You can monitor the FPGA die temperature of the NI PCIe-1477 using an FPGA I/O Node. After adding an FPGA I/O Node to the block diagram, click the element section of the node, and select FPGA Temperature (C). The FPGA device may malfunction at temperatures over 95 °C. If the device measures greater than or equal to 95 °C, stop the FPGA application and consider moving the device to a more suitable environment.
