Hello,

currently i am trying to establish a connection between my Sql Database and my S7-1500 with the Siemens Lsql library. When I try to enable connect the status turs to 7002 for a few seconds before it turns to 8602. I configured the plc and the database with the official documentation.

I can reach the database with telnet from an external device which makes me think that i configured the SQL Server correctly.

The problem seems to be at the PLC. I configured it like they did in the documentation but i have to be missing something.

Some things i already tried:

- Turning off the firewall

- Turn the Port in IPAll to 1433

- obviously enabled TCP

- created a user with sufficient permissions

- I disabled adhoc and changed len to 1023 in the static variables in the PLC program

I dont think it is a problem with the login information because i would get a different error.My PLC just doesnt seem to find the Database or does not want to establish a connection.

I hope you can help me. Thanks in advance.
