Error 65536 In LabVIEW Real-Time

Issue Details

Solution

C-Series module and cRIO mode incompatibility

• 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.
• 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)?

C-Series module and Slot configuration incompatibility

• This error message can appear when a slot in a CompactRIO (cRIO) chassis is configured for a module other than the module currently inserted in the slot. This usually happens when a module that takes a long time to power on is inserted in a slot configured for a fast module.
  • Add a delay of a couple of seconds to the start of the FPGA VI to give the I/O node enough time to detect the module properly. If after doing this you receive an incorrect module error/warning, either reinsert the modules in the correct locations or appropriately change the I/O module setup in the FPGA Project.
