PCIE7852与SCB-68连接,SCB-68的接线口要如何接线才能通过LABVIEW FPGA控制模拟信号的输入输出?

PCIE7852与SCB-68连接,SCB-68的接线口要如何接线才能通过LABVIEW FPGA控制模拟信号的输入输出?能否提供比较详细的接线图和代码示例图?我用的是R系列多功能RIO设备驱动。以上实际包含了两个问题,时间略紧,请求各路大神指导一下,谢谢!

SCB-68A is a terminal block. You need a SHC68-68-RMIO and SHC68-68-RDIO to connect the module and the terminal block.

已经使用SHC68-68-RMIO连接,但AI0无法采集到数据并测量AI0没有电压,SCB-68A使用直通模式

Can you attach the program you used to measure the AI? 

Besides, what signal did you connect to AI0? NI does not specify what voltage a device will read when there is no signal connected. (Incorrect Readings on Unconnected or Open Channels of DAQ Device)

AI0的连接信号是模拟信号,现在AI0测量有电压但是上位机采集不到信号

The connection signal of AI0 is an analog signal. Now AI0 measures voltage but the host computer cannot collect the signal.


You mentioned that your host computer cannot read any signal but you only shared the block diagram of FPGA VI. Please upload the entire LabVIEW project including FPGA VI and host VI.
