Detecting C Series Module Fault through I/O Variable Node

[e.ono]

Hello LabVIEW Users.

My name is Eisuke Ono, An Application Engineer at NI Japan.

One of our customer is requesting a function.

The function is to retrieve information of module fault from C Series I/O variable Node (Scan Interface).

I know that we can get the information of module fault through FPGA I/O node, but not through Scan Inteface mode.

The customer's application is embedded condition monitoring system. It runs 24/7.

So it is very convenient if he get information of module fault C Series I/O variable Node Error Output.

I agree his opinion.

What do you think?

Bestr regards.

Can you provide a little more detail?  I'm not exactly sure what you mean.

• What module are we talking about?
• What error code are you getting from the FPGA I/O node that you'd like to see an equivalent of from the IOV node?
• Maybe you can attach some example code to show what you mean?

Hi RossH!

Can you provide a little more detail?  I'm not exactly sure what you mean.

• What module are we talking about? >> Any module.
• What error code are you getting from the FPGA I/O node that you'd like to see an equivalent of from the IOV node? Error 65556 for FPGA, −65536 for RT IOV. I found that we can identify the communcition loss is detectable.
• Maybe you can attach some example code to show what you mean?

Yes. I will attach codes.

I misunderstood the error codes.

Is it possible to detect module fault other than communication error through IO node (IOV or FPGA node)?

The goal is to detect Module Fault (Other than Communication Error) through IOV or FPGA node.

If it is already implemented, I would delete this thread.

Best!
