NI 9411 don't become 'ready' status

[cleska]

hi, all.

I'm a new to labview and fpga development.

I'm trying to get rotary encoder signals from NI 9411.

In VI, I put FPGA I/O method node to acknowledge that NI 9411 is ready, but the output from this node is False forever.

Of course, I supply 5V to NI 9411 and test it.

Also, maybe I install all I need to start NI 9411 (these are shown in this page(https://www.ni.com/ja-jp/support/documentation/compatibility/09/software-support-for-compactrio--com...)).

I'm glad if any advice comes.

other information

Controller: CompactRIO 9049(supply 15V)

Encoder: Maxon MR Type ML(I use it as two-phase(A and B))

if there is any information I should add, please tell me.

Hi, 

Could you share the details how the connections are done between the encoder and NI 9411?

Since you have mentioned about FPGA I/O method node to acknowledge the status of  NI 9411, perhaps you can refer to this link on wiring an encoder for the module.

You can also refer the FPGA I/O Method for more information

You can try to refer to this FPGA tutorial for your reference.

Hi, and thanks for your reply.

I'm sorry that I could self-solve this problem and forgot to make solution of this question.

In my system, I set C-module NI 9411 in fpga controller as 'NI-DAQ real time scan mode'.

I change it into 'FPGA mode' and my system worked correctly.

Below, I write down other thing I did.

・Uninstall NI DAQmx tools

Again thanks for your attention.

I'm glad if it helps someone.
