In this post it will be seen a review of the PLC Arduino ARDBOX 20 I/Os Analog HF Modbus.
The guide of the PLC Arduino ARDBOX 20 I/Os Analog HF Modbus on our website is already uploaded into the 7.1 version. The User Guide now is for the HF version, so it exists now the possibility of taking all the information of the PLC Arduino ARDBOX 20 I/Os Analog HF Modbus from there.
It will be shown a little introduction of this product, that shows the main features of it:
9x Analog (0-10Vdc) / Digital (5-24Vdc), configurable by software.
1x Digital PNP (opto-isolated)
The 9x Analog/Digital pins are configurable by software. These pins are named from (I0.1-I0.9). To use it
as a Digital pin it must be read by the software using DigitalRead(). To use it as analog you need to use
10x Digital isolated (5-24vdc)/6x of 10x, PWM (5-24 Vdc), configurables by switch
7x of 10x, Analog 0-10V output, configurables by Switch
The 6x PWM pins are Q0.0 – Q0.6. PWM is the Pulse-Wave-Modultation. It is a modulation technique used to
encode a message into a pulsing signal.
The 7x Analog are A0.0-A0.6. These pins are shared with the PWM. In the right zone there is a switch to put
these X0.0-X0.6 as digital or analog
1x USB Port
It is the most common way to talk with the Arduino Board from the computer. It is also by default the fastest way to
upload a code into the Arduino.
1x RS-485 Half / Full Duplex (Modbus RTU)
Using the switch of the right zone it can be configured for a Half or Full Duplex. The difference between this two
modes is that the Half Duplex can only speak or listen, one at the same time. Instead the Full Duplex can speak
and listen at the same time.
Modbus is an standard protocol of the Industrial Communication. It is really used because it is been designed for
industrial application, it is public, free and it is easy to implement.
is a multi-master, multi-slave, packet switched, single-ended, serial computer bus. It is widely used for attaching
lower-speed peripheral ICs to processors and microcontrollers in short-distance, intra-board communication.
Serial Peripheral Interface (SPI) is a synchronous serial data protocol used by microcontrollers for communicating
with one or more peripheral devices quickly over short distances. It can also be used for communication between
