Wireless technology has moved on in recent years to the point where there are few applications where it cannot be used. The obvious requirement for wireless technology is where it is too costly (cable and copper costs) or where it is impossible to run cables.
Examples are:
- Between buildings
- Across roadways
- Airport runways
- Across water
- Across third party property
- Escalators/Lifts
- Cranes
- Long distance cable runs (Ethernet 100 metres limitation)
The list goes on and on.
Wireless also fits where the requirement is likely to change such as a production line expansion or a modular system that requires regular changeover for different products. It may also just be that wireless provides a convenient access point into your application or system. Of course there is not just one wireless technology, there is a choice to suit your application and below are some examples.
This is a simple solution with no configuration required. 16 digital inputs to 16 digital outputs / 2 analogue in to 2 analogue outputs – both ways. A simple wireless solution up to around 100 metres.
Keeping it simple, this system has a quick set up system using the thumb wheels on the front of the I/O and radio 
units and can be used in various topologies. It can be used for digital/analogue multiplex and / or serial communications over distances of up to 30km.
Ethernet /WLAN & Bluetooth
Probably the most requested solution is Wireless Ethernet. Solutions include Profisafe over bluetooth (Ethernet). It has simple local access point and /or client arrangements. You can also have long distance WLAN including roaming and cluster management for factory floor implementation.
Wireless safety example using either WLAN or Profisafe over Bluetooth
So that’s why you should go wireless!
