  1. Had a great success with Network Published Shared Variables from the get-go. Used them on a large project sharing data between multiple devices on the network - worked great. Until one day (yesterday), when they stopped. No change in the code, the same base was running for 4 years on multiple systems (NI-9042 cRIO + NI-9147 eRIO). Yesterday, loaded the code on a brand new cRIO and ooh-la-la - surprise. No more data sharing. Only on a new platform. Loaded the same code on the old one - everything works. Modified the code to make data sharing more transparent for troubleshooting. No, there is no data coming to the consumers. Not sure though whether it is writing to the shared variable or reading from it but the fact is no more data. At this point I am totally baffled to what could possibly happen. Checked the drivers - the Network Variable Engine 17.0 is installed. Although, I am not sure how to check if it is running. I tried to use Linux tools in CLI but didn't see any process name resembling the Network Variables Engine. I wonder if anybody had similar experience or can suggest where to look? Maybe I am overlooking some weird settings somewhere? Like blocked ports or network registration... However, I couldn't find anything, no matter how hard I looked. Any help would be greatly appreciated! Thanks.
