IO-Link Single Chip Controller
Increased productivity, interrupted plant operation, low maintenance and commissioning, are some of requisites for modern factories. Machine builders need always-on sensors which can be operated remotely, while preserving a cost effective installation infrastructures. To answer these needs, a worldwide consortium of sensor and semiconductor manufacturers have developed IO-Link, a new standardised communication protocol for smart industrial sensors networking.
IO-Link is a fieldbus independent serial digital communication protocol used for intelligent sensors and actuators in industrial automation systems. The specification is registered under the IEC (International Electrotechnical Commission) as IEC 61131-9.
IO-Link offers the following key advantages:
・Adaptable integration into existing fieldbus or Industrial Ethernet environments.
・Remote process, parameter and diagnostics data management.
・Backward compatibility with digital switching sensor interfaces.
・Communication over standard unshielded 3-wires sensor cables.
As a member of the IO-Link Consortium and a premier supplier of advanced semiconductor solutions, Renesas Electronics developed new single-chip solutions for IO-Link master applications, based on close cooperation with its business partners ELMOS Semiconductor AG and TMG-Karlsruhe. The master solution is the world's first single chip device to integrate a complete two-channel master transceiver along with the master software stack operating on the CPU core. The concept allows the development of scalable solutions when combining several of the IO-link master chips. It significantly reduces the required board space for these applications as well as the overall design cost and complexity.
