The point-to-point connection is set up between an IO-Link master and an IO-Link device (sensor or actua- tor) using an unshielded three-core cable. IO-Link is faster and easier to install than other monitoring and control approaches such as Ethernet. Another advantage is that the detection and resolution of false sensor settings are much more straightforward to detect, isolate, and resolve. IO-Link is a vendor-neutral solution. That means that mod- ules and devices from different suppliers can smoothly be attached to the network. This feature allows for extensions or modifications, such as adding more sensors very quick- ly. Connecting additional sensors will provide more data enabling enhanced diagnostics, monitoring, and control. ST/Industrial Sensing Solutions 29 SIGFOX asset tracking application Sigfox is a subscription-based low-power wide-area net- work (LPWAN) service based on sub-1GHz frequencies. Sigfox allows connectivity directly to telecom infrastruc- ture and in-turn to the cloud. It can give connectivity over several kilometers. Sigfox can be used to send sensor data to the cloud for applications such as asset tracking. It is a low data rate technology, and it is not expected to replace direct control connectivity options such as BLE and RF sub- 1GHz direct peer-to-peer connection.
