S7 DATA_BLOCKS and FLAGS_MARKERS error

Hey Everyone,
We are currently doing further tests regarding the Siemens S7 connector
(S7_1200) using the scrapper, and have come into an issue.

We testing different data types in DB (DATA_BLOCKS) memory area, most of
them are doing fine, but adding one of the following data types create an
error:
- LREAL
- CHAR
- TIME
- DATE
- TIME_OF_DAY
- DATE_AND_TIME

As soon as we add an item of this types there is a Connection-Alias error:
[image: image.png]

We also have to read values from the S7 "MERKER" memory area.
For that we use the plc4x Memory Areas *FLAGS_MARKERS *Code *M, *but
independently
from the used data type we also get the same error message.

We are using a 0.7.0-SNAPSHOT version, I have also tested with 0.7.0.

Is there something that still needs to be done? Any suggestions or comments
would be appreciated.

Best regards

Reiner Sommer

Und unfortunately you can't post images in these lists.
So could you please post the log output as text?

    Hi Rainer,

    first off all, the 0.7.0-SNAPSHOT version is older than the 0.7.0 … the newest would be 0..8.0-SNAPSHOT … so just as some side information.

    I can confirm, that not all types are fully supported. Mainly this is due to the fact, that not all of these types are supported on my S7-1200, which I used for reverse-engineering most of the S7 protocol.

    Having a check the following types might be problematic:

      *   LWORD
      *   LINT
      *   ULINT
      *   REAL
      *   LREAL
      *   WSTRING
      *   LTIME

    Also are there code collisions for:

      *   CHAR and STRING
      *   DATE, TIME_OF_DAY and DATE_AND_TIME

    We could highly appreciate some communication pcap captures of communication accessing these type of addresses to fill out some of the white sports.
