This manual provides information for programming and operating the GPRS/GSM Controller.
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.
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 Industrial 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 go to: “File -> Preferences” located in the top left corner.
2.
In Additional Boards Manager URLs write the following: http://apps.industrialshields.com/main/arduino/boards/package_industrialshields_index.json
3.
Press OK to save the changes.
4.
Go to: Tools -> Board: … -> Boards Manager
5.
Search for “industrialshields” on the browser.
6.
Click install (selecting the latest version).
Following these steps you will be able to see now the Industrial Shields Boards:
Once it is selected the Ardbox Family or M-Duino family an extra option will appear on Tools:
There, it can be selected the exact model for every family.
In this case, the GPRS/GSM Controller uses the MDuino19R+ model, as you can see in the following image:
Also there are some examples of programming in File -> Examples -> M-Duino Family.
Furthermore there are some extra libraries that can be found in Industrial Shields github. https://github.com/IndustrialShields/

If it is desired to use an Analog Output the pin must be set to OFF and the pin that will provide this analog output is represented with A0.X, being X any number of the tables above.
GPRS/GPS I/Os 5V pins
The GPRS/GSM Controller 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 are 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.
The Arduino board available pins are summarized in the table below. In order to access some of these pins the configuration switch must be set to OFF position (see section 8) and some extra considerations must be taken in consideration when using these pins.

*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.
I2C pins – SDA/SCL
The I2C protocol is meant to work in a pull-up configuration. A pull-up configuration means that when the pin is at rest (nothing connected to it) it always reads a HIGH value. In this case it reads 5V when nothing is connected. The pull-up configuration is stablished by default in these pins.
If it is meant to work them as a GPIO at 5V, it has to be considered that they are pull-up inputs.
*IMPORTANT: I2.5 & I2.6 are not pull-up inputs although they are referred to the I2C pins
(switch configuration). There is a “reverse pull-up circuit “that is stablished in order to have the same behaviour as the other inputs.
Serial 0 – RX0/TX0
The Serial0 protocol can work also as a 5V pin. These pins should be used ultimately, only in case that all the 5V pins are already performing a function. This is because they are shared with the USB interface. If using these pins, the USB communication cannot be working at the same time. When the PLC is not installed, the USB communication is normally required for debugging, uploading and intercommunicating with the Ethernet controller. If using both interfaces at the same time the Arduino board will get blocked.
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 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.
Serial 1 – RX1/TX1
In the GPRS/GSM Controller, Serial 1 is used to communicate through the Sim800L integrated
GPRS/GSM Module. If you want to use Serial 1 instead of GPRS/GSM, you must set the Pin 2
(Pin used as the GPRS/GSM) always at high position.
Remember: if you use the Serial1 in your program, you will not be able to use the GPRS / GSM functionalities!
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 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.
SPI – MISO/MOSI/SCK
These pins can only work as a 5V pins if the Ethernet protocol is not going to be used. As the
Ethernet protocol uses the SPI to communicate with the Arduino board, both behaviours cannot happen at the same time as the Ethernet would not work.
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 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.
Pin 3
This pin is only referred to the inputs I0.1. If the switch configuration is in OFF position the pin
Pin 3 will be available.
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 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.
Pin 2
REMEMBER THAT PIN2 IS USED BY THE SIM800L MODULE AS RESET PIN, SO IS NOT
AVAILABLE IN THE GPRS/GSM CONTROLLER!
IF YOU WANT TO USE SERIAL1, YOU MUST SET THE PIN2 ALWAYS AT HIGH POSITION.
A Zone Features: Communications & RTC & uSD
RS-232
The Arduino Mega function code to access the RS-232 port in the M-Duino is Serial2 (pins 16 and 17 of the Arduino Mega).
For the RS-232 communication protocol there isn’t any switch that affects it. So it does not matter the configuration of the switches to implement a RS-232 communication.
Using the boards of Industrial Shields, there is a library that simplifies the RS-232 implementation.
RS-485
For RS485 communication protocol the defined Arduino Mega pins are showed in the chart below.

