1 Safety instructions
• Please read the product description prior to set-up of the unit. Ensure that the
product is suitable for your application without any restrictions.
• The unit conforms to the relevant regulations and EC directives.
• Improper or non-intended use may lead to malfunctions of the unit or to
unwanted effects in your application.
That is why installation, electrical connection, set-up, operation and maintenance
of the unit must only be carried out by qualified personnel authorised by the
machine operator.
2 Functions and features
• The AS-i DP gateway integrates 2 AS-i masters (AS-i version 3.0) and a
Profibus DP interface
• It controls the exchange of data to the sensor / actuator level and
• communicates with the higher control level (in the gateway mode)
3 Interface RS232C
The serial interface cannot be used.
4 Profibus DP interface
• Baud rate 9600 baud to 12 Mbaud
• Max. distance between gateway and host: depending on the baud rate
• Electrical separation from the gateway power supply
• Up to 31 gateways connected in parallel
• Pin connection: pin 3: signal B, pin 8: signal A
5 Installation
Fix the AS-i DP gateway onto a 35 mm rail which has an electrically safe ground
connection. The protection rating of the unit is IP20, therefore it should be
mounted in a protected location (e.g. control cabinet).
Ensure a condensation-free environment. Avoid excessive dust, vibration
and shock. The air circulation through the vents must not be impeded.
Avoid installation in direct vicinity of frequency inverters.

6 Electrical connection
Disconnect the installation from power. Connect the unit as indicated on the
terminals. Never connect the minus potentials to each other or the minus
potentials to the FE connection. Ensure an electrically save ground connection
between AS-i DP gateway (terminal FE) and ground of the unit.
Supply the AS-i DP gateway with a 24 V DC voltage (20...30 V PELV), e.g. from
the 24 V power supply DN2011 of ifm electronic. The connection is made to the
terminals +24 V and 0 V.
7 Operating and display elements
You are informed about the state of the master and the connected system by
means of four diagnostic LEDs on the SmartLink DP.
• LED PWR/COM lights: AS-i voltage present, at least one slave was detected
• LED PWR/COM flashes: AS-i voltage present, but no slave was detected
correctly
• LED PROJ lights: Projection mode active, the configuration monitoring is
deactivated
• LED PROJ flashes: Projection mode active, changeover to protected mode not
possible as a slave with the address 0 is connected
• LED CONF/PF lights: Projected and current configuration do not match
• LED CONF/PF flashes: Peripheral fault on at least one connected slave
• LED Profibus DP lights: Profibus DP bus error

8 Operation
To operate an AS-i system a special AS-i power supply is required (e.g. AC1216).
The AS-i power supply supplies the yellow AS-i cable with energy and implements
a data decoupling to the voltage regulator of the power supply. Standard switched-
mode power supplies would consider the AS-i data signals as interference signals
and suppress them.
Disconnect the power supply before connecting the AS-i DP gateway.
The AS-i system is operated ungrounded. AS-i + and AS-i - are to be
symmetrical to the ground potential of the installation. Ensure a low-
resistance connection of the symmetry point of the AS-i power supply
(terminal "shield") to the ground of the installation.
