11.3 Procedure for PROFINET IO
CPU 410 Process Automation/CPU 410 SMART
160 System Manual, 05/2017, A5E31622160-AC
Within a PROFINET IO subsystem, you must assign an NoS (Name of Station) to an added
IO device.
You must set the NoS locally on the interface module of the IO device.
:
Prior to local installation, configure the NoS of the interface modules in a separate network.
The NoS is enough for the IO controller that is to address the device. However, you must
make check that the IO device does not have an IPv4 address that is already assigned in the
system.
Rebuild hardware when adding an IO device
Procedure
If you are planning to add an IO device using CiR and the device does not support
PROFINET LLDP mode V2.3, check in HW Config to see which LLDP mode is set in the IO
controller. You cannot add the IO device using CiR if the option PROFINET LLDP mode
V2.3 is set.
When adding an IO device to a PROFINET subsystem, make sure that no bus cables are
disconnected that could lead to device failure.
You can do this as follows:
● Install additional ports at the future installation sites in the PROFINET subsystem to be
expanded. Connect the new IO device to these ports if necessary.
● If permitted by the plant configuration, you can integrate switches in the PROFINET
subsystem. In this case, follow these steps when adding an IO device:
Connect the new IO device to previously unused ports of a switch. In doing so, observe
the applicable installation guidelines (see
Installation manual: Automation System S7-400
Configuration and Use)
.
Change process image partition assignment
Procedure
You change the assignment of the process image partition of an existing module or a
compact slave as follows:
1. Specify the new process image partition in the "Addresses" tab of the Properties window
of the module or slave.
2. Download the changed configuration with HW Config.
