TCON with the tags of the data type TCON_IP_V4_SEC.
Settings at the TLS server
To set up a secure TCP connection in the TLS server, follow these steps:
1. Create a global data block in the project tree.
2. Define a tag of the data type TCON_IP_4_SEC in the global data block.
The example below shows the global data block "Data_block_1" in which the tag "SEC
connection 1 TLS-Server" of the data type TCON_IP_V4_SEC is defined.
The interface ID has the value of the HW identifier of the IE interface of the local CP (TLS
server).

3. Set the connection parameters of the TCP connection in the "Start value" column. For
example, enter the IPv4 address of the TLS client for "RemoteAddress".
