Alternative procedure
Alternatively, you can write directly to a SIMATIC Micro Memory Card using a programming
device with an EPROM programming device installed or a PC connected to a SIMATIC USB
EPROM programming device and then use the memory card to transfer the device name to
the IM151-3 PN.
Proceed as described in the online help for HW Config under "Assign device name using a
memory card".
Forwarding the device name when the interface module is replaced
The device name of the IO device is saved to the SIMATIC Micro Memory Card.
To transfer the device name when exchanging the interface module IM151-3, pull the
SIMATIC Micro Memory Card out of the "old" IM151-3 and insert it in the "new one".
The IO device adopts the device name from the SIMATIC Micro Memory Card after
switching the power supply off/on. Then the station is addressable again and functions the
same as before the exchange.
Station flash test
If you are using multiple IO devices, multiple IO devices are also indicated in the "Assign
device name" dialog. In this case, you should compare the MAC address of the device with
the indicated MAC address and select the proper IO device.
The identification of IO devices in a system is facilitated by a station flash test. The flash test
is activated as follows:
1. In the "Assign device name" dialog, select one of the indicated IO devices.
2. Select a flash duration.
3. Click the "Flash on" button.
The LINK LED on the selected IO device flashes (open the flaps on the front cover of the
IM151-3).
