Development kit eases IO-Link system design

Infineon Technologies AG has released a design evaluation kit for development of communication systems supporting the IO-Link V1.1 standard.

Based on the company’s 16-bit XE166 and 8-bit XC800 microcontrollers can produce designs that support up to eight IO-Link channels on the master with a FIFO buffer for each channel.

It has been developed in cooperation with experienced partners in industrial automation – Hitex Development Tools, Technologie Management Gruppe, supplier of IO-Link software stack, and the Zentrum Mikroelektronik Dresden AG (ZMDI), a provider of IO-Link PHY devices. The Infineon IO-Link evaluation kit allows equipment manufacturers to evaluate the functionality of a complete IO-Link-based master-device combination.

The kit includes a USB stick as the XE164-based master node including physical transceiver PHY and supporting four IO-Link channels, a single 8-bit XC822 based device node, cabling, demos and documentation. Additional projects using the 8-bit XC800 as a device have also been developed with the partners HMT microelectronic, supplier of IO-Link physical transceivers and IP, and MESCO Engineering, supplier of IO-Link device software stack. 

The master node of the Infineon IO-Link solution is based on the XE164, a member of the XE166 16-bit microcontroller family. The XE166 real-time signal controllers offer 32-bit performance on 16-bit devices, with up to 100 MIPS and integrated MAC unit with complete DSP library.

The scalable family include devices with flash sizes from 128KB to 1600KB and packages from 64-pin to 176-pin. Up to four independent pulse width modulation units and fast analog to digital converters with 600ns conversion time are part of the powerful peripheral set.

The intelligent device node of the IO-Link kit is based on the XC822, one
of the latest members of the scalable XC800 8-bit MCUs. With the XC800 family, Infineon has combined an 8051-core with embedded flash memory up to 64Kbyte.
To reduce system costs, features such as oscillator, voltage regulator, EEPROM
and supervisory circuits are integrated.

Different flash sizes, scalable peripherals and innovative features like an multiply division unit co-processor make it easy to select the right product for a dedicated application. The peripherals include a Capture/Compare Unit for flexible PWM generation and an enhanced fast AD converter for precise measurement and hardware synchronization to PWM.

IO-Link is a standardized point-to-point communication system that simplifies integration of sensors and actuators into factory automation systems. It offers various benefits for end users including easier and less expensive cabling, remote diagnostics and configuration.

 

An IO-Link system consists of an IO-Link master and one or more IO-Link devices (sensors or actuators). The IO-Link master provides the inter¬face to the PLC (Programmable Logic Controller) and controls the communication between connected IO-Link devices.

IO-Link enables a robust communication with built-in error detection and easy integration into well-established field bus systems with reduced and unshielded cabling. As an open interface, IO-Link can be integrated into all common field bus and automation systems.
