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.

Chris

Betreff: 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:
[cid:ii_karwzil70]

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
