Initial Installation

ARDUINO IDE

Arduino IDE is the Original platform to program Arduino boards. This cross-platform application is available on Windows, macOS and Linux and under the GNU General Public License. Arduino IDE supports C and C++ code structuring. Industrial Shields recommend using Arduino IDE to program Arduino Based PLC’s, but any Arduino compatible software are compatible with Industrial Shields Controllers.

Apart from that, Industrial Shields bring the possibility to select your Arduino based PLC into your Arduino IDE and compile your sketches for
the different PLC’s.

Inputs & Outputs

ANALOG INPUTS

Voltage variation  between  –Vcc (or GND)  and  +Vcc, can take any value. An analog input provides a coded measurement in the form of a
digital value with an N-bit number.  In Digital and Analog I/O there’s self insulation, so its posible to connect them in a different power supply
than 24 V.  

Inputs: (6x) of 10x, Analog (0-10Vdc) configurable by Software.


TYPICAL CONNECTION

DIGITAL INPUTS

Voltage variation  from  –Vcc (or GND)  to  +Vcc, with no intermediate values. Two states: 0 (-Vcc or GND) and 1 (+Vcc).  In Digital and Analog I/O there’s self insulation, so its posible to connect them in a different power supply than 24 V.  

Inputs: (10x) Digital (5-24Vdc).

TYPICAL CONNECTION


- Digital Isolated Input


 

- Digital No Isolated Input

INTERRUPT INPUTS

Interrupt Service Rutine.  A mechanism that allows a function to be associated with the occurance of a particular event. When the event
occurs the processor exits immediately from the normal flow of the program and runs the associated ISR function ignoring any other task. 


Inputs:  (1x) Interrupt Inputs (5-24Vdc). “Can work like Digital Input (24Vdc)”.

EXAMPLE

In this example we activate INT0 using pin I0_0 from M-duino board. When there’s a change  

#define INTERRUPT I0_0 //other pins: I0_1, I0_6, I2_6, I2_5, I1_6, I1_5 (M-Duino) I0_0, I0_3, I0_2, I0_1 (Ardbox)

volatile bool state = false;

void setup() {
  pinMode(INTERRUPT, INPUT_PULLUP);
  attachInterrupt(digitalPinToInterrupt(INTERRUPT), function_call_back, CHANGE);
}

void loop() {
  if (state == true){
    Serial.println("Interrupt activated");
    state = false;
  }
}

void function_call_back(){ //Change led state
  state = true;
}
