The Ethernet Client Modules from the SCALANCE W-740 product line are designed for industrial applications as well as for inexpensive integration in cabinets or in devices. They provide a reliable radio link, which will transfer quickly from one Access Point to the next (roaming). In this manner, processes can be monitored and production failures through machine downtimes avoided. In addition, Industrial Wireless LAN (IWLAN) can be used in time-critical applications associated with production automation (PROFINET IO) or for safety-related signals (PROFIsafe).

The Client Modules with the high degree of protection IP65 and the extended temperature range from -20 to +60 °C make these suitable for use in the food and beverages industry (cooling technology) and in logistics. SCALANCE W products are silicone-free and can therefore also be used in paint shops.

The Client Modules in degree of protection IP30 are especially suitable in the automotive industry for use in automated guided vehicle systems or suspended monorails.

When using the RCoax cable (radiating cable), operation is particularly reliable in conveying technology and all track applications (e.g. warehouse stacking machines).

Application examples:

• Automated guided vehicle systems (AGVS) and suspended monorails;
  prevention of wear and high flexibility in the choice of route thanks to wireless transmission of data to the vehicles
• Crane;
  high flexibility through access to data communication with the moving unit independent of the location
• Mobile control console;
  reliable intervention in the process thanks to data communication over IWLAN with mobile units (e.g. Mobile Panel 277F IWLAN); the number of operator panels is therefore determined by the number of personnel and no longer by the number of control desks.
• Wireless access to field devices for configuration and testing without the need for time-consuming modifications in the control cabinet
• Online access to service and maintenance drawings;
  Immediate updating of the measures performed in the system over IWLAN;
  Optimized processes and reduced error ratios thanks to online information regardless of the location of the machine
• Communication with moving nodes (e.g. mobile controls and devices), storage and retrieval machines, conveyor systems, conveyor belts, rotating machines, trucks
• Wireless coupling of communication segments for fast commissioning or for cost-effective networks in which cable routing would be extremely expensive (e.g. on public roads, rivers, lakes, train lines)
