provider.
Use the certificate by taking the following steps:
1. Save the certificate of your e-mail service provider in the file system of the engineering
station.
2. Import the certificate into your STEP 7 project with "Global security settings > Certificate
manager".
3. Use the imported certificate with every module that uses encrypted e-mails via the
"Certificate manager" table in the local "Security" parameter group.
For the procedure, refer to the section Handling certificates (Page 72).

value "3 (Error)" to ensure the reliable establishment of the communications connections.
