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 startup 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 (from product version 4 / firmware
version 2.2) and for AS-Interface with 30 V voltage
•
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 display of
the operating state and readiness for operation of all con-
nected AS-Interface slaves
•
Six pushbuttons for starting up and testing the AS-Interface
line directly on the IE/AS-i LINK PN IO
•
LED display of the operating state of PROFINET IO and
AS-Interface
•
Integrated 2-port switch (RJ45 socket) for connection to
Industrial Ethernet
•
Small mounting depth thanks to recessed plug mounting
•
Operation without fans and batteries
Functionality
Communications
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 with full expansion: 62 bytes of input data
and 62 bytes of output data in which the I/O data of the con-
nected AS-Interface slaves (standard and A/B slaves) of an
AS-i line are stored.
•
As double master, double the number of bytes
•
Optional additional I/O bytes for data from analog slaves
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 IO controller.
The integrated evaluation of analog signals is just as easy as
access 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-Interface 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. Internet 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
entering the connection parameters (e. g. IP address), keeping
downtimes to a minimum in the event of a fault.
Diagnostics
The following diagnostics is possible using the display and
control keys, web interface or STEP 7:
•
Operating state of the IE/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
•
The reporting of diagnostic events is optionally possible via
E-Mail or SNMP Trap. The integrated diagnostic buffer saves
the events including time stamp.
Notes on safety:
The use of this product requires suitable protective measures
(e.g. network segmentation for IT security among others)
in order to ensure safe plant operation, see

.
Configuration
The IE/AS-i LINK PN IO is configured as follows:
•
STEP 7 V5.4 or higher is required for configuring the full
functional scope of the
IE/AS-i LINK PN IO. With STEP 7 configuring the AS-Interface
configuration can be uploaded in STEP 7 V5.4 SP2 and higher.
Furthermore, AS-Interface slaves from Siemens can also be
conveniently configured in HW Config (slave selection dialog).
•
Alternatively, IE/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, TIA portal, or for non-Siemens
engineering tools).
