STMicroelectronics STEVAL-IDP004V2

Overview

STEVAL-IDP004V2 from STMicroelectronics is a 4-port IO-Link master evaluation board built around the STM32F205RB ARM Cortex-M3 MCU (120 MHz, 128 KB Flash) and four L6360 IO-Link transceivers. It supports full IO-Link v1.1 physical layer communication via M12 connectors (max 20 m cable), includes RS-485, CAN, and USB interfaces, and implements on-board reverse polarity protection and DC-DC power management for industrial 32 V supply.

For engineers reviewing the STEVAL-IDP004V2 datasheet, STEVAL-IDP004V2 pinout, STEVAL-IDP004V2 application, or STEVAL-IDP004V2 equivalent, this board serves as a validated multi-port IO-Link master reference design compliant with IEC 61000-4-2/4/5, enabling rapid prototyping of industrial sensor networks, smart factory gateways, and distributed I/O systems.

Technical Context

The board implements asynchronous serial IO-Link communication using four independent L6360 transceivers, each connected to the STM32F205RB via dedicated I²C bus segments with individual slave addresses. Each port supports C/Qi (data) and C/Qo (output) signaling, EN_L+ control, and IRQ-driven event notification.

Hardware-level protocol support includes integrated RS-485 transceivers (ST3485DE/RE), CAN transceiver (MAX3051), USB 2.0 full-speed interface (via ST-LINK/V2), and a 1.2 mH/400 mA DC-DC converter (L7986A) delivering regulated Vdd for transceivers - all laid out to meet IEC 60947-5-2 and EMC immunity requirements.

FAQ

Does STEVAL-IDP004V2 include the full IO-Link protocol stack?

No. The board ships with a pre-programmed TEConcept GmbH IO-Link stack featuring read-out protection and a 10,000-minute time-limited license. Flashing STSW-IO-LINK (physical layer only) overwrites the stack irreversibly - no recovery option exists once overwritten.

What are the supported IO-Link communication modes?

The board supports IO-Link v1.1 Class A and Class B operation across all four ports, including COM1 (4.8 kbps), COM2 (38.4 kbps), and COM3 (230.4 kbps) speeds, with configurable C/Qi/C/Qo timing per port via STM32F205RB register control.

Can the RS-485 and CAN interfaces be used simultaneously with IO-Link operation?

Yes. RS-485 (via ST3485DE/RE) and CAN (via MAX3051) operate independently from the IO-Link transceivers and share no signal resources with the L6360s or I²C buses - enabling concurrent diagnostics, configuration, or supervisory messaging alongside real-time IO-Link data exchange.

Is external power required for the IO-Link slave devices?

No. Each M12 port delivers L+ (24 V nominal, up to 32 V) and L− lines directly from the board's regulated DC-DC output, capable of supplying up to 200 mA per port - sufficient for powering standard Class A and most Class B IO-Link slaves without auxiliary power.
