Configure all security parameters via the web server. In the Address field of your
web browser, enter the IP address that displays on the front of the module.
'The 1756-EN2TSC module has an embedded HTTPS server that it uses to
provide secure web communication. An HTTPS server uses a certificate so that
the client can verify server authenticity. For web sites connected to the Internet,
certificates are normally signed by a trusted certificate authority. Web browsers
are then able to verify the authenticity of the web server by virtue of its certificate.
The module comes with a self-signed certificate because the module is not
directly connections to the Internet. Self-signed certificates are not signed by a
known, trusted authority, so they must explicitly be accepted by the user when
connecting via the web browser.
Initial Powerup On initial powerup, the module generates a new certificate for the embedded
HTTPS server. This can take up to several minutes. During this process, the
message ‘SSL certificate generation in progress’ is shown on the module display.
Wait until the module is fully booted and ‘OK’ is shown on the display before
accessing the module by using a web browser.

IMPORTANT When you enter the IP address, you must enter the prefix https:// in the
address. If you enter an http:// prefix, the module redirects to the
https:// prefix.
