The IE/AS‑i Link PN IO is a compact router between PROFINET 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
• 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
• Vertical integration (standard web interface) through Industrial Ethernet
• Supply via AS-Interface cable or with 24 V DC
• Suitable for AS‑i Power24V and 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

Note:

As an alternative to the IE/AS‑i Link PN IO, a powerful network transition can be set up between PROFINET and AS‑Interface by combining the CM AS‑i Master ST and F‑CM AS‑i Safety ST modules in an ET 200SP station (for safety-related applications), see "Masters" в†’ "Masters for SIMATIC ET 200".

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 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 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

Communication

The IE/AS‑i Link PN IO allows a PROFINET IO controller to cyclically access the I/O data of all slaves of a subordinate AS‑Interface segment. Also supported are the expanded slave types with higher I/O data volume according to AS‑i Specification 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 connected AS‑Interface slaves (standard and A/B slaves) of an AS‑i line is stored
• Double the number of bytes as double master
• 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 additionally able 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
• State 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 diagnostics access through Ethernet using a standard browser
• 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

In order to protect plants, systems, machines and networks against cyber threats, it is necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial security concept. Siemens products and solutions only represent one component of such a concept.

Configuration

The IE/AS‑i Link PN IO is configured as follows:

• With STEP 7 (classic) V5.4 or higher: When configuring in STEP 7, 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 in the engineering tool by means of the PROFINET GSD file (e.g. for TIA Portal, for STEP 7 versions V5.4 SP2 and lower, or for non‑Siemens engineering tools).

Please observe the configuration notes in the TIA Portal, see https://support.industry.siemens.com/cs/ww/en/view/109483764
