Profinet (Process Field Network) is the open industrial Ethernet standard for communication in the automation technology.
Profinet uses TCP/IP and IT standards. It is capable for real-time Ethernet and enables the integration of fieldbus systems.
The Profinet concept is modular.
It basically differs in the perception of ProfinetIO and ProfinetCBA. Both channels are able to communicate at the same time and
on the same bus system either individually or in combination (parallel operation).
In the broader sense, ProfinetIO can be considered as direct successor of ProfibusDP.
ProfinetIO (Input - Output) is created in order to connect decentralized periphery with a controller. The available functions and the real-time attributes are divided
into the three conformance classes CC-A, CC-B and CC-C with respect of the different applications.
ProfinetCBA (Component Based Automation) is intended for component based communication via TCP/IP and the real-time communication in the modular plant engineering.
A ProfinetIO system consists of the following device types:
IO controller for automation tasks
IO device controlled by an IO controller. The IO device consists of several modules and submodules. The submodules contain individual input and output signals.
IO supervisor is a development tool (typically based on a PC) in order to parametrize and diagnose specific IO devices.
IO services & protocols RPC
IP, ARP, SNMP, DHCP
CSMA/CD, VLAN, DCP, MRP, MRRT, LLDP
Available Protocol Stacks
Universal protocol converter for small and distributed applications
