Errors and Omissions
The information in this document has been carefully checked and is believed to be
accurate; however, no responsibility is assumed for clerical, typographical, or
proofreading errors, or omissions.
Residual Risks
The control and drive components of an Industrial Shields PLC are approved for
industrial and commercial use in industrial line supplies. Their use in public line
supplies requires a different configuration and/or additional measures. These
components may only be operated in closed housings or in higher-level control
cabinets with protective covers that are closed, and when all of the protective devices
are used. These components may only be handled by qualified and trained technical
personnel who are knowledgeable and observe all of the safety information and
instructions on the components and in the associated technical user documentation.
When carrying out a risk assessment of a machine in accordance with the EU
Machinery Directive, the machine manufacturer must consider the following residual
risks associated with the control and drive components of a PDS.
1. Unintentional movements of driven machine components during commissioning,
operation, maintenance, and repairs caused by, for example: − Hardware defects
and/or software errors in the sensors, controllers, actuators, and connection technology
−Response times of the controller and drive − Operating and/or ambient conditions not
within the scope of the specification − Condensation / conductive contamination −
Parameterization, programming, cabling, and installation errors − Use of radio devices /
cellular phones in the immediate vicinity of the controller − External influences /
damage.
2. Exceptional temperatures as well as emissions of noise, particles, or gas caused by,
for example: − Component malfunctions − Software errors − Operating and/or
ambient conditions not within the scope of the specification − External
influences / damage.
3. Hazardous shock voltages caused by, for example: − Component malfunctions −
Influence of electrostatic charging − Induction of voltages in moving motors − Operating
and/or ambient conditions not within the scope of the specification − Condensation /
conductive contamination − External influences / damage
4. Electrical, magnetic and electromagnetic fields generated in operation that can pose
a risk to people with a pacemaker, implants or metal replacement joints, etc. if they are
too close.
5. Release of environmental pollutants or emissions because of improper operation of
the system and/or failure to dispose of components safely and correctly.

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 Industrial Shields boards, these are the steps that must be followed.
Requirements:
Arduino IDE 1.8.0 or above (better to always have the latest version).
Steps:
1. Open Arduino IDE and go to: “File -> Preferences”located in the top left corner.
2. In Additional Boards URLs write the following:
http://apps.industrialshields.com/main/arduino/boards/package_industrialshields_index.json
If you already have an URL inserted, input an “,”between both URLs.
3. Press OK to save the changes.

6. How to connect PLC to power supply
-10 I/Os 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.
-Suggested power suppliers
The standard, Part 1 of IEC 61010, sets the general safety requirements for the following types
of electrical devices and their accessories, regardless of where use of the device is intended.
The equipment must be powered from an external power source in accordance with IEC
61010-1, whose output is MBTS and is limited in power according to section 9.4 of IEC 61010-
1.
WARINING: Once the equipment is installed inside an electrical cabinet, the MTBS cables of
the equipment must be separated from the dangerous voltage cables.
Compact DIN rail power supply. Assembled on 35mm
DIN Rail:
-12Vdc / 24Vdc
-2.5A
-30W
Industrial Shields power supplies provide parallel
operation, overvoltage protection, and overcurrent
protection. There is a LED inductor for power status,
the power supply is certified according to UL.
