3Introduction
3.1 Overview
The AS-i/DeviceNet-Gateway is a master/slave gateway designed to allow communi-
cation between an AS-i network and a DeviceNet network. The gateway acts as a
simple DeviceNet device and can be classified as a Group 2 slave only. Baud rates
from 125k to 500k baud can be implemented. The MAC ID and baud rate are config-
ured using the selector buttons located on the front panel.
The gateway is a master for the AS-i network. All the features of the AS-i network are
availablewhenusingthe gateway, including 31nodecapability,5ms scan time,noise
immunity, two wire unshielded power/communication cable, and immediate fault iden-
tification.Byusingthe selector buttons, theusercanconfigurenode addresses onthe
AS-i network and change the modes of operation from protected operating mode (run
mode) to configuration mode (projecting mode).
The gateway is a slave for the DeviceNet network, consuming one node on De-
viceNet. Quick connection to DeviceNet is obtained through the 5 position, open style
connectorlocatedon the frontpanelof the gateway.Communicationsupported by the
gateway is polled I/O and explicit messaging. Strobed I/O is not supported.
3.2 Features
The AS-i/DeviceNet Gateway...
•allows simple connection between AS-i and DeviceNet networks.
•enhances features of both networks.
•is classified as a Group 2 slave only.
•has dual function LCD display.
•has immediate error diagnostics.

•GND, Ground terminal, used for better EMC. Should be connected with a short wire

The AS-i Masters as well as all the AS-i gateways of the Bihl+Wiede-
mann GmbH are available with two different power supply concepts,
"master power supply A" and "master power supply N".
The AS-i masters with master power supply A do not need a voltage
supply of their own. They can be powered completely out of the AS-i
line (the power consumption is about 200 mA from AS-i). An additional
24 V voltage source is not necessary. The AS-i master merely requires
the connection to the AS-i line. When the AS-i power supply is switched
on, the master starts to operate.

4.2.2 Terminals with power supply N
At the bottom of the unit there are 10 terminals for the power supply and the AS-i net-
work. The jumper settings (J+, J-) decide whether AS-i is powered by a separate AS-i
power supply or by the power supply that also provides the AS-i Master.
The terminals have the following functions:
+"AS-i +", Actuator Sensor Interface, positive terminal
This terminal is connected internally with the center contact of jumper "J+".
-"AS-i -", Actuator Sensor Interface, negative terminal
This terminal is connected internally with the center contact of jumper "J-".
24V Master power supply, positive terminal (18 - 31.6 V DC)
0V Master power supply, negative terminal
GND Ground terminal, used for better EMC.
Should be connected with a short wire to machine GND.
Connection samples for the AS-i power supply:

J+, J- Jumpers for selecting the power supply of AS-i
"int pwr" position (closed):
AS-i is powered by the master power supply.
Master power supply and AS-i network are then decoupled with coils.
"ext pwr" position (open):
With the jumper open (or missing), the AS-i network must be powered by
a separate AS-i power supply.
The AS-ipowersupply can beconnectedtothe jumperortothe AS-i cable
in the field.
Operation without AS-i power supply
When the jumpers are in position "int pwr", the AS-i network is powered by the mas-
ter's power supply. For test purposes, it is possible to use a conventional 24 V DC
power supply to supply the AS-i network. You get optimum results with a 30 V DC volt-
age source.
For the following wiring scheme the current through the AS-i mas-
ter must not exceed 2.8 A.

This connection technique serves also for providing more than one AS-i Master out of
one master power supply because each AS-i circuit is decoupled with its own in the
AS-i Master integrated coils.

ply.

Do not try to provide the AS-i Master with power supply N out of the AS-i power supply
of the AS-i circuit („backwards“), because the additional decoupling coils would bur-
den the AS-i line and cause erroneous AS-i telegrams.
4.2.3 Terminals of a Device with Power Supply DeviceNet
The AS-i circuit must be powered by an AS-i power supply as follows:
The AS-i/DeviceNet gateway itself is powered by DeviceNet.
4.3 AS-i Network Connection
At the base of the gateway are 3 terminals for the connection of the AS-i network. The
individual terminals are as follows:

config err Configuration error
At least one configured slave is missing, or at least one detected
slave is not projected or for at least one projected and detected
slave the actual configuration data does not match the nominal
configuration data.

Exactly one slave is missing in protected operating mode. The
slave can be replaced by another slave of the same type with ad-
dress zero. The master addresses the new slave to the faulty ad-
dress and thus eliminates the configuration error.

5.1 Setting MAC ID and Baud Rate
To set the MAC ID and baud rate, refer to the front panel of the gateway. Locate the
two buttons on the front panel marked "mode" and "set". By pressing both buttons si-
multaneously for approximately 5 seconds, the actual MAC ID will appear on the LCD
display. MAC ID can be changed by pressing the "set" button until the desired MAC
ID has been reached. To store the MAC ID, press the "mode" button. Now the LCD
screen displays a 0, 1, or 2. See the chart below for the meaning of the code.
Press the "set" button until the desired code is reached. Again press the "mode" but-
ton to store the baud rate. The setting of the MAC ID and baud rate is complete.
5.2 I/O Data Interpretation
5.2.1 Input Data
Data sent from the AS-i slaves to the gateway consumes 17 bytes of data. All data
sent will use fragmented I/O.
