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.

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 possible to connect them in a different power supply than 24 V.

Inputs: (6x) Analog (0-10Vdc) / Digital (5-24Vdc) configurable by software 

Know more about Analog Input.

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 possible to connect them in a different power supply than 24 V.
Digital Inputs provides us PNP input. 

Inputs: (6x) Digital Isolated (5-24Vdc), one of them can work like interrupt INT (7-24Vdc).

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. 

Interrupt	Pin Arduino Mega	Pin M-Duino
INT1	3	I0.6/INT1

In this example we activate INT1 using pin I0_6 from M-duino board. When there’s a change

#define INTERRUPT I0_6 //other pins: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;
}
