12. Page 12 4. Software interface Industrial Shields PLC are programmed using Arduino IDE, which is a software based on the C language. They can also be programmed using directly C but it is much easier working with Arduino IDE as it provides lots of libraries that helps in the programming . Furthermore Industrial Shields provides boards for programming the PLCs much easier. Basically it is no needed to define the pins and if that pins are inputs or outputs. Everything is set up automatically if using the boards. In order to install Indust rial Shields boards, these are the steps that must be followed. Requirements: Arduino IDE 1.8.0 or above (better to have always the latest version). Steps: 1. Open Arduino IDE and g o to: “ File - > Preferences ” located in the top left corner. 2.

26. Page 26 I2C pins – SDA/SCL The I2C protocol is meant to work in a pull - up configuration. The I2C pins in the Arduino Leonardo are not pull - up, so in order to work with the I2C an external pull - up resistor is required. If it is meant to work as a GPIO at 5V, the switches must be set as I2C, (section 8). These pins are not stablished with a pull - up or a pull - down configuration. The state of these pins is unknown. If these pins must be used they require a pull - up or a pu ll - down configuration. The Arduino board allows the pins to be set in a pull - up configuration. If not it must be stablished an external pull - up or pull - down circuit in order to correctly work with these pins. SPI – MISO/MOSI/SCK These pins can only work as a 5V pins. As the Ardbox family does not implement the Ethernet protocol, these pins can always work as a 5V pins. These pins are not stablished with a pull - up or a pull - down configuration. The state of these pins is unknown. If these pins must be used, t hey require a pull - up or a pull - down configuration. The Arduino board allows the pins to be set in a pull - up configuration. If not it must be stablished an external pull - up or pull - down circuit in order to correctly work with these pins. 12. I/0 technical d etails Digital Output Waveform Digital Output Turn - off

Ardbox - Arduino I/Os 5V pins Th e Ardbox has some of the Mega board pins available. These pins can be programmed according to Arduino features such as I/Os operating at 5V or any additional features present in the pins (for example I2C communication in pins SCL and SDA). As this pins ar e directly connected to the Arduino Mega board they are not as well protect as the normal inputs. These pins are mainly meant to be used as prototyping. * IMPORTANT: Do not connect the terminals in the chart above to voltages higher than 5V. These terminals provide direct access to the Mega board. A part from the switch configuration there are some special conditions depending on these 5V. Now it is going to be shown the considerations to operate with these pins.

In order to implement this communication a 4.7k Ω pull - up resistor (IS.ACI2C - 4.7K ) is required. 9. Jum per Configuration General Jumper Configuration This jumper makes the choosing between connecting MAX232 to pins 0,1 of the Arduino Leonardo or with the MAX485. In order to use the RS - 232 Hardware Serial protocol both RS - 232 must be connected to the D1/D0. In order to use the RS - 485 Hardware Serial protocol both RS - 485 must be connected to the D1/D0. This jumper zone makes the choosing between connecting the inputs I0.2, I0.3 to pins 4 and 8 of the Arduino Leonardo respectively, or connect the RS - 232 ports to activate the Software Serial RS - 232. In order to use the inputs I0.2,I0.3 the jumper must be connected to the pins 4 and 8. So I0.2 must be connected wi th D4 and I0.3 must be connected to D8. *The jumpers that are not connected to the middle jumpers MUST NOT be Connected anywhere.

Additionally although the serigraphy only is expressed for the RS485 it is also the same for the RS232. So if it is desired to enable any of the Hardware Serial connection this is the function of these switches. See chapter 8 for more information 8.
