Hi Chris,


thanks for the clarification, as you see I've never been that deeply involved 
with an apache project, yet (up to now just small fixes and commits).

And in that case I agree with you to keep "conceptual" discussions here.



Best

Julian

    Hi all,

    

    Well the thing is, that if we take discussions to the issue, people on the 
list aren't included in this. So if there are usage aspects, they should be 
discussed here, I think. Otherwise we would require folks to automatically 
monitor other sources too. However I'm fine with implementation details being 
discussed there.

    

    After all, the Apache mantra is: "if it didn't happen on the list, it 
didn't happen"

    Hi all,

    

    

    

    as it seems like everybody agreed on the proposed API Change / extension I 
allowed myself to create an Issue for this to coordinate the work on that under 
https://issues.apache.org/jira/projects/PLC4X/issues/PLC4X-43

    

    I suggest that we move further discussion there.

    

    

    

    Is this okay for all of you?

        Hi,

    

    

    

    

    

    

    

        Looks good to me.

            Hi Julian,

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

            well I would propose to add the type suffix with ":{typename}" but 
unfortunately every system has its own types and interpretations.

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

            So our current S7 address would look like this:

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

            DATA_BLOCKS/1/0 --[would be changed to]--> DATA_BLOCKS/1/0:INT

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

            One universal notation for addresses in all drivers will probably 
not work. For example with Modbus the memory block (Coils or Registers) for 
example determins the datatype and with Ethernet/IP for example the address 
will probably look more like:

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

            #2#1#5:INT

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

            Which means:

    

    

    

    

    

    

    

            #{classId}#{instanceId}#{propertyId}:{type}

                I guess I'm fine with everything but perhaps we should try to 
find a syntax which goes well for all drivers where this feature is needed.

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

                Could you post an example string for such a suffix?

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

                And I'm definetly for a "guessing" feature to keep support for 
the current API.

                    And regarding Sebastian's suggestion to keep the "it 
friendly" format. I think this shouldn't be a problem.

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

                    All we need are more pattern matchers. What we do need 
however is an extension of the existing format to add the type ...

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

                    Not quite sure if we should prefix the existing strings 
with a type or add them with a suffix.

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

                    I think I would prefer a suffix ... If we make it a suffix, 
we could make it optional and guess a fitting default type if omitted (same 
behavior as now)+
