The "System - Device settings" menu item

In the "System - Device settings" menu item, you can update firmware, reset the
communications module to the factory settings, change the IP address of the
communications module, load certificates on the communications module and transfer
control files to the PC.
This page is divided into the following areas:
• Firmware update
• Reset
• Device description files

Description
In this area, you can transfer certificate files to the communications module.
Valid formats:
• *.p12, *.pfx
Binary file format, in which the certificate file and the certificate key file are
stored in a single file. This file is usually protected by a password. Enter the
password in the text box at the bottom. Note that this format can only be
used for server certificates.
• *.cer, *.crt, *.der, *.pem
Binary or text coded file format, in which the certificate file and the
certificate key file are stored in separate files. Note that the server
certificates necessarily require a separate certificate key file. For client
certificates, CA certificates and issuer certificates, only the certificate file is
specified. The certificate file and the certificate key file can be either binary
or text coded.
• *.crl
Binary or text coded file format for blacklist files. These blacklists are
necessarily required for CA certificates and issuer certificates. In this case,
select the certificate file and the blacklist file before you click on the
"Import" button. If a matching blacklist has already been stored on the
communications module, a CA certificate or issuer certificate can be
transferred by itself.
Note that only files with the file extension *.crl can be used for blacklists.
Once you have imported a server certificate, you still need to enable it.
Button to create a certificate signing request.
This area is only displayed when the certificate types "Server certificates" is
selected.
Click the "Create CSR" button to create a certificate signing request (CSR). The
CSR file contains all relevant information of the installed server certificate. A CA
(Certificate Authority) can create a signed, module-specific server certificate
using this file that you can then import into this module.
