Proline Promag W 500
10 Endress+Hauser
The device can communicate with OPC UA clients using the "OPC UA Server" application package.
The OPC UA server integrated in the device can be accessed via the WLAN access point using the
WLAN interface - which can be ordered as an optional extra - or the service interface (CDI- RJ45) via
Ethernet network. Access rights and authorization as per separate configuration.
The following Security Modes are supported as per the OPC UA Specification (IEC 62541):
• None
• Basic128Rsa15 – signed
• Basic128Rsa15 – signed and encrypted
Access via service interface (CDI-RJ45)
The device can be connected to a network via the service interface (CDI-RJ45). Device-specific
functions guarantee the secure operation of the device in a network.
The use of relevant industrial standards and guidelines that have been defined by national and
international safety committees, such as IEC/ISA62443 or the IEEE, is recommended. This includes
organizational security measures such as the assignment of access authorization as well as technical
measures such as network segmentation.
The device can be integrated in a ring topology. The device is integrated via the terminal
connection for signal transmission (output 1) and the connection to the service interface (CDI-
RJ45) → 99.
