Hi Chris, Yeah, the OPC UA stack will be pretty heavy. Maybe not the raw package logic, but the complete feature set will be a bigger piece. So I assume it will take a while until OPC UA is mapped into a generated driver.
So I have a question how we will handle this in the larger version 0.6.0 we are aiming for? Matthias Matthias Strljic, M.Sc.

Hi Alvaro, well mixing old and new versions of Drivers and Runtime might be an issue. Julian would probably simply say: "Use our OSGI versions", but then I would respond with: "But we only have valid OSGi bundles for S7". I have to admit that I haven't had a look at any OPC-UA packets yet so I can't judge how long it would take to implement the port of OPC-UA with mspec. I would assume the protocol being very heavy so I would expect it to take a while. Modbus is probably the simplest of all, so I would assume this goes quickly.

Ok, once you start the porting to mspec for modbus, I could help in the testing of the results, and in general, reviewing the code. The protocols like OPC-UA which does not have a clear date for the porting, will continue working with the actual version, right?
