IO-Link执行器评估板为工业监测和电器提供交钥匙参考设计

ST has introduced an IO-Link reference design for industrial beacons and home-appliance alarms, delivered ready-to-use as a fully built board complete with protocol stack and application software.

意法半导体为工业信号和电气报警引入IO-Link参考设计，该参考设计作为一个完整的内置板交付，配有协议栈和应用软件。

The EVLIOL4LSV1 board leverages ST’s L6364Q dual-channel IO-Link transceiver to handle communications and the IPS4260L intelligent low-side power switch for driving the indicator lights. The board can be directly connected to signaling systems such as smart tower lights used in factory automation, funnel material alarms for quantity-remaining or urgency-level awareness, and other system warnings. It also provides a fast way to test the IPS4260L and L6364Q ICs and has a 4-pin M12 connector for an IO-LINK master and a 5-pin SWD connector for programming.

EVLIOL4LSV1板利用意法半导体的L6364Q双通道IO-Link收发器处理通信，并通过IPS4260L智能低边功率开关驱动指示灯。该板可直接连接到信号系统，如工厂自动化中使用的智能灯塔、用于漏斗中物料剩余量警报或紧急液位/物位感知，以及其他系统警告。此外，它还提供了用于快速测试IPS4260L和L6364Q IC的方法，并配有用于与IO-LINK主设备连接的4针M12连接器和用于编程的5针SWD连接器各一个。

An STM32G071CB microcontroller, which hosts the ST proprietary IO-Link demo stack and the application software, handles system control and diagnostics, communicating with the transceiver and low-side switch.

STM32G071CB微控制器中运行意法半导体专有的IO-Link演示协议栈和应用软件，可对系统控制和诊断进行处理，同时与收发器和低边开关进行通信。

The L6364Q transceiver is fully protected and supports standardized IO-Link communication speeds including 38.4kbit/s COM2 and 230.4kbit/s COM3. The transceiver can operate in single or multibyte mode, as well as in transparent mode delegating control of IO-Link communications to the microcontroller by a simple URT interface. The in-built protection ensures EMC immunity up to 2.5kVpk surge pulse/500Ω coupling without additional protection elements.

L6364Q收发器受具有保护功能，支持标准化的IO-Link通信速度，包括38.4kbit/s COM2和230.4kbit/s COM 3。收发器既可在单字节或多字节模式下运行，也可在透明模式下运行——通过简单的URT接口将IO-Link通信的控制委托给微控制器即可。内置保护功能可确保EMC抗扰度高达2.5kVpk浪涌脉冲/500Ω，无需额外的保护元件。

The IPS4260L low-side driver has four outputs for driving loads with one side connected to supply voltage, each individually controlled by a signal such as a digital microcontroller output. It has a wide operating-voltage range, from 8V to 50V, and the current for each output can be independently programmed from 0.5A to 3.0A. The IC integrates overload and overtemperature protection for each channel and provides open-load, overload, and overtemperature diagnostic signals to aid system management and enhance reliability. The reference design also features ST’s SMBJ30CA TVS (transient-voltage suppression) diode to withstand surge pulses with 2Ω coupling on the supply rail.

IPS4260L低边开关共有四个输出用于驱动负载，负载的另外一侧连接到电源电压，每个输出均由MCU的输出信号进行单独控制。其拥有8V到50V的宽泛工作电压范围，各输出的电流可在0.5A到3.0A之间可设置。该IC为各通道集成了过载和过热保护，并提供负载开路、过载和过热诊断信号，以帮助系统管理并提高可靠性。参考设计还具有意法半导体的SMBJ30CA TVS（瞬态电压抑制）二极管，可承受电源轨上2Ω耦合的浪涌脉冲。

The EVLIOL4LSV1 is available now from the eSTore and ST distributors for $23.
