more of the additional individual addresses could be

assigned twice. When during normal operation the

learning button is pressed for more than 10 seconds all

additional individual addresses in the IP Interface

N148/22 are reset to the default value (15.15.255) and

the programming LED is turned off.

IP address assignment

Please consult your network administrator regarding

configuration of the parameters device IP address,

subnet mask, and DHCP.

The IP address of the IP Interface N148/22 is assigned

manually using ETS, automatically by a DHCP server in

the IP network, or by the device itself (AutoIP).

Assignment of the IP address by a DHCP server allows

for changes of the device IP address without using

ETS. Configuration of the DHCP server may require the

MAC address, which is printed on the device. If a

DHCP server is not available the device assigns itself

an IP address (AutoIP).

Default factory settings

The IP Interface ships with these default factory

settings:

· Physical address of the IP Interface:

15.15.15 (= FFFF hex)

· IP address assignment via DHCP

Application programs

The IP Interface N148/22 can be configured with

ETS2 v1.2 or higher.

It requires the application program "12 CO IP

Interface 720002".
