Kplex can manage this when it is setup correctly.
On kplex page you can select any device. A click on diagnostic will show which sentence get in and which get out.
You can directly reduce traffic if you filter (block) input sentences.( typical when there are more than one GPS).
The output diagnostic does show how much bandwidth your data needs. You can reduce this with filter settings.
New in openplotter 1.2 is that you can filter system and signalk.
For low speed communication (4800) use "Accept only sentences:" otherwise you will flood your device.
You typically create loops when you have systems as opencpn which get all available sentences!
If opencpn (or any other chartplotter with nmea0183) creates a RMB sentence for the autopilot and sends it to kplex this sentence is available for all. And that means it will be send back to opencpn. It is part of the input stream to opencpn.
That's the loop. You can block it if you create another output device which has the filter Ignore sentences RMB.
Another typical loop is if you create nmea0183 sentences from Signal K or and they went from kplex into signalk to nmea0183->signalk converter. You can easilly add an ignore filter for these sentences.
In other words: Every device which uses input and output invites you to create loops.
