Configuring PROFINET IO Devices
4.4.5 Changing the IP-Address or the Device Name During Operation
Assigning an IP address or device name for a single node
Before a new IP address or a device name can be assigned, the following
conditions must be met:
There is no data being exchanged with the IO controller.
If the SIMATIC Manager or the list of accessible nodes is open, you can assign
each PROFINET-device an/another IP address another device name. To do this,
select the PLC > Assign Ethernet Address menu command.
Changing IP addresses from a central location
If you have to check or change the IP addressees for several IO devices, proceed
as follows:
1. In HW Config, select the PROFINET IO system (the "railroad track") and then
select Edit > PROFINET IO > PROFINET IO System > IP Addresses menu
command. Alternative method: you can also find this function by selecting an
IO system and then right-clicking to display the context menu.
2. The dialog box that is then displayed shows all the IO devices with their current
device names and IP addresses. You can change all the IP addresses from
this central location.
3. Download the changed IP addresses (menu command: PLC > Download to
Module).
When an IO controller or an IO device is selected, you can also call this function in
NetPro by selecting the Edit > PROFINET IO > PROFINET IO System > IP
Addresses menu command.
