Connecting Client PC and Fieldbus Nodes

1. Mount the fieldbus node to the carrier rail.
Observe the installation instructions described in "Mounting" section.
2. Connect the 24V power supply to the supply module.
3. Connect an ETHERNET interface from the client PC to an ETHERNET
interface of the fieldbus controller.
4. Turn the operating voltage on.
Make sure that the mode selector is not in the bottom position.
After the power is switched on, the fieldbus controller is initialized. The fieldbus
controller determines the I/O module configuration and creates a process image.
During startup, the I/O LED (red) will flash. After a brief period, the I/O LED lights
up green, indicating that the fieldbus controller is operational.
If an error has occurred during startup, a fault code is flashed on the I/O LED.
For example it is indicated that port1 or port 2 has not been assigned yet an IP
address, if the I/O LED flashes first 6 times (indicating error code 6) and
afterwards either
4 times flashes (error argument 4 - no assigned IP address at port 1) or
10 times flashes (error argument 10 - no assigned IP address at port 2).

Allocating the IP Address to the Fieldbus Node

Use the ETHERNET interfaces X1, X2 only in separate subnets!
Note that it is necessary to select different subnets for the IP addresses of the
ETHERNET interfaces X1 and X2, to ensure that requested data is output to the
correct interface. For example, the subnet mask is: 255.255.255.0 (default value
of a fieldbus controller), then one of the first 3 place values of the IP address
must be different (e.g. IP address X1: 192.168.2.100, IP address X2:
192.168.1.200).
• Use address selection switch (DIP switch) to assign IP address
(manually).
• Automatic assignment of addresses via DHCP
(IP address via the fieldbus)
• Assigning IP Address via "WAGO Ethernet Settings"
(static IP address via the serial communication port)
• Assigning IP Address via PLC program
(Static IP address)
• Assigning IP Address via BootP server
(Static IP address via the fieldbus)
