Overview
IE/AS-i LINK PN IO
The IE/AS-i LINK PN IO is a compact network transition between
PROFINET/Industrial Ethernet (PROFINET IO Device) 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
PROFINET GSD file
• Vertical integration (standard web interface) through Industrial
Ethernet
• Supply via AS-Interface cable or with 24 V DC
• Suitable for AS-i Power24V (product version 2 and higher /
firmware version 2.0.20) and standard AS-i (30 V)
• Module exchange without entering the connection parameters
(IP address etc) using C-PLUG (optional)
• Costs saved by the double AS-Interface master when large
volumes of project data are involved
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
- Six pushbuttons for starting up and testing the AS-Interface
line directly on the IE/AS-i LINK PN IO
- LED indication of the operating state of PROFINET IO and
AS-Interface
- Integrated 2-port switch (RJ45 socket) for connection to In-
dustrial Ethernet supports the line topology with an external
switch
• Small mounting depth thanks to recessed plug mounting
• Operation without fans and batteries
Functionality
Communication
The IE/AS-i LINK PN IO enables a PROFINET IO controller 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 IE/AS-i LINK PN IO occupies the following address area:
• As a single master or IO controller with full expansion: 62 bytes
of input data and 62 bytes of output 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.
• As double master, double 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.
PROFINET IO controllers are able in addition to initiate AS-Inter-
face master calls (e. g. to write parameters, change addresses,
read diagnostic values) through the acyclic PROFINET services.
Using an operating display in AS-Interface Link it is possible to
fully commission the lower-level AS-i line.
The IE/AS-i LINK PN IO is equipped with two Ethernet ports
which are connected by an internal switch. With the Ethernet it is
possible in addition to use 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 enables the PC to
present all diagnostics information and to display the set bus
configuration and parameters as well as their adaptation where
applicable. 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 the display and con-
trol keys, web interface or STEP 7:
• Operating state of the E/AS-i LINK PN IO
• Status of the link as a PROFINET IO device
• 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 IE/AS-i LINK PN IO is configured as follows:
• STEP 7 V5.4 or higher is required for configuring the full func-
tional scope of the IE/AS-i LINK PN IO. With STEP 7 configur-
ing the AS-Interface configuration can be uploaded in STEP 7
V5.4 SP2 and higher. Can also be AS-Interface slaves from
Siemens conveniently configure in HW Config (slave selection
dialog).
• Alternatively, E/AS-i LINK PN IO can be integrated by means
of the PROFINET GSD file in the engineering tool (e. g. for
STEP 7 V5.4 SP2 and lower or for non-Siemens engineering
tools).
