2.3. 1 PROFINET interface with integrated switch
abstract
PROFINET devices in SIMATIC product line have PROFINET interface (with or without integrated switch).
PROFINET devices with integrated switches usually have two ports for the linear bus structure of the network. also
Provide PROFINET devices with three or more ports to connect the tree topology.
The following describes the properties, rules and representations of PROFINET interface naming in STEP 7.
superiority
PROFINET devices with integrated switches can be used to create systems with linear or tree topology. No need to attach
An external switch is added.
attribute
Each PROFINET device in the network is uniquely identified by its PROFINET interface. To this end, each
PROFINET interfaces are
MAC address (factory default)
●IP address
● Equipment name (workstation name)
