Note MAC IDs

1. Write down the controller's MAC addresses before you install the fieldbus
node.
If the fieldbus controller is already installed, turn off the operating voltage of
the fieldbus controller, then take the fieldbus controller out of the assembly
of your fieldbus node and note the MAC IDs of your fieldbus controller.
The MAC ID for port 1 is applied to the back of the fieldbus controller or on the
self-adhesive peel-off strip on the side of the fieldbus controller.
The MAC ID for port 2 results from incrementing (+1) of the MAC ID of port 1.
Example:
2. Plug the fieldbus controller into the assembly of the fieldbus node.
3. Use the fieldbus cable to connect the fieldbus connection of your
mechanically and electrically assembled fieldbus node to an open interface
on your PC.
The PC must be equipped with a network card for this connection. The
transfer rate then depends on the network card of your PC.
4. Start the PC that assumes the function of the master and BootP server.
5. Switch on the power at the fieldbus controller (DC 24 V power supply unit).
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 occurs during start-up indicated by the I/O LED flashing red, evaluate
the error code and argument and resolve the error.
More information about LED signaling
The exact description for evaluating the LED signal displayed is available in the
section "Diagnostics" > ... > "LED Signaling".
If a fault code is flashed on the I/O LED after startup with first 6 times (indicating
error code 6) and afterwards either
4 times flashes (error argument 4 - port 1) or
10 times flashes (error argument 10 - port 2),
it indicates, that no IP address is assigned depending on the error argument at
port 1 or at port 2.
