Error -65536 In LabVIEW Real-Time

Issue Details

When I try to run an example real-time VI or my own real-time code, I get error -65536. Why?


This error is usually related to a C-Series module and cRIO mode incompatibility. Try the following:
  • Reinsert the module and check connections.
  • If the chassis is in FPGA Interface programming mode, make sure you have opened an FPGA reference to a bitfile or FPGA VI with Scan Interface support for the module you are trying to access using the Scan Interface. 

Additional Information

If the module you are trying to use requires Scan Interface mode but your compactRIO target is in FPGA mode, refer to: How Can I Use Scan Engine and FPGA Simultaneously on a CompactRIO (Hybrid Mode)?
