Mitsubishi Electric has created a next-generation manufacturing technology that virtualizes
and simulates the motion of products and sensor data in FA controllers,
making the startup and replacement of assembly lines more efficient and
reducing on-site adjustment time up to 75 percent. It enables operators
to generate errors such as temporary line stops in a virtual
environment for the FA controller and then adjust actual line operations
accordingly.
Currently, assembly line validation is carried out manually according to
a test scenario, requiring repeated operational tests on an actual line
to generate uncommon and hard-to-replicate errors. Mitsubishi
Electric''s virtualization technology for FA controllers simulates
product signals and sensor data as if the actual line were running.
Because the design of the virtual line is flexible, the system enables
quick reproduction of errors. Also, since actual products are not
required to be on the line during the test, accidental damage and
preparation costs can be significantly reduced. The virtualization
technology reduces on-site adjustment time by 75 percent compared with
the current method.
Test programs previously used in computer simulations can be imported
for the virtualized testing. The technology can also be combined with
programs that replicate temporarily malfunctioning products or sensors
for automatic verification.
