Hi Chirstofer,
Thanks for the detailed responses. I would like to ask a couple of more
questions(which may be borderline naive or stupid :D ).
First thing that I would like to know- ignore my lack of knowledge on PLCs-
but from what I understand are devices which are small devices used to
execute
Hey Chris,
yes, this is definitive more complex then what I intended to do.
What I can suggest is that I prepare a PR for the following changes
1) Renaming Address to Query
2) Refactoring of S7 Driver to add
1) The new Parser
2) A "rich" S7Query which contains the S7Type a
Hi Julian,
Well we have one request, but this can contain multiple items each item has a

to read 1000 values.
And regarding the "Field" name ... the thing is

2) Adding Type and
