9.3.1 Manual IP address assignment with address switch

Fig. 5: Address switches S1 and S2 on the bus coupler
The two rotary switches S1 and S2 for manual valve system IP address assign-
ment are located underneath the window (3).
• Switch S1: The higher nibble of the last block of the IP address is set at
switch S1. Switch S1 is labeled using the hexadecimal system from 0 to F.
• Switch S2: The lower nibble of the last block of the IP address is set on switch
S2. Switch S2 is labeled using the hexadecimal system from 0 to F.
The rotary switches are set to 0x00 by default. This activates address assignment
via DHCP server.
Proceed as follows during addressing.
1. Ensure that each IP address exists only once on your network and note that
the address 0xFF or 255 is reserved.
2. Disconnect the bus coupler from the power supply UL.
3. Set the station address at the switches S1 and S2 (see Fig. 5). For this, set the
rotary switch to a position between 1 and 254 for decimal or 0x01 and 0xFE
for hexadecimal:
- S1: High nibble from 0 to F
- S2: Low nibble from 0 to F
4. Reconnect the power supply UL.
The system will be initialized using the address defined on the bus coupler.
The IP address of the bus coupler is set to 192.168.1.xxx, where "xxx" corre-
sponds to the setting of the rotary switch. The subnet mask is set to
255.255.255.0 and the gateway address to 0.0.0.0. Address assignment via
DHCP is deactivated.
Table 20 contains a number of addressing examples.

9.3.2 IP address assignment with DHCP server

Setting the IP address to DHCP function
1. Disconnect the bus coupler from the power supply UL before changing the
positions of switches S1 and S2.
2. Only set the address to 0x00 afterwards.
DHCP mode is active after the bus coupler has been restarted.
Assigning an IP address
After you have set the address 0x00 on the bus coupler, you can assign it an IP ad-
dress.
The procedure to assign an IP address to the bus coupler depends on
the PLC configuration program or your DHCP program. Please see the
operating instructions for the program for more information.
The following example is based on the Rockwell software RSLogix 5000 with
BOOTP/DHCP server. The PLC configuration and assignment of IP addresses can
also be performed with a different PLC configuration program or DHCP program.
Danger of injury if changes are made to the settings during operation.
Uncontrolled movement of the actuators is possible!
Never change the settings during operation.
u
The bus coupler uses its MAC address to contact the DHCP server. You can use
this address to identify the bus coupler. The MAC address of the bus coupler can
be found on the rating plate.
Select the bus coupler using its MAC address in the "Request History" pane.
u
When the device has responded, you can add it to the reference list and assign it
an IP address.
1. Click the "Add to Relation List" button.
The "New Entry" window opens.
2. Enter the required IP address in the "IP Address" field and press "OK" to con-
firm.
As soon as the bus coupler has been added to the list and has sent the next
DHCP request, the DHCP server will assign the specified address to the bus
coupler.
