Conformance Classes

PROFINET devices are categorized into conformance classes to simplify the evaluation and selection of
the devices for the users.
The DDLS 548i corresponds to Conformance Class B (CC-B) and can use an existing Ethernet network in-
frastructure.
The DDLS 548i supports the following characteristics:
• Cyclical RT communication
• Acyclic TCP/IP communication
• Alarms/diagnostics
• Automatic address assignment
• Neighborhood detection basic functionality
• FAST Ethernet 100 Base-TX/FX
• Convenient device exchange without engineering tools
• SNMP support
7.1.3 DDLS 548i single-port device
The DDLS 548i is registered and certified as a single-port device in accordance with the PNO (PROFIBUS
user organization) device classifications. This classification is stored in the GSDML file of the DDLS 548i,
where it cannot be modified.
• A DDLS 548i device is shown with a Tx port in the hardware configuration in accordance with this clas-
sification (connection of the PROFINET data line).
• Although it is physically present, the Fx port is not displayed in the hardware configuration as the opti-
cal link to the mutually opposing DDLS 548i device.

Topology editor
When a PROFINET network is created with a topology editor, port-specific networking of the participants is
configured.
Although it is physically present, the Fx port is not displayed in the topology editor as the optical link to the
mutually opposing DDLS 548i device.
