im interested in as going to work within open source project team and it's
not for fun only. i will choose first.

it's a typical , don't care

i think the system must contain a tcp/ip stack,also take a focus onto
DeviceNet, Profibus, CIA, well ancient modbus still in use.
existing tcp/ip will reduce some pain with industrial protos support,u may
take a google to learn more.
here

an overview of profinet.

??  "it has all functionality for us" - explain please.

superish security for plc-like devices is a marketing bullshit. DAC is
needed to cover the ass ;)

how can i help now ? // "in the team" ;)
