Getting started with the X-NUCLEO-PLC01A1 industrial input/output expansion board for STM32 Nucleo

Introduction The X-NUCLEO-PLC01A1 is an expansion board designed to build basic PLC (programmable logic controller) applications. Plugged onto any STM32 Nucleo board through the Arduino UNO R3 connectors, it results in a compact industrial PLC capable of managing eight analog inputs and eight outputs through the SPI peripheral. The 24 V power supply makes it possible to manage industrial range inputs (i.e. sensors, valves) and outputs (i.e. lamps, alarms). The board is not intended to utilize all of the features of the CLT01-38SQ7 and the VNI8200XP devices. The X-NUCLEO-PLC01A1 embeds diagnostics and fault LEDs, as well as activity status LEDs for all channels in input and output. Compatibility with the STM32 Nucleo family of boards as well with other expansion boards is assured by the use of Arduino UNO R3 connectors, while the board schematics, bill of materials, Gerber files, drivers and firmware are available for download on www.st.com.

UM1918 Description

1 Description

To perform industrial IO (input/output) management, the X-NUCLEO-PLC01A1 is equipped with CLT01-38SQ7 and VNI8200XP ICs. Both devices on the board work through the SPI peripheral, and as such any STM32 Nucleo board to which it is connected can implement an industrial PLC application. Both devices support 8- and 16-bit SPI interfaces for device command and control diagnostics. The board is equipped with a digital isolator in order to assure SPI safe operation between the X-NUCLEO-PLC01A1 and the STM32 Nucleo board. The VNI8200XP includes advanced protection and fault detection features. CLT01-38SQ7 provides protection and isolation in industrial operating conditions as well as an “energy-less” status indication for each of the eight input channels, with minimal power consumption. It is suited for situations that require test standards IEC61000-4-2 8 kV and 15 kV to be met. Both the CLT01-38SQ7 and the VNI8200XP are designed to meet the most common industrial requirements (i.e. IEC61000-4-2, IEC61000-4-4, IEC61000-4-5 or IEC61131-2). For more thorough evaluation of the individual products, it is recommended to refer to their single respective evaluation boards, available on st.com.

Features UM1918

4/16 DocID028079 Rev 1

2 Features

The X-NUCLEO-PLC01A1 is a ready-to-use PCB (printed circuit board) including:

8x input with CLT01-38SQ7, high-speed protected digital termination array

8x output with VNI8200XP, high-side solid state relay

Status LEDs: Fault, Thermal, Power

IO (input/output) activity LEDs

24 V power supply

Compatible with Arduino UNO R3 connector

A reverse polarity diode is part of the input stage. As a result, when a 24 V supply is applied to the input connector, the supply voltage on the CLT01-38SQ7 device is given by: Vsupply – VFWD, where VFWD is the voltage applied on the reverse diode.

Capacitors C15 and C19 are not mounted. They are only needed to perform common mode surge tests.

3 Hardware and layout description

The X-NUCLEO-PLC01A1 board adds to any STM32 Nucleo board the capabilities of a compact industrial PLC with 8 inputs and 8 outputs. This is possible through SPI management as depicted in the functional block diagram below.

4 X-NUCLEO-PLC01A1 assembly drawing

The main components of the board are specified in the drawing below. The X-NUCLEO-PLC01A1 is shaped in such a way as to allow easy access to the STM32-Nucleo board when both boards are connected. Input and output channels are accessible through the screw connectors placed on the low side of the X-NUCLEO-PLC01A1 (connectors J8 and J10, respectively), and each channel is associated to one LED in order to indicate its activity and status. Another three LEDs are provided on the board to provide status and diagnostic information for the VNI8200XP device (temperature warning, fault and Power Good detection). The SPI selector allows the CLT01-38SQ7 device to be managed in 8-bit or 16-bit bus mode.

5 X-NUCLEO-PLC01A1 board powering and startup

The following steps must be followed to run the X-NUCLEO-PLC01A1:

1. Plug the X-NUCLEO-PLC01A1 onto a STM32 Nucleo board 2. Connect the STM32 Nucleo board to a PC via a standard Type A / mini B USB cable 3. Download the firmware on the STM32 microcontroller hosted on the STM32 Nucleo

board 4. Supply 24 V to the X-NUCLEO-PLC01A1 board through the J8 connector 5. The X-CUBE-PLC1 demonstration firmware is ready to run: connect any of the 8

inputs on the J8 connector to see the corresponding output on the J10 connector capable of driving a load (i.e. short-circuit input “x” with the 24 V and connect the corresponding output “x” to a load).
