Checking the assignment
You can find an overview of the communication relationships in the "IO communication" tab
in the tabular area of the network view. This table is context-sensitive for selection in the
graphic area:
•
Selection of the interface shows the I/O communication of the respective interface.
• Selection of the CPU shows all I/O communication of the CPU (including PROFIBUS).
• Selection of the station (as in the above figure) interface shows the I/O communication of
the complete station.
Information on S7-1500R/H
You can find the procedure for assigning an IO device with system redundancy S2 to the
redundant S7-1500R/H system in section Assigning IO device to the redundant S7-1500R/H
system (Page 1).
3.2 Device name and IP address
Introduction
In order that the PROFINET device can be addressed as node on PROFINET, the following are
required:
•
A unique PROFINET device name
• A unique IP address in the relevant IP subnet
STEP 7 assigns a device name during the arrangement of a PROFINET device in the hardware
and network editor. The IP addresses are typically assigned automatically by STEP 7 and
assigned to the devices based on the device name.
You can change the name and IP address manually.
