Conformance classes
PROFINET devices are categorized into conformance classes to simplify the evaluation and
selection of the devices for the users. The AMS 348
i
can use an existing Ethernet network
infrastructure and corresponds to Conformance Class B (CC-B). Thus, it supports the
following features:
• Cyclical RT communication
• Acyclic TCP/IP communication
• Alarms/diagnostics
• Automatic address assignment
• I&M 0 functionality
• Neighborhood detection basic functionality
• FAST Ethernet 100 Base-TX
• Convenient device exchange without engineering tools
• SNMP support

Measures to be performed prior to the initial commissioning
Before commissioning, familiarize yourself with the operation and configuration of the
AMS 348
i
.
Before connecting the supply voltage, recheck all connections and ensure that they have
been properly made.
Figure 9.4:
Connections of the AMS 348
i
Check the applied voltage. It must be in the range b18V … 30 V DC.
Connecting functional earth FE
Ensure that the functional earth (FE) is connected correctly.
Unimpaired operation is only guaranteed when the functional earth is connected properly.
All electrical disturbances (EMC couplings) are discharged via the functional earth
connection.
