RemoteFrames

[franc444]

Hi,
In the example of majorNetwork in its omnetpp.ini file, there is a source app that sends remote frames but I am not sure which node will receive this?
it is stated as:

**.Infotainment_nodes[0].sourceApp[0].idRemoteFrames = "2"

so the sending node is Infotainment_nodes[0] but there is no receiving node, right?

Hi,
yes there is no destination node configured to consume this frame. But it gets forwarded from the Infotainment bus to the Antrieb bus. Therefore gateway2 is configured to receive the frame.
Hope this helps.

Thanks @Musteblume
I can see that gateway1 is also configured to receive the frame as it might be consumed by one of the Antrieb nodes. I would like to understand more how the node will be configured to consume this remote frame?

Hi again,
my previous answer was not completely correct.

The remote frame is requesting id 2 and should therefore be consumed by Antrieb_nodes[0].sourceApp[0] which then sends a data frame with id 2. For a small example of this look into FiCo4OMNeT->examples->can->multipleSourceApps.

In case of the SignalsAndGateways->majorNetwork example there is a miscofiguration in gatway 1. It receives the ethernet frame (ctID 30) containing the remote frame id 2 but send it back to the network and not to the bus.

I will have a look what the cause of this misconfiguration is.

Hi,
i have fixed the problem. The fix will be released here with the next nightly. This are all the changes (in gatway1.ini):

...
33  **.gateway1.tte[0].TTvlinks[2].destination_gates = "gatewayApp.TTin"
...
42  **.gateway1.tte[0].TTvlinks[3].destination_gates = "phy[0].TTin"
...
49  **.gateway1.tte[0].phy[0].shaper.tt_buffers = "TTvlinks[0], TTvlinks[3]"

Best regards

Thanks for the fix.
I am still not sure which node will receive the remote frame? should not be consumed eventually by a sinkApp? in the multipleSourceApps example the remote frames are being transmitted between two nodes right? but the sinkApps do not record the statistics for the remote frame i.e. rxRF they only record for rxDF.
Am I missing something here or there is an issue with the statistics recording?

Hi,
currently you can have one of two configs:

1. A traffic source with the same id which gets triggered by the remote frame. The source has no rxRF statistc
2. A traffic sink consuming the id and record the statistic

You could add rxRF to the source or change the canNodePort to allow both configs simultanously.
