send remote frames periodicaly

[c-air]

Hello.

We are French students and we are designing a Bus Can application
with NI-Can in order to dialog with a Sodemo Ev9 calculator.

With have decided to send periodicaly remote frames in order to
catch the desired datas with the vi ncConfigCANObj.vi and the readCANObj. But we
have a problem; with a scop we can obseve that the remote frames are not send periodicaly every
100ms but they are send wtih no delay.


Have you ever seen this problem, and can you help us.

Thanks.
bye.

Hello c-air,

what 'Communication Type' do you use in your CAN Object configuration? Usually, I would use the 'Receive Periodic Using Remote' type. It periodically transmits a remote request and copies the response (a data frame) into the receive buffer.
However, the object stops the periodic transmission, if there is no response (no data frame). So you can't generate a constant stream of periodic remote frames, if no one responds to them.
