PROFINET Device
All PROFINET devices are equipped with at least one Industrial Ethernet port. A PROFINET
device can also have a PROFIBUS connection (master with proxy functionality).
PROFINET IO
Within the framework of PROFINET, PROFINET IO represents a communication concept for
the implementation of modular, distributed applications.
PROFINET IO allows you to create automation solutions, which are familiar to you from
PROFIBUS.
Implementation of PROFINET IO is effected on the one hand by means of the PROFINET
standard for automation devices and on the other by means of the STEP 7 engineering tool.
This means that you have the same application view in STEP 7 regardless of whether you
are configuring PROFINET devices or PROFIBUS devices. Programming your user program
is essentially the same for PROFINET IO and PROFIBUS DP if you use the extended blocks
and system status lists for PROFINET IO.
PROFINET IO Controller
Device used to address connected IO Devices. That means: the IO Controller exchanges
input and output signals with assigned field devices. The IO Controller is usually the
controller running the automation program.
PROFINET IO Device
Distributed field device which is assigned to one of the IO Controllers (remote IO, valve
blocks, frequency converters, switches).
Reference potential
Reference potential for the evaluation / measuring of the voltages of participating circuits.
SELV
Safety Extra Low Voltage
SNMP
SNMP (Simple Network Management Protocol) is the standardized protocol for diagnosing
and parameterizing the Ethernet network infrastructure.
In the office area and in automation technology, devices support a wide range of
manufacturers on the Ethernet SNMP.
SNMP-based applications can be operated parallel to applications with PROFINET on the
same network.
The scope of the supported functions varies depending on the device type. A switch, for
example, has more functions than a CP 1616.
