The new Profinet ready wireless interface module enables the higher IP rated ET200pro distributed I/O system to communicate via Industrial Wireless LAN.
The IM154-6 PN HF IWLAN module can be operated on an Industrial Wireless LAN Access Point in a 2.4 GHz or 5 GHz IWLAN radio network with maximum data rates of up to 54 Mbit/s.
It enables the ET 200pro system to be employed for applications where a wired solution could only be implemented at high cost due to wear and tear, separation and inaccessibility.
Some possible areas of application are:
- Driverless transport systems
- Warehouse logistics
- Goods transport
- Electrical trolley conveyors
- Building management
- Service applications
The IM 154-6 PN HF IWLAN interface module communicates via Industrial Wireless LAN Access Points with PROFINET I/O controllers acc. to IEC 61158 standard.
Design
The IM 154-6 PN HF IWLAN interface module consists of:
- An interface unit (IWLAN radio card; compatible with IEEE 802.11a/h/b/g and IEEE 802.11e/i), and
- A connection unit
The interface unit and the connection unit are supplied together with the terminating module. The directly or separately mounted antennas are connected to the interface module via a screwed connection (R-SMA). The device name and the user and configuration data can be stored on a SIMATIC Micro Memory Card.
Features
In addition to a reliable radio link, the IM 154-6 PN HF IWLAN interface module provides the following features:
- IEEE 802.11b/ g/ a/ h for different frequency ranges
- IEEE 802.11e for Multimedia, Wireless Multimedia (WMM)
- IEEE 802.11i for Security
- Max. transmission speed (gross data rate) 54 Mbit/s
- Transmission method (Physical Layer)
- Direct Sequence Spread Spectrum (DSSS)
- Complementary Code Keying (CCK)
- Orthogonal Frequency Division Multiplexing (OFDM)
- Frequency bands / channels / transmission power:
2.4 – 2.4835 GHz / 13 / 20 dBm
5.15 – 5.25 GHz / 4 / 23 dBm
5.25 – 5.35 GHz / 4 / 23 dBm
5.47 – 5.725 GHz / 11 / 30 dBm
- Supported Industrial Wireless LAN services
- Optimized media access with Industrial Point Coordination Function (iPCF)
- Uninterrupted change of radio cell with Rapid Roaming (RR)
- Mechanisms against noise with Dynamic Frequency Selection (DFS) and Transmission Power Control (TPC)
- Two antennas can be used to optimize data transmission Security
A high degree of security is achieved with the WPA2/IEEE 802.11i mechanism. Here, modern procedures have been defined that control both a regular change of the complete 128-bit key, as well as access control (authentification) of subscribers. The Advanced Encryption Standard (AES) is used for data encryption.
Configuration
To configure the ET 200pro with IM 154-6 PN HF IWLAN (configuration and parameterization) you require the STEP 7 V5.4 + Service Pack 4 + HSP 0165 or higher configuration software.