For the RS-485 communication protocol there is only one switch that affects in this communication. The RS-485 protocol will be always enabled, the only switch that affects is the one called “FD rs-485 HD” (See Section 8). This switch makes the choosing between RS-485
Half Duplex or RS-485 Full Duplex (RS-422).
Using the boards of Industrial Shields, there is a library that simplifies the RS-485 implementation.
I2C
I2C communication DOES NOT REQUIRE a pull-up resistor for the M-Duino Family. The pull-up resistor is already implemented in the PCB.
I2C communication is configured by switches, so the switches must be configured in order to enable the I2C communication.

Industrial Shields does not provide any library to implement the I2C as it can be used the standard library of Arduino called Wire.
SPI
The M-Duino pins used for the SPI bus are summarized in the table below. For SPI bus MISO,

TTL
M-Duino has two TTL ports, RX0/TX0, RX1/TX1. TTL0 is accessed with the function Serial (pins 0 and 1 of the Arduino Mega). TTL1 is accessed with the function Serial1 (pins 18 and 19 of the
Arduino Mega).
In order to use the TTL pins the configuration of the switches have to be the following one:

If the switches RX1/I1.6(I1.1) & TX1/I1.5(I1.0) are in OFF mode, the RX1/TX1 will be enabled. In order to use TTL3 these switches must be in OFF mode.
Ethernet
M-Duino Ethernet port controller is based on w5500 IC, which is the compatible IC compatible with Arduino Ethernet2 Shield libraries. All Ethernet shield Arduino libraries are compatible with the M-Duino. In the M-Duino, W5500 IC communicates to the Mega board via SPI bus (SS
Arduino Mega pin 10).
RTC
M-Duino RTC Module is based on the DS1307 Chip. This chip works with the I2C protocol communication, so it is required to have enabled the I2C protocol.
4 switches have to be configured in order to enable the RTC features:

I2C must be enabled in order to communicate with the RTC. See section 11 I2C to enable it.
Using the boards of Industrial Shields, there is a library that simplifies the RTC implementation called RTC.
uSD
The micro SD uses the SPI communication to interact with the Arduino Mega. The SPI protocol is always enabled, as there are no switches that configure it. However, there is a switch that must be placed to ON mode in order to communicate with the uSD:
D53(SD): If this Switch is OFF, it enables the Chip Select of the microSD socket and disables
Q2.0. If this switch is ON, it enables the Q2.0 output. If the switch is in ON mode the microSD can’t be used.
The uSD socket is found in the TOP part of the communication Shields, so in the frontal part of the PLC, it is required to open the plastic found in the frontal part and the socket is located under the supply of the Arduino.

Using the boards of Industrial Shields, there is a library that simplifies the uSD implementation called SD. It is the same as the Arduino library, with the only modification of using the pin 53 to select the Chip Select of the uSD chip.
GPRS/GSM
The SIM800L module is the integrated module for the use of GPRS / GSM in this PLC and to program it you must download this library on your Arduino IDE.
You can test the GPRS / GSM functionality using the examples that come with the library:
When defining the pins in the program, take into account that the internal connections between the Sim800l module and the Arduino Mega are the following:
Arduino Mega Pinout
5Vdc
GND
Tx1 (Pin 18)
Rx1 (Pin19)
Pin 2
Sim800L Pinout
Vcc
GND
TxD
RxD
RST
How to define it in a sketch:
#define FONA_RX 19 //RX1 on Arduino Mega
#define FONA_TX 18 //TX1 on Arduino Mega
#define FONA_RST 2
The GPRS/GSM protocol is always enabled as there are no switches that configure it. the GPRS / GSM protocol uses the Serial1 of the equipment to be able to communicate and the pin2 for the module reset.
If you want to use Serial1, you must indicate in the program that pin2 is always in High position. In case of using the Serial1, the GPRS / GSM communication can not be used.
