Description
The X-NUCLEO-PLC01A1 is an industrial
input/output evaluation board which expands the
STM32 Nucleo board functionality with a PLC
(programmable logic controller) function subset. It
is compatible with the Arduino UNO R3
connector layout and is designed around
VNI8200XP (solid state relay) and CLT01-38SQ7
(octal digital termination array). The X-NUCLEO-
PLC01A1 interfaces with the STM32 MCU via the
SPI peripheral. Moreover, it is equipped with a
set of diagnostic and activity LEDs to facilitate
application debugging. It can accept other
STM32 plug-on expansion boards to further
extend the STM32 Nucleo board functionality.
The X-NUCLEO-PLC01A1 allows the rapid
evaluation of the ICs on board performing a basic
set of PLC operations in conjunction with the X-
CUBE-PLC1 software package. X-NUCLEO-
PLC01A1 is not intended to evaluate the single
devices at their full specifications. 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, featuring minimal power
consumption; it is designed for situations that are
required to pass the IEC61000-4-2 8 kV and
15 kV test standards. 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); to eveluate them further, refer to
