Communication
2.2 PROFINET communication
MAC address
Each PROFINET device is assigned a globally unique device identifier at the factory.
This 6-byte long device identifier is the MAC address.
The MAC address is divided up as follows:
● 3 bytes manufacturer's ID and
● 3 bytes device identifier (consecutive number).
The MAC address can generally be read from the front on the device,
e.g.: 08-00-06-6B-80-C0
OPC Unified Architecture (UA)
OPC Unified Architecture (UA) is the next generation technology of the OPC Foundation for
safe and reliable data transfer and defines access to industrial communication networks.
OPC UA client
An OPC UA client is a user program that accesses process data via the OPC UA interface.
Access to the process data is made possible by the OPC UA server.
OPC UA server
The OPC server provides the OPC client with a wide range of functions with which it can
communicate via industrial networks. SIMOCODE pro V PN (GP) provides extensive
process data via OPC UA.
PROFINET
Within the context of Totally Integrated Automation (TIA), PROFINET is the systematic
development of the following systems:
● PROFIBUS DP, the established fieldbus
● Industrial Ethernet, the communications bus for the cell level.
Experiences from both systems have been and are being integrated in PROFINET.
PROFINET was defined as an Ethernet-based automation standard of PROFIBUS
International (PROFIBUS Nutzerorganisation e. V.).
PROFINET IO controller
Device via which the connected IO devices are addressed. That means the IO controller
exchanges input and output signals with assigned field devices. The IO controller is often the
controller on which the automation program runs.
PROFINET IO Supervisor
PG/PC for commissioning and diagnostics.
