Figure 13.1: Example of an “Address Link Label”; the device type varies depending on the series
• The “Address Link Label” contains the MAC address (Media Access Control address) of the device
and makes it possible to enter the IP address and the device name manually.
The area of the “Address Link Label” on which the MAC address is printed can be separated from the
remainder of the stick-on label if necessary using the perforation.
• The “Address Link Label” can be removed from the device and affixed in the installation and layout
diagrams to designate the device.
• Once it is affixed in the documents, the “Address Link Label” establishes a unique reference between
the mounting location, the MAC address or the device, and the associated control program.
The time-consuming searching, reading, and manually writing down of the MAC addresses of all
devices installed in the system are eliminated.
Remove the “Address Link Label” from the device.
If necessary, add the IP address and the device name to the “Address Link Label”.
Affix the “Address Link Label” in the documents, e.g., in the installation diagram, according to the posi
-
tion of the device.
13.2.1 PROFINET
-
communication profile
The PROFINET communication profile defines how participants serially transmit their data via the trans
-
mission medium. Data exchange with the devices occurs primarily cyclically. For configuration, operation,
observation and alarm handling, acyclic communication services are, however, used as well.
Depending on the communication requirements, PROFINET offers suitable protocols and transfer
methods:
• Real Time communication (RT) via prioritized Ethernet frames:
• Cyclical process data (I/O data stored in the I/O area of the control)
• Alarms
• Neighborhood information
• Address assignment/address resolution via DCP
• TCP/UDP/IP communication via standard Ethernet TCP/UDP/IP frames:
• Establishing communication
• Acyclic data exchange, i.e., transfer of various types of information:
Parameters for the module configuration while communication is being established
I&M data (Identification & Maintenance functions)
Reading diagnostic information
Reading I/O data
Writing device data
13.2.2 Conformance Classes
PROFINET devices are categorized into conformance classes to simplify the evaluation and selection of
the devices for the users.
Each device with Ethernet interface is uniquely identified via the MAC address assigned during
production. The MAC address is also listed on the name plate of the device.
If multiple devices are commissioned in a system, the MAC address of each installed device
must be correctly assigned, e.g., during programming of the control.
