Starting up ETHERNET TCP/IP fieldbus nodes

This chapter shows the step-by-step procedure for starting up a
WAGO ETHERNET TCP/IP fieldbus node. The following also contains a de-
scription of how to read out the coupler-internal HTML pages.
Attention
This description is given as an example and is limited to the execution of a
local startup of an individual ETHERNET fieldbus node with a computer
running under windows which is not connected to a network.
Direct Internet connection should only be performed by an authorized net-
work administrator and is, therefore, not described in this manual.
The procedure contains the following steps:
1. Noting the MAC-ID and establishing the fieldbus node
2. Connecting the PC and fieldbus node
3. Determining the IP address
4. Allocation of the IP address to the fieldbus node
5. Function of the fieldbus tests
6. Reading out information as HTML pages
3.1.6.1

Note the MAC-ID and establish the fieldbus node

Before establishing your fieldbus node, please note the hardware address
(MAC-ID) of your ETHERNET fieldbus coupler.
This is located on the rear of the fieldbus coupler and on the self-adhesive tear-
off label on the side of the fieldbus coupler.
MAC-ID of the fieldbus coupler will be in this format:
----- ----- ----- ----- ----- -----.
3.1.6.2

Connecting PC and fieldbus node

Connect the assembled ETHERNET TCP/IP fieldbus node via a hub or di-
rectly to the PC using a 10Base-T cable.
Attention
For a direct connection, a crossover cable is required instead of a parallel cable.
Now start the PC, functioning as master and BootP server, and switch on the
voltage supply on the fieldbus coupler (DC 24 V power pack). Once the oper-
ating voltage has been switched on, the initialization starts. The fieldbus cou-
pler determines the configuration of the bus modules and creates the process
image.
During the startup the 'I/O' LED (Red) flashes at high frequency.
When the 'I/O' LED and the 'ON' LED light up green, the fieldbus coupler is
ready for operation.
If an error has occurred during startup, it is indicated as an error code by the
'I/O'-LED flashing (red).
