Configuration via rotary encoding switch

You can configure the address assignment and other func-

tions using rotary encoding switches.

After modifying the switch position, restart the device, as the

modification to the switch position does not take effect dur-

ing operation.

Figure 8

Rotary encoding switch

The code results from the sum of S1 x 10 plus S2 x 1. The

image shows code 77 (7 x 10 + 7).

9.1

Remote access

Switch position 00

At this switch position, it is possible to remotely configure the

device using corresponding tools (e.g., Startup+, web-

based management (WBM)).

Behavior during initial startup, after resetting the IP

parameters or after resetting to default settings

A valid IP address is not assigned (0.0.0.0) and communica-

tion is therefore not possible.

The device transmits continuous BootP requests (2 s, 4 s,

8 s, 2 s ...), until a valid IP address has been received.

Valid IP parameters are then automatically saved as config-

uration data on the device.

Each additional startup

If BootP is not explicitly deactivated, the device transmits

continuous BootP requests (2 s, 4 s, 8 s, 2 s, etc.), until a

valid IP address has been received.

Valid IP parameters are then automatically saved as config-

uration data on the device.

9.2

Manual address assignment

Switch position 01 ... 50

Default: BootP deactivated, DHCP activated

The first three octets in the IP address are preset as

192.168.0.x.

The subnet mask is 255.255.255.0.

Specify the last byte with the switch position.

As such, you can select IP addresses between 192.168.0.1

and 192.168.0.50.

Prior to transferring the IP address, a test is performed to

check for any potential IP address conflicts. If a conflict is

detected, the device temporarily switches the IP address to

0.0.0.0 (no IP communication). In this case, the NET LED

flashes red. Eliminate the conflict and restart the device.

9.3

DHCP name assignment

Switch position 51 ... 159

This switch position is used to easily specify the DHCP host

name for the device.

The host name is provided to the DHCP server via DHCP

options. This is therefore able to send a DNS update to the

DNS server.

The DNS name consists of one set part, which is based on

the order designation, and a variable part, which is deter-

mined by the switch position.

The first part of the station name is AXL-E-EIP-.

The set number is added.

This results in the following station names: AXL-E-EIP-051

... AXL-E-EIP-159.

Behavior during initial startup, after resetting the IP

parameters or after resetting to default settings

A valid IP address is not assigned (0.0.0.0) and communica-

tion is therefore not possible.

The device transmits continuous DHCP discover messages

until a valid IP address has been received.
