the issue.

    For the curious, the symptoms were lots of question marks (?) in the XML where one would normally expect both values and identifiers. My variable was a structure which had a few devchans in it.
