Assignment of the device names to IP addresses
Transfer the PROFINET configuration to the IO Controller (S7 PLC)
Ä
Transfer the PROFINET configuration to the IO Controller (S7 PLC).
Following successful transfer, the following activities take place automatically:
• Check of device names
• Assignment of the IP addresses that were configured in the HW Config to the IO devices
• Establishment of a connection between the IO Controller and configured IO devices
• Cyclical data exchange
NOTICE
Participants that have not been "named" cannot be contacted yet at this point in time!
Name the device
PROFINET defines the "naming of the device" as the creation of a name-based relationship for a
PROFINET device.
Ä
Set the device name.
• The PROFINET device has a unique MAC address that is part of the factory settings. The MAC ad-
dress may be found on the name plate of the device. Multiple devices can be distinguished by the MAC
addresses displayed.
• This information is used to assign a unique, plant-specific device name ("NameOfStation") to the device
via the "Discovery and Configuration Protocol (DCP)".
• Every time the system is started up, PROFINET uses the DCP protocol for the IP address assignment,
provided the IO-device is located in the same subnet.
Ä
Assign the device names to the configured IO devices.
• Select the code reader on the basis of the MAC address.
• The code reader is then assigned the unique device name. The device name must match the device
name configured in the HW Config.
