There are several J1939 PGNs that are transmitted at 10s intervals, which exceed the built in invalid data timer of the PV750. Is there a workaround for this?

Below are some examples:
PGN 65279
PGN 65268
PGN 64977
PGN 64980

I would suggest adding a column to the J1939 database page that allows the user to set the timout for each PGN.

Adjustable time outs have been requested in the past, and is being considered for future releases.

It definitively would be better to be able to set the timeout individually as suggested by Mbowdich. But should it not be by default a multiple of the frequency? This would eliminate the issue listed here.
For the current version, what is the timeout value and is it adjustable? Is the status of a variable (valid or not) accessible in programming?

We have a 2.3 release towards the end of 1st Qtr 2011. Will try to have this feature in by then.

In the meantime, here's the other info you're asking for.
- Current timeout is 5seconds on all modbus, 1939, and CANopen parameters
- You can control the timeout in scripting of other variable. In 2.1, we give you the option to do a write with timeout from scripting (see scripting guide viewtopic.php?f=5&t=37&start=0 Section 7.4). Obviously it's not the ideal solution that you've suggested, but it can help alleviate problems till then.

Thanks for the input!
