IO-Link is an open protocol defined by IEC 61131-9 as an international standard. It is a serial communication protocol that connects sensors and actuators to remote I/O or PLC in factory automation. With demand increasing for IoT, demand for IO-Link is also growing for unified management of big data from sensors and actuators to upper layers. Renesas provides an application note, sample program, sample software including system configuration and block diagrams, and protocol stack for evaluation, enabling users to realize measurement, signal processing and IO-Link communication with a single chip.

RA2E1 IO-Link Pressure sensor solution

This solution is the combination of ultra small and low power consumption 32-bit MCU RA2E1 and ZSSC3240 kit (Sensor Signal Conditioner) realize pressure measurement, signal processing through IO Link communication.

Key Features

  • 32bit MCU RA2E1 48MHz with Arm Cortex-M23 board supports ultra-small size and low power consumption, contributing BOM cost reduction and system miniaturization.
  • ZSSC3240 achieves high accuracy of sensor correction with up to 24-bit A/D converter resolution.
  • Providing to check the device information, monitor the measurement data, parameter setting from IO-Link tool on user’s PC through IO-Link master. Enables to control LED ON/OFF based on measurement data to evaluate easily the benefits of IO-Link communication.
  • Contains IO-Link stack* developed by TMG, which can be suitable for initial evaluation.
  • Photocoupler, power supply ICs, IO-Link PHY and other peripheral components are also available from Renesas.

RX23E-A IO-Link Temperature Sensor Solution

This single-chip solution uses the 32-bit RX23E-A microcontroller with built-in high-precision analog front-end (AFE) to measure temperature, process sensing and signals, and control IO-Link communications via a ZIOL2401 IO-Link PHY chip.

Key Features

  • View RX23E-A RSSK information, and monitor temperature measurement and parameter settings using the IO-Link tool on a PC via a master device.
  • Includes demo that controls LED on/off control based on temperature measurement value set in the IO-Link tool, as an example of an application transmitting an indicated value from an upper layer to a temperature measurement device. Easily try out two-way communication, one of the merits of IO-Link.
  • Contains IO-Link stack developed by TMG, which can be used for evaluation purposes.
  • Sensor signal isolating photocoupler/optocoupler, power supply ICs, and other peripheral components ideal for temperature measurement devices are also available from Renesas.
