Hello,
I have two stations running RTnet, one as a master and one as a slave. I want
to measure the time, which a message, sent from master to slave, takes. But,
I don't want the time of the transmission only, but the complete time of all
software layers this data is processed through.
_______________ _______________
| A | | D |
|______________| |______________|
| B | | C |
|______________| |______________|
| RTnet (Master) | | RTnet (Slave) |
|______________| |______________|
| |
|______________|
So, I create the data, that should be send, in Layer A (Master) and send it
over RTnet to Layer D (Slave).
I want to take the time when the data leaves A and when it arrives D with
rtdm_clock_read(). If I have the offset between master and slave, I can
calculate the time it took to pass A, B, both RTnet stacks, C and D.
As RTnet keeps track of the offset in it's stack, I want to use this value. Is
it possible via the API? I didn't found anything. Or do I have to manipulate
the stack to pass the offset to the higher layers (C and D)?
Thanks and have a good time!
Karl
