PLC because uses the modern large scale integrated circuit technology, used the strict
production craft manufacture, the internal circuit has adopted the advanced
from the diagnostic program, causes in the system also obtains the breakdown besides
the PLC electric circuit and the equipment from the diagnosis protection
suitable for the production-runs and so on, also may the cargo which produces carry
on transmits to the specific place.
The redundant reliability is the electricity control device essential performance.
enables us based on PLC and the monolithic integrated circuit difference even more
clearly to know PLC, is familiar with the PLC control system to the student the
