Basics
What is Industrial Wireless LAN?
In addition to data communication in accordance with the IEEE 802.11 standard, the
SIMATIC NET Industrial Wireless LAN provides a number of enhancements which offer
significant benefits for industrial customers. IWLAN is particularly suitable for demanding
industrial applications that require reliable wireless communication. This is supported by the
following properties:
● Automatic roaming when the connection to Industrial Ethernet is interrupted (Forced
Roaming)
● Cost savings generated by using a single wireless network for reliable operation of a
process with both process-critical data (alarm message, for example) and non-critical
communication (service and diagnostics, for example)
● Cost-effective connection to devices in remote environments that are difficult to access
● Predictable data traffic (deterministic) and defined response times
● Cyclical monitoring of the wireless link (link check)
Objectives and advantages of Industrial Wireless LAN
Wireless data transmission achieves the following objectives:
● Seamless integration of PROFINET devices into the existing bus system via the wireless
interface
● Mobile use of PROFINET devices for different production-linked tasks
● Flexible configuration of the system components for fast development in accordance with
customer requirements
● Maintenance costs are minimized by savings in cables
