説明

The MAXREFDES165# is a fully IO-Link®-compliant, 4-port IO-Link master reference design. This design uses the TMG TE IO-Link master stack and is both an IO-Link master reference design and a development and test system for IO-Link sensors/actuators. Four IO-Link ports allow for simultaneous testing of up to four different sensors (or actuators). The reference design has four robust female M12 connectors—the most common connector used for IO-Link—and ships with an IO-Link cable for connecting quickly to IO-Link compatible sensors and actuators. An AC-to-DC (24VDC/1A) power supply is capable of providing at least 250mA to each port simultaneously, and more when fewer ports are used. A USB 2.0 Type B connector allows for quick connectivity to a Windows® PC.

IO-Link is the first open, field-bus agnostic, low-cost, point-to-point serial communication protocol for communicating with sensors and actuators. 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 through a gateway, quickly making it the de facto standard for universal communication with smart sensors and actuators.

IO-Link is a single-drop digital communication interface (SDCI), which means it supports only one sensor or actuator per port. The three-wire protocol is also backward compatible with binary sensors and actuators that use standard inputs and outputs. IO-Link device descriptor (IODD) files completely define the device and eliminate manual parameterization.

The MAXREFDES165# design utilizes two MAX14819 dual-channel Maxim Integrated IO-Link master transceivers, an on-board digital isolator, the efficient industrial MAX15062AATA+ step-down converter, a FTDI USB-to-SPI interface, and a STMicroelectronics® 32-bit Arm® Cortex®-M4 microcontroller (STM32F4) utilizing TMG TE’s IO-Link Device Tool software and TMG TE’s IO-Link master stack. Figure 1 is the system block diagram of the MAXREFDES165# design.

Detailed Description of Hardware

The MAXREFDES165# IO-Link master comprises four main blocks:

  • Two dual-channel MAX14819 IO-Link master transceivers
  • A MAX14931 digital isolator for the SPI interface
  • A microcontroller
  • A USB connection (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 x 10mm, 64-pin LQFP package provides system control. A USB port is implemented using the FTDI FT2232 USB-to-SPI transceiver and driver. An on-board MAX15062A high-voltage, synchronous step-down converter provides power to the STM32F4 microcontroller from the 24V supply.

A digital isolator, the four-channel MAX14931F protects 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 this isolator.

A stand-alone SPI header (J3) is available on the MAXREFDES165# to allow the user to bypass the USB interface and communicate directly 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 four IO-Link interface ports and at the power supply inputs provide surge and reverse-polarity protection for each master transceiver on the MAXREFDES165#.

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

Figure 2 shows the box contents for the MAXREFDES165# reference design.

Detailed Description of Software

TMG IO-Link Device Tool Windows-compatible software features IODD file import capability, connects to a PC through USB, and is available to download from the Design Resources tab of the MAXREFDES165# webpage. The TMG IO-Link Device Tool software is shown in Figure 4, and a complete step-by-step Quick Start guide is also downloadable from the Design Resources tab.

Note: The MAX14819 can be configured to operate with a UART interface (within the microcontroller) or by using the integrated framers on the IC. The default stack that ships with the MAXREFDES165# is the UART version. If you require the Framer version please contact the factory.
