Assigning A Device Name And Ip Address - Siemens SIMATIC ET 200AL System Manual

Parameter assignment/addressing
3.2 Device name and IP address
Reading out an IP address in the user program
You can read out the IP address of a PROFINET device in the user program of a S7-1500 CPU.
You can find information in this FAQ

3.2.3

Assigning a device name and IP address

Assigning an IP address and subnet mask for an IO controller for the first time
You have the following options:
• Using a programming device or PC:
Connect your programming device/PC to the same network as the relevant PROFINET
device. The interface of the programming device/PC must be set to TCP/IP mode. During
the download, first of all display all available devices via the "Accessible devices" download
dialog box. Select the target device via its MAC address and then assign its IP address
before you download the hardware configuration including the configured IP address (IP
address is saved retentively).
• Using the display of a S7-1500 CPU:
The S7-1500 CPUs have a front cover with a display and operating keys. You can use this
display to assign or change the IP address. To set the IP address, navigate on the display
via the menu items "Settings" > "Addresses" > "X1 (IE/PN)" > "Parameters".
• Using a memory card:
If your PROFINET device is equipped for a memory card (Micro Memory Card/SIMATIC
memory card), plug this into your programming device/PC and save the hardware
configuration together with the configured IP address on this memory card. Then plug the
memory card into the PROFINET device. Once inserted, the PROFINET device automatically
applies the IP address.
If you have saved a configuration to the memory card with the "IP address is set directly at
the device" option, you must assign the IP address using a different method after inserting
the memory card (see section Permitting changes to the device name and IP address
directly on the device (Page 1)).
Assigning device names and IP address for "Device replacement without exchangeable
medium/programming device"
For devices without exchangeable medium (e.g., ET 200MP, ET 200SP) and devices that
support "Device replacement without exchangeable medium/PG" (e.g., ET 200S), the IO
controller can identify the device without name from the neighbor relationships specified by
the set topology and from actual neighbor relationships determined by the real PROFINET
devices. The IO controller then assigns the PROFINET device the configured name and
incorporates the PROFINET device in the user data traffic. (See also Device replacement
without exchangeable medium (Page 1)).
