Reset
In the "Reset" area, you can reset the communication module to the factory settings. When
you reset the communication module, all set configuration data, settings of the user
management and address information are lost.
To reset the communication module to the factory settings, click the "Reset" button. After the
reset, the communication module is automatically restarted. Note that, after this, you need to
assign a new IP address to the communication module.
If you lose your administrator password, you must reset the communication module to the
factory settings as described in the section "Restoring the factory settings manually
(Page 173)".
IP address
In the "IP address" area, you can change the IP address, subnet mask, and gateway of the
communication module. As an alternative, the IP address can be obtained from a DHCP
server.
Note
Support of option "12"
When the address is assigned via DHCP, the option "12" (hostname) is also supported. The
host name can be taken from the SNMP variable "sysName".
The variable can be written using SNMP tools.
HTTPS certificate
In the "HTTPS certificate" area, you can transfer certificate files and certificate key files to
the communication module. Remember that you first need to import the data into the
communication module before you can activate it.
Using the certificates, you can integrate the communication module in your specific security
infrastructure. Certificates are used to check the identity of a person or a device, to
authenticate a service or to encrypt files. You can create your own certificates or use official
certificates created by a certification authority. You can import certificates that contain a
certificate as well as a private key (PKCS#12). When you import certificates and the
associated private keys in separate files, then both files must be coded either in "ASN.1" or
"Base64".
You can use 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.
Contact your administrative IT department for further information on the topic of certificates.
Device description files
The GSDML and ESD files current at the time of delivery as well as the OPC UA device
description file are stored on the communication module. Click the "Save on PC" button to
transfer device description files to the connected PC. You can use these files to integrate the
communication modules into the configuration software of your S7 and Rockwell controllers.
