Function and features

• The AS-i DP gateway integrates one or two AS-i masters
(AC1325/AC1326, both in accordance with the AS-i version 2.1) and
a Profibus DP interface
• It controls the exchange of data to the sensor/actuator level
• communicates with the higher control level (in the gateway mode)
Interface RS232C
The serial interface cannot be used.

Profibus-DP interface

• Baud rate 9600 to 12MBaud
• Max. distance between gateway and host: depending on the baud
rate
• Potential separation from the gateway power supply
• Up to 31 gateways connected in parallel
• Pin connection: pin 3: signal B, pin 8: signal A

Installation

Fix the AS-i DP gateway onto a 35mm rail. 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.
Electrical connection
Disconnect the installation from power. Connect the unit as indi-
cated 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.
