■ Overview
DP/AS-i LINK Advanced
The DP/AS-i LINK Advanced is a compact Network transition be-
tween
PROFIBUS (DP Slave) and AS-Interface, with the following
features:
• Single and double AS-Interface master (according to
AS-Interface Specification V3.0) for connection of
62 AS-Interface slaves or 124 AS-Interface slaves
(with a double master)
• Integrated analog value transmission (all analog profiles)
• Integrated ground-fault monitoring for the AS-Interface cable
• User-friendly local diagnostics and start-up by means of a full
graphic display and control keys or through a web interface
with a standard browser on the PC screen
• Optimum TIA integration using STEP 7
• Integration in non-Siemens engineering tools using the
PROFIBUS GSD file
• Vertical integration (standard web interface) through Industrial
Ethernet
• Supply voltage from the AS-Interface shaped cable or alterna-
tively with 24 V DC (optional)
• Suitable for AS-i Power24V (product version 4 and higher /
firmware version 2.1.20) and standard AS-i (30 V)
• Module exchange without entering the connection parameters
(PROFIBUS address etc) using C-PLUG (optional)
Design
• Compact plastic enclosure in degree of protection IP20 for
standard rail mounting
• COMBICON plug-in screw terminals
• Compact design:
- Pixel graphics display in the front panel for detailed indica-
tion of the operating state and readiness for operation of all
connected AS-Interface slaves
- 6 pushbuttons for starting up and testing the AS-Interface
line directly on the DP/AS-i LINK Advanced
- LED indication of the operating state of PROFIBUS DP and
AS-Interface
- Integrated Ethernet port (RJ45 socket) for user-friendly start-
up, diagnostics and testing of DP/AS-i LINK Advanced
through a web interface using a standard browser
• Small mounting depth thanks to recessed plug mounting
• Operation without fans and batteries
Functionality
Communication
The DP/AS-i LINK Advanced enables a PROFIBUS DP master to
cyclically access the I/O data of all the slaves of a lower-level
AS-Interface segment. Also supported are the expanded slave
types with higher I/O data volume according to AS-i Specifica-
tion V3.0.
The DP/AS-i LINK Advanced occupies the following address
area:
• As a single master: 32 bytes of input data and 32 bytes of out-
put data in which the I/O data of the connected AS-Interface
slaves (standard and A/B slaves) of an AS-i line are stored.
• A double master occupies twice the number of bytes.
The size of the input/output image can be compressed so that
only the actually required I/O address area is occupied in the
system of the DP master.
The integrated evaluation of analog signals is just as easy as ac-
cess to digital values because the analog process data also lie
directly in the I/O address area of the CPU.
PROFIBUS DP-V1 Masters also provide the option of triggering
AS-Interface Master calls over the acyclic PROFIBUS services
(e. g. write parameters, amend addresses, read diagnostic
values).
Using an operating display in AS-i Link it is possible to fully com-
mission the lower-level AS-Interface line.
DP/AS-i LINK Advanced is equipped with an additional Ethernet
port which enables use of the integrated web server. The web
server can be called up with any standard web browser (e. g. In-
ternet Explorer) without additional software. It allows all diagnos-
tics information to be shown on the PC and the bus configuration
and, if applicable, any adjustments, to be displayed. Firmware
updates are also possible using this port.
The optional C-PLUG supports module exchange without enter-
ing the connection parameters (IP address etc.), keeping down-
times to a minimum in the event of a fault.
Diagnostics
The following diagnostics is possible using LEDs, the display
and control keys, web interface or STEP 7:
• Operating state of the DP/AS-i LINK Advanced
• Status of the link as a PROFIBUS DP slave
• Diagnostics of the AS-Interface network
• Message frame statistics
• Standard diagnostics pages in the web interface for fast diag-
nostics access through Ethernet using a standard browser
• For the use of the web interfaces are no network settings on
the PC necessary (Zeroconf procedure).
• The reporting of diagnostic events is optional via E-Mail or
SNMP Trap possible. The integrated diagnostic buffer saves
the events including time stamp.
Configuration
The DP/AS-i LINK Advanced can be configured as follows:
• With STEP 7 as of V5.4: With STEP 7 configuring the AS-Inter-
face configuration can be uploaded in STEP 7. Can also be
AS-Interface slaves from Siemens conveniently configure in
HW Config (slave selection dialog).
• By adopting the ACTUAL configuration of the AS-Interface on
the display
• Alternatively DP/AS-i LINK Advanced can be integrated into
the engineering tool over the PROFIBUS GSD file (e. g. for
STEP 7 versions below V5.4 or engineering tools from third-
party software houses).
