established communications protocols have become the
de facto data super highways of today and the foreseeable
future. As a result, process control, equipment reliability,
and security are now of equal concern.
We Can’t Operate Without Reliable Power
All equipment connected to the Io T requires one thing:
a source of electrical power to function. However,
microprocessor-based electronics demand both a
high-level of power quality and reliable power source
primarily because they are constructed with high-speed
microcontrollers and volatile semiconductor memories.
The equipment’s application dictates the required level of
power quality and reliability.
As an example, a soft drink bottling company has a
minimum production run of 10,000 bottles of a given
brand. Its fully automated production line has been
designed and optimized to fill and process 10,000 bottles
without stopping. However, large motors used on the line
are causing voltage fluctuations elsewhere on the line that
adversely affect other microcontroller-based equipment.
In particular, the operation of the Programmable Logic
Controller (PLC) responsible for filling the bottles is
affected. As a result, hundreds of bottles are being
partially filled during every production run, requiring they
The offending PLC is connected to a companywide
Supervisory Control and Data Acquisition (SCADA)
network, which is responsible for controlling and
monitoring the entirely automated production line
process. The SCADA network is connected to the
company’s main business network to support automated
