Assigning Internet Protocol (IP) addresses
Assigning the IP addresses
In a PROFINET network, each device must also have an Internet Protocol (IP) address. This
address allows the device to deliver data on a more complex, routed network:
●
If you have programming or other network devices that use an on-board adapter card
connected to your plant LAN or an Ethernet-to-USB adapter card connected to an
isolated network, you must assign IP addresses to them. Refer to "Assigning IP
addresses to programming and network devices" (Page 123) for more information.
●
You can also assign an IP address to a CPU or network device online. This is particularly
useful in an initial device configuration. Refer to "Assigning an IP address to a CPU
online" (Page 123) for more information.
●
After you have configured your CPU or network device in your project, you can configure
parameters for the PROFINET interface, to include its IP address. Refer to "Configuring
an IP address for a CPU in your project" (Page 125) for more information.
10.2.3.4
Testing your PROFINET network
After completing the configuration, you must download your project to the CPU. All IP
addresses are configured when you download the project.
The CPU "Download to device" function and its "Extended download to device" dialog can
show all accessible network devices and whether or not unique IP addresses have been
assigned to all devices. Refer to "Testing the PROFINET network" (Page 129) for more
information
10.2.4
HMI-to-PLC communication
The CPU supports PROFINET
communications connections to HMIs. The
following requirements must be considered
when setting up communications between
CPUs and HMIs:
Configuration/Setup:
●
The PROFINET port of the CPU must be configured to connect with the HMI.
●
The HMI must be setup and configured.
