MAXREFDES145#: 8-Channel IO-Link Master

MAXREFDES145

参考设计免责声明 参照  重要声明和免责声明  涵盖参考设计和其他Maxim资源

描述

The MAXREFDES145# is a fully IO-Link®-compliant, 8-port IO-Link master reference design. This design uses TEConcept's IO-Link master stack and is both an IO-Link master reference design as well as an IO-Link sensor/actuator development and test system. Eight IO-Link ports allow for simultaneous testing of up to eight different sensors (or actuators). The reference design has eight robust female M12 connectors, the most common connector used for IO-Link, and ships with two IO-Link cables to quickly connect to IO-Link compatible sensors and actuators. An AC-to-DC (24VDC/1A) power-supply cube is capable of providing at least 125mA simultaneously to each port and more when fewer ports are unused. A USB 2.0 Type B connector allows for quick connectivity to a Windows® PC.

The easy-to-use TEConcept Control Tool (CT) GUI software with IODD file import capability makes the MAXREFDES145# a must-have for any company or engineer serious about developing IO-Link products.

Introduction

IO-Link is the first open, field bus agnostic, low-cost, point-to-point serial communication protocol, used for communicating with sensors and actuators, that has been adopted as an international standard (IEC 61131-9). IO-Link standardizes interoperability of industrial equipment from all over the world. IO-Link can function directly from the PLC or can be converted from all standard field busses to IO-Link through a gateway, quickly making it the defacto standard for universally communicating with smart sensors and actuators.

IO-Link is a single-drop digital communication interface (SDCI), which means there can only be one sensor or actuator per port. The 3-wire protocol is also backwards compatible with binary sensors and actuators that use standard input output (SIO). IO-Link device descriptor (IODD) files completely define the device and eliminate manual parameterization.

The MAXREFDES145# design utilizes four MAX14819 dual-channel Maxim Integrated IO-Link master transceivers, two on-board digital isolators, the efficient industrial MAX15062B step-down converter, an FTDI USB-to-SPI interface and an STMicroelectronics 32-bit ARM Cortex® M4 microcontroller (STM32F4) utilizing TEConcept’s CT Tool software and IO-Link master stack. Figure 1 shows the system block diagram.

Detailed Description of Hardware

The MAXREFDES145# IO-Link master consists of 4 main blocks: four dual-channel MAX14819 IO-Link master transceivers, two digital isolators for the SPI interface, a microcontroller, and a USB connection as shown in Figure 1.

The MAX14819 IO-Link master transceivers are IO-Link version 1.1.2 physical layer compliant. These transceivers feature integrated 5V linear regulators, configurable C/Q outputs (push-pull, high-side, or low-side) with configurable output drive capability, auxiliary digital inputs, and reverse-polarity/short-circuit protection.

An STM32F4 ARM Cortex M4 microcontroller in a 10mm × 10mm, 64-pin LQFP package provides system control. A universal serial bus (USB) port is implemented using the FTDI FT2232 USB-to-SPI transceiver and driver. An on-board MAX15062B high-voltage, synchronous step-down converter provides power to the STM32F4 microcontroller from the 24V supply.

Two digital isolators, the 4-channel MAX14931F and the 2-channel MAX12931B, protect the USB interface from high-voltage and large ground differentials that can occur when the MAX14819 master transceivers are connected to IO-Link peripherals. All communication between the USB port/PC and the SMT32F4 microcontroller passes through these isolators.

A stand-alone SPI header (J3) is available on the MAXREFDES145# to allow the user to bypass the USB interface and directly communicate with the STM32F4 using an external SPI master. J3 is connected to the isolated side of the board and all digital communication from the external master to the STM32F4 goes through the isolators. An external 3.3V logic supply to power the isolators is required when using J3.

High-level protection transient voltage suppressor (TVS) diodes at each of the eight IO-Link interface ports and at the power supply inputs provide surge and reverse-polarity protection for each master transceiver on the MAXREFDES145#.

Additionally, power and status LEDs (for each channel) provide quick visual confirmation that the board is working and communicating.
