Two modes exist for safe data links.
Mode 1:
No examination of the server certificate takes place when setting up the connection.  The
authenticity of the server certificate is not verified. See 
Figure 54:  Mode 1 – Customer Root Certificate does not exist
Mode 2 (see 
1. Step):
Customer Root Certificate is inside of the module.
Command: Switch on Certificate Verification for HTTPS Connections was sent.
The server certificate is examined when setting up a connection. Two configurations are
valid. The server certificate is identical to the certificate in the module (both certificates are
self signed root certificates) or the server certificate forms a chain with the certificate of the
module. Thus the authenticity of the server certificate can be examined with the help of the
certificate of the module. See 
Figure 55:  Mode 2 - Server Certificate and Certificate into module are identical
