recommended for communication technology
for Industry 4.0.
Pharmaceutical and automotive parts
manufacturers are increasingly attaching
great importance to safe and secure
manufacturing. They started to use the
system to ensure that production data
has not been manipulated, proving that
products have been produced correctly.
Use Case 3: Standardized MES
Connection and Traceability
In one customer's production line,
many machines and devices of various
manufacturers were installed and the connection
method between the upper system
and the machines was not standardized.
The connection with the quality traceability
database was standardized with the database
direct connection feature. This system
has been deployed in each plant as the
global standard interface (see Figure 2).
There is also an application where
OPC UA is used in a machine. In the final
inspection of automotive parts, the
Omron NX701 machine automation controller
collects and analyzes the highspeed
analog signals of tens of kHz
required for judgment, stores all inspection
results in a traceability database
(SQL), displays the status and results
using SCADA, and controls the transfer
of the data. A direct connection to the
database is used to collect and analyze the
analog signals and store them in the database
and OPC UA is used to connect to
SCADA to display the status and results.
The controller is designed for equipment
and processes that require high
speed, high accuracy, and large-scale con -
trol such as high-speed filling machines
and packaging machines for drinks and
pharmaceuticals. Example processes in -
clude winding and laminating in the
manufacturing of automotive lithium-ion
batteries. In addition to high-speed/
high-accuracy control, such equipment
and processes also require MES and production
system connectivity and their
data must be stored in quality traceability
systems (Figure 3).
Use Case 4: Machine Interface
In order to remotely monitor an excavator
used in an underground mine, the
excavator and the SCADA in the monitoring
room are connected by OPC UA.
OPC UA is appreciated here because it
is easy to connect and can be used without
any complicated knowledge.

Then stop using complicated controllers for precision motion.
You shouldn't need a Ph.D. in control systems to program your
controller.
With Automation1, you
can now reduce your set
up time - in many cases,
from days down to minutes
- thanks to an intuitive
interface and machine
setup wizard. Automation1
is the most user-friendly
precision motion control
platform available.
In an application of operation monitoring
of metal machinery, OPC UA is
adopted to gather and visualize the
operation information of the machine
tool including a CNC. They are installed
in a large number of metal parts
processing lines, together with the in -
formation of the peripheral devices
controlled by a PLC and the information
of the operating environment
such as power and temperature. The
key point is that the information of
both the CNC and the PLC can be collected
and managed by one mechanism
(OPC UA).
