Programmable Logic Controller Library

Library to handle the X-NUCLEO-PLC01A1 Programmable Logic Controller Expansion Board based on the VNI8200XP (solid state relay) and CLT01-38SQ7 (octal digital termination array) components.

Information

For further details on VNI8200XP (Octal high side smart power solid state relay with serial/parallel selectable interface on chip) please refer to ST's web site.

For further details on CLT01-38SQ7 (High speed digital input current limiter) please refer to ST's web site.

SPI configuration

Pin D3 and D13 providing the SPI serial clock are short-circuited in the X-NUCLEO-PLC01A1 Expansion Board.

Please be aware that you may not drive the base board LED if it is connected to pin D13 (as it happens on STM32 Nucleo boards) or D3, otherwise you will get a conflict.

Platform compatibility

  • STM32 NUCLEO boards have been tested with the default configuration provided by the HelloWorld_PLC01A1 example. 

return DSPI_HAL_ReadData(spi_address[obj->instance]);

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 base board
  2. Connect the base board to a PC via a standard Type A / mini (or micro) B USB cable
  3. Download the firmware on the MCU hosted on the base board
  4. Supply 24 V to the X-NUCLEO-PLC01A1 board through the J8 connector
  5. The HelloWorld_PLC01A1 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).
