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 59: Mode 1 – Customer Root Certificate does not exist
Mode 2 (see Section
• 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
