Is there a definitive specification document for the SAP network protocol / SQLCLI used to communicate (command line) with a MaxDB database? Our aim is to directly UPDATE table data from a networked device such as am Allen Bradley or Siemens S7 1200 PLC running on the customeru2019s manufacturing plant. Note that a PLC does not run Windows etc. and therefore cannot use ODBC, OPC or any other driver. There are snippets of information on the Web but none fully explain the TCP packets as seen using Wireshark for queries such as u201Cupdate tablename set column=255u201D. Thatu2019s all we want to do!
(We can already do this with an Allen Bradley Rockwell CompactLogix PLC and a MySQL database.)
Regards,
No, we do not have a definitive specification document for the current MaxDB versions.
If anyhow possible, try using JDBC.
Other than that, you could search the web for 'MaxDB' and 'xorder7'. This should show a specification Word doc of about 150 pages. Not sure if that really helps, though...
