RE: Scan Engine : Can't switch to active mode

[j3r3mi]

Hi all, i'm using NI 9074 which was configured to be in active mode. 

But when i view it in System Manager, its showing "Configuration" mode.

So i went a step further, to programatically set it to active mode using "Set Scan Engine Mode.vi" but to no avail. The error codes are show below.

The errors in "Array" are  the returns from reading IO variable"

"error out" shows the error code returned from setting the scan mode.

Warning 66030 occurred at Read Variable in main.vi

Possible reason(s):

LabVIEW:  This I/O variable is referencing an I/O device or channel that is not active in the current I/O mode.  Data read may be stale or invalid and data written may not be sent to the output.

Warning 66030 occurred at Read Variable in main.vi

LabVIEW:  This I/O variable is referencing an I/O device or channel that is not active in the current I/O mode.  Data read may be stale or invalid and data written may not be sent to the output.

Error -2132869110 occurred at Property Node (arg 1) in Set Scan Engine Mode.vi->main.vi

Possible reason(s):

LabVIEW:  (Hex 0x80DF000A) There was a communication error between the host and target.

The above error shouldn't happen as i could see the cRIO from MAX and System Manager and i used the default values on "Set Scan Mode.vi" which is "localhost"

Does anyone have the same problem as me?

Did i done something wrong or i missed out something?

BTW, i have a 9144 (Expansion chasis) connected to my 9074, how can i check the status of 9144, eg connectivity.

MANY MANY THANKS! 😄

Most likely it is your code that's causing the engine to stay in config mode. Can you post your VI so I can look it over?

Hi, I have same problem with EtherCAT communication.

If you got solution of this problem, plz share it 🙂

I think disconnection with EtherCAT slave cause this problem. 

Plz check this out.
