2 Safety
2.1 Intended Use
2.2 General Safety Information
The protection of operating personnel and the system against possi-
ble danger is not guaranteed if the control interface unit is not oper-
ated in accordance with its intended use.
The device may only be operated by appropriately qualified person-
nel in accordance with this operating manual.
Safety and correct functioning of the device cannot be guaranteed if
any operation other than that described in this operation manual is
performed.
The connecting of the equipment and any maintenance work to be
carried out with voltage applied to the equipment must only be per-
formed by appropriately qualified electrotechnical personnel.
In the case that a failure cannot be repaired, the device must be
taken out of operation and kept from inadvertently put back into
operation.
Repair work is to be carried out by the manufacturer only. Additions
or modifications to the equipment are not allowed and void the war-
ranty.
The operator is responsible for the observance of local safety stan-
dards.

power supply N Article no. 1310
The AS-i/PROFIBUS-Gateways serve to connect AS-Interface systems to the
PROFIBUS. They act as a Master for the AS-Interface and as a slave for the
PROFIBUS.
New AS-i Specification 2.1
The AS-i/PROFIBUS-DP Gateways already fulfil the new AS-i Specification 2.1.
This means:
• Up to 62 AS-Interface slaves can be connected per 1 AS-i network
• The transfer of analog signals via AS-i is integrated in the Masters
• All further functions of the new specification as e.g. the diagnosis of the AS-i pe-
ripheral fault are implemented.
All AS-i functions are provided cyclically via PROFIBUS-DP V0 and acyclically via
PROFIBUS-DP V1.
In the cyclic data transfer optionally up to 32 bytes I/O data are transfered for the
binary data of 1 AS-i network. Furthermore analog signals and all further com-
mands of the new AS-i specification can be transferred in the management chan-
nel via
PROFIBUS.
The serial PROFIBUS Master (art. no. 1258) and the AS-i Control Tools can be
used for the monitoring of the AS-i data online via the PROFIBUS-DP V1.
Advanced Diagnostics
Diagnostics, which go far beyond the standard diagnostics facilitate the simple de-
tection of the occassionally occuring configuration errors and further irritations to-

wards the AS-i communication. So in case of an error the down time of machines
can be minimized or you can initiate preventive maintenance.
Two Sorts of Housing
The AS-i PROFIBUS Gateways with one Master can be delivered in a housing for
cabinet mounting or in a field housing in IP65. The handling of the AS-i/PROFIBUS
Gateway in IP65 is identically with the AS-i/PROFIBUS-DP Gateway in IP20. The
high protection category IP65 makes the device suitable for applications in the ex-
treme industrial environments frequently encountered in the field. AS-Interface is
connected using the penetration technique of EMS (Electromechanical Interface).
PROFIBUS is connected with heavy gauge terminals and cage clamp terminal
blocks.
Commissioning and monitoring
The AS-i/PROFIBUS Gateways can be commissioned respectively programmed
with the help of the software "AS-i Control Tools" in combination with the
PROFIBUS-DP Master Simulator. The GSD file are included in the package.
Commissioning, debugging and setting up of the AS-i parameters without the soft-
ware can only be accomplished with the use of the push-buttons, the display and
the LEDs directly on the system.
Accessories:
Software "AS-i Control Tools" (Article no. 1203)
Serial PROFIBUS Master (Article no. 1258)
PROFIBUS-DP Master Simulator DP V1 (Article no. 1257)

4 Connections, Displays and Operating Keys
Devices in IP20:
On the front panel of the AS-i/PROFIBUS gateways in IP20 are:
• terminals to connect the power supply and the AS-i circuit
• a 9-pin SUB-D connector as PROFIBUS interface
•7LEDs
• a LC display
• 2 push-buttons (devices with full-graphic display: 4 push-buttons) to configure
the gateway
Devices in IP65:
The devices in IP65 have the terminals for PROFIBUS (cage clamp terminals) and
the push buttons under the top of the housing to prevent liquids from entering. The
AS-interface is connected with the electromechanical interface with penetration
technique developed for AS-i at the bottom of the housing.
4.1 Power Supply Concepts and AS-i Connection Techniques
An AS-i power supply has to be used which also supplies the AS-i master with po-
wer and can be connected to the AS-i cable like all the other AS-i components at
any place.
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 addi-
tional 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.

4.1.1 Single Masters in IP65
Every AS-i master and all the AS-i gateways in IP65 come with power supply A.
The AS-i master is connected to AS-i using the penetration technique of the elec-
tromechanical interface which is common with AS-i slaves as well.

The terminals have the following functions:
+ "AS-i +", Actuator Sensor Interface, positive terminal
- "AS-i -", Actuator Sensor Interface, negative terminal
GND Ground terminal, used for better EMC.
Should be connected with a short wire to machine GND.
Connections of the AS-/PROFIBUS gateway with graphic display (1307)
The AS-i/PROFIBUS gateway (art. no. 1307) with graphic display, power supply
A, has an additional AS-i connection.
The terminals have the following functions:
+ "AS-i +", Actuator Sensor Interface, positive terminal
- "AS-i -", Actuator Sensor Interface, negative terminal
GND Ground terminal, used for better EMC.
Should be connected with a short wire to machine GND.

4.1.4 Double Master in IP20 with Power Supply N
The terminals have the following functions:
+ "AS-i +", Actuator Sensor Interface 1 or 2, positive terminal
These terminals are connected internally with point a2 of jumper "J+".
- "AS-i -", Actuator Sensor Interface 1 or 2, negative terminal
These terminals are connected internally with point b2 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.
J+, J- Jumpers for selecting the power supply of AS-i
jumpers closed:
The AS-i circuits are powered by the master power supply.
Master power supply and AS-i network are then decoupled with coils.
jumpers open:
With the jumpers open (or missing), the AS-i master must be powered
by a separate AS-i power supply.
The AS-i power supply can be either connected to the jumper terminals
or to the AS-i line in the field.
Operation without AS-i power supply
When the jumpers are closed, the AS-i networks are powered by the master's po-
wer 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 voltage
source.
This variant requires only one power supply for 2 AS-i circuits!
