Disabling of cRio NI 9012 working incase of TCP filure???

[Shoaib Akhtar]

Hi,

I am working on cRIO NI 9012 and NI 9505 card for motor control.I want that motor and cRIO should stop working in case of TCP/IP connection failure(Cable unplugged or connection failure).But when i unplug the TCP cable from cRIO the connection with cRIO fails but it keeps on working with initially burned program parameters and motor keeps on running.

PLease help me out in this matter.

Thanking in advence.

Best Regards,

Shoaib

Hello Shoaib,

I believe you are looking to implement a Watchdog on your Real-Time controller. Below I have posted a link to information on the 'Configure Watchdog.vi.' These links should serve as a starting point for working with watchdogs in LabVIEW. The premise of a watchdog is a continuous tineout monitor implemented each iteration; such that, if the watchdog is not 'whacked' (i.e. triggered) the watchdog will invoke a system stop, reset, etc. The event invoked by the watchdog timeout is user programmable.

 Hope this helps assist in your project deployment.

Cheers!
