Issue Details

I receive the following error when deploying a CompactRIO project using the NI 951x in slots 5-8.  

Figure 1. Conflict error

This module cannot be deployed to this slot in Scan Interface programming mode. Only the first 4 slots have the high-speed interface support that this module requires. You can resolve this issue either by relocating the module to a slot supported in Scan Interface programming mode, or by using LabVIEW FPGA programming mode instead.

Solution

The NI 951x drive interface modules must be connected to CompactRIO slots that support high speed interface (HSI).

Additional Information

  • By default older CompactRIO chassis, such as cRIO-9072, 9073, and 9074, only support HSI on four slots due to the available FPGA resources. By default these are slots 1-4.
  • If you are not programming the FPGA, the bitfile you create will be blank. This should still be loaded to the FPGA upon system startup using the initialization process described in Correcting SoftMotion Scan Engine Errors -2147138411 and -77055
