Ack CVI NC_FRMTYPE_ERR

[mekhatria]

Hi,

I have a big problem :

my project is to make a periodic frame (200 ms)  send it from cvi to the calculator (HS 500 M), und at the same time receive the calculator's frame, ok

but if the caculator is in reset mode (300 ms), i have to stop sending, until i receive any kind of frame frome the calculator,

so :

1) how can I  detecte tha calculator doesn't take care about the frames? (Akn .... or how)

I have used "NC_FRMTYPE_ERR"  to detecte any error on the bus, but I can't control the periodic frame (stop it until i receive a calulator's frame)

I have no better idea

so any suggestion !

thank you

Hi,

You could use the ncaction stop  function on your periodic written object to stop it if no frame comes from your device. You can restart this object then with ncaction start if your device is up and running again.

thanku Dirkw,

I have used ncAction , but i think stop und start are only used for CAN Network Interface not for CAN Object, in my application i use a CAn object to transmitte the periodic frame,

is there any other solution to stop und start the CAN object ? (if that http://forums.ni.com/ni/board/message?board.id=30&message.id=748&query.id=41774#M748     is realy so  ) 

thank again

Hi

yes you are right. We changed this with the latest driver 2.3.3 available on the web. Now you can use the ncaction to start your objects and now you can stop these objects again and restart them.
