General Description M-DUINO FAMILY product
1.1 Zone - Nomenclature
The nomenclature shown in this point will be used in the whole User Guide, so it is
important to understand this nomenclature.
The nomenclature to differentiate the zones is based on the Alphabet, being A the
shield from below and D the shield from above. Having a B and a C in the middle of
them. It can have a minimum of 2 zones (A, B) and a maximum of 4 (A, B, C, D). The
nomenclature is represented on the picture below:
The inputs in the zone B are named I0.X, being X any number suitable in the
Shield. Outputs are named as Q0.X and relays as R0.X
The inputs in the zone C are named I1.X, being X any number suitable in the
Shield. Outputs are named as Q1.X and relays as R1.X
The inputs in the zone D are named I2.X, being X any number suitable in the
Shield. Outputs are named as Q2.X and relays as R2.X
1.2 Zone Distribution
A zone is completely common for every single M-Duino Family PLC. The rest of zones
can have two different shields. The two shields that can be in every Zone (except for A
Zone) are the Analog Shield or the Relay Shield. Only 1 Shield is allowed per Zone.
Depending on the combination that is made to build the PLC it can provide more
Analog Inputs/Outputs or Relays Outputs. All the zones (B, C, D) can be one of the two
Shields:
A ZONE
B ZONE C ZONE D ZONE D ZONE C ZONE B ZONE A ZONE
D ZONE
C ZONE
B ZONE

This is the list of our products depending on the combination of the shields. As it is
already said above the A Zone is totally common for all the M-Duino Family.
The nomenclature of the M-Duino Family products consists on placing the name of the
Shield/s after the total number of I/Os of the product.
For example M-Duino53ARR+ is a PLC with the 3 extra Zones (B, C, D), which are
Analog, Relay, Relay respectively. It has 53 I/Os.

they are all Analog they are not represented with this nomenclature. With the nomenclature represented in

Precautions
Read this manual before attempting to use the M-Duino PLC and follow its descriptions for
reference during operation.
3.1 Arduino Board
All M-Duino family PLCs include Arduino Mega Board as controller.
3.2 Intended Audience
This manual is intended for technicians, which must have knowledge on electrical systems.
3.3 General Precautions
The user must operate M-Duino according to the performance specifications described in this
manual.
Before using M-Duino under different conditions from what has been specified in this manual
or integrating M-Duino to nuclear control systems, railroad systems, aviation systems, vehicles,
combustion systems, medical equipment, amusement machines, safety equipment and other
systems, machines, and equipment that may have a serious influence on lives and property if
used improperly, consult your INDUSTRIAL SHIELDS representative. Ensure that the rating and
performance characteristics of M-Duino are sufficient for the systems, machines, and
equipment, and be sure to provide the systems, machines, and equipment double safety
mechanisms. This manual provides information for programming and operating the M-Duino.
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).

Ref. IS.MDUINO.XXX
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

Ref. IS.MDUINO.XXX
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.

Ref. IS.MDUINO.XXX
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/
How to connect PLC Arduino to PC
-Connect USB port from PLC to PC.
NOTE:
M-Duino Family uses USB-B cable.
-Open Arduino IDE interface:
-Select Industrial Shields boards -> M-Duino Family

Ref. IS.MDUINO.XXX
-Select the correct M-Duino Board.
-Select correct port.
How to connect PLC to power supply
-M-Duino Family PLCs are 12-24Vdc supplied. IMPORTANT: The polarity IS NOT
REVERSAL!
-Make sure that the live and GND connector of the power supply match the PLC.
-Make sure that the power supply mains output is not higher than 24Vdc.
