Crio 9401

[bull09]

Dear,

            I have some problems when I use the Crio module 9201, as a digital input!! I don’t know the reason why me program only reads the input in the first scan of the FPGA.

I use an indicator in the front panel, for knowing the behavior of the input but, its indicator it never changes during the running operation. If during the download I have a High TTL level in the physical input, then the indicator becomes green, but if during the download I have Low TTL level, then the indicator becomes red. Then after download operating when the FPGA is running the indicator never changes, as the input was high or low the indicator always maintain the initial value.

            I don’t know what happened!!! Everybody know something related to this problem.

Best regards,

Hi,

Can you post the FPGA VI and LV Project that you are using?

I'm assuming you are reading the channel from a loop. Have you tried connecting the loop terminal to a numeric indicator to make sure the loop is running? Could it be that an error is being wired into the IO Node which is causing it to not execute (no-op)?

Hi,

First of all, apologies me for my reply delay.

Although, I solved the problem 2 minutes after that I post the message .

The problems was that I need to run the FPGA VI first and then run the RT-Module VI. I thought that if I run only the RT-Module VI, the FPGA starting to run too, but it not.

JMota Thanks a lot for your message.
