Hi everyone.
I have been pondering on an idea put forward about the problem of proprietry busses (modbus, profibus, devicenet et. etc.) . Someone mentioned that to truly have an open source bus, we would have to create our own linux plc bus.
So I wrote some code to see if the idea was plausable. (its a bit scrappy at the moment but thats another story).
May I put this proposal to the linux PLC debate.
If we create an open puffinbus and imbed its code into the linuxPLC and not have any other bus protocol included in the code then the linuxPLC is kept small and well sort of standard. It is then up to the external bus types around to provide a bus filter/converter to drive their proprietry busses. This should keep some of the politics away from using proprietry stuff and it allows us to argue for years about which way to improve our own protocol.
O.K. the filter/converter may impose delays in updates etc. but this may encorage people to use the puffinbus as their standard bus instead of all the other ones.
If you wan't a better idea of what I'm trying to propose, just let me know and I'll put together a little prelim spec.
regards
Phil
P.S. Its only an idea at this stage so don't flame me yet.
