Why Does My Host FPGA FXP Read Write Control Node Cause an Error "Xnode Is Not Executable"?Primary Software: LabVIEW Modules>>FPGA ModulePrimary Software Version: 8.5 Primary Software Fixed Version: 8.5.1 Secondary Software: N/A
Problem: My Host FPGA Interface Read/Write Control Node is reading or writing to a fixed point control or indicator on my FPGA VI. However, my host VI has a broken run arrow. When I list the errors, the error says the Xnode is not Executable. When I double click this error, it jumps to my host FPGA Read/Write Control node that contains the fixed point data type. Why is this happening? Solution: This is a known issue when using LabVIEW 8.5 along with NI-RIO 2.4.x. This issue occurs with FXP data types in FPGA Interface Read/Write Control nodes because NI-RIO 2.4.x installs support for LabVIEW 8.5.1 that causes conflicts with Scripting Read/Write Control nodes using Fixed-Point Data Types. Upgrading to LabVIEW 8.5.1 and re-installing NI-RIO 2.4.x or later will fix this issue. Related Links: AE KB 4DPGKPKO: How Can I Transfer My Fixed-Point Data Using a FIFO or Memory in LabVIEW 8.5.x?
