jframe input polling question

Zach 4 years ago in IQANdesign • updated by Gustav Widén (System support) 4 years ago 1
On some machines I have a polling request set for every 500ms.
I wondered how often polling happens by default if I don't use the polling request.

Sometimes I have polling for engine hours, battery voltage, and fuel used.
Sometimes I don't.
I would like to know what to consider for determining when I should.
J1939 is configured for 250kbs.
I have 2 second timeouts.
I thought that the protocol went through each pgn to see if there was information to be exchanged, then it got the information from each pgn.
So if my timeout is 2 seconds, then I would think polling every 500ms would not be something worth doing.

IQANdesign 4.03.26 withdrawn

A problem with the recently released IQANdesign 4.03.26 was discovered earlier today. The problem occurs with systems that includes one or more XA2 modules, where these modules may not be initialized correctly. We have decided to withdraw this release till the problem has been corrected.

If you have already upgraded, please switch back to 4.02.16.
