Hi Cesar,
No they wouldn't. They would be exposed to the server implementation and the ui.
The thing is that the above structure s7 could probably automatically translate
into s7 addresses. However for Modbus an explicit mapping is required (sort of
mirroring reality with real plcs).
I was thi
Hi Christofer,
How would these data structures be exposed to the user? An API? Or a
service?
A simple way to see it would be to have the PLC data structures (DB, PEW,
M, etc.) as instances of ByteBuf from the Netty library.
Best regards,

Hi Tim,
I think the API must be at a very low level, bits, bytes, memory addresses.
This would allow everyone to customize their application.
For example, if my application were in the "mechatronics" area, a high
percentage of queries would only refer to peripheral addresses (bits,
bytes, words
Hi Chris,
thanks for picking up this discussion and for the three suggestions.
My initial approach would be rather similar to your suggestion 3 BUT with a
crucial addition.
My observation and belief is, that we currently focus nearly 100% on java (I

sorry for being late tot he party but I agree with whats been said and would

integrates nicely with Spring).

Hi Johan,
as Chris stated we had multiple discussions about "complex types" (e.g.
together with @Matthias Strljic).
But it would be good to describe a bit better what you exactly mean then we
should at least consider it for 0.6, I think.

Hi all,
what Tim describes is in the regular repo. We had to indroduce this "hack" as
we did not find any working documentation of the hex codes.
So I agree with you that it would be better to do it the "right" way but as we
needed these types we simply took the "easy" way.

Hi Chris,
Thanks for the warm welcome and your thoughts on the matter!
Like you said, both approaches can co-exist with one another,
therefore starting with the low-level approach is probably the
straightforward thing to do. My main initiator for the question was

I think I'll take your suggestions and start/continue with the plain
HTML/JS approach of option 1 as I already started and as the assets
are served from Spring Boot itself so integration into the build is
quite easy. If this gains traction I have
Hi Johan,
sorry for the late response ... it sort of managed to drop just outside the top

Let me double-check and summarize what I understood what you are asking for:
- You have some sort of "structure" you want to read in multiple locations
(memory blocks and PLCs)?
- You w

the Thrift project is currently voting on a new release … this will make the

So I’m hoping that anyone wanting to work on C++ that we will be able to

doesn’t work)

While implementing the S7Server part I noticed that my HelloPlc4x config is

not be enough to really play around.

Hi everyone again,
We're currently looking into creating a frontend for interacting with
the PLC Simulator, i.e. having an administration interface for
changing properties/input/output and, if time allows, some fancier

Hi everyone,
I'm currently working on creating a frontend and REST interface for
the PLC Simulator to control the different simulation modules for
testing and presentation purposes.
One question came up this morning with Chris about whether the backend
should be more low level or high level.

Hi Tim,
So depending on the TYPE constant used in the address (the actual String "enum

Is this in your PI fork, or is this in PLC4X main repo?

First of all it's a very good idea to simply the profile-stuff.
My thoughts to that are that we maybe could add a little shell-script

Hey
I extended the implementation because S7-1500 family returns a not known
datatype for those date-types, and there was a need to read those types. So I
acquire a set of bytes and extract the date information from that.
If that causes problems with the simulator we should have a deeper look in
Hi all,
as I have heard complaints that the current way we handle profiles is too

Currently if you just run “./mvnw install” it will only build the protocols.
This is probably not what the user wants.
