ABSTRACT
With the development of modem industrial production, pneumatic
technology,hydraulic technology, sensor technology, PLC network and communications
technology, technology integration and the formation of the close hydraulic, aircraft
electrical, mechanical and electrical integration, automatic control technology optical
applications in industry production is playing an increasingly important role in
automated production systems have become an important component of industrial
production. Point. Germany FESTO company developed MPS(Modular Production
System)modular production system for industrial an automation on a production system
is based on the electrical machine(liquid) integration technology, PLC control combined
with automatic robot can complete the processing and assembling of the cylinder
systems.
The subject in this paper si to MPS pneumatic automatic production line detection
unit as an example, the detection unit of the modular control system. Two main areas of
work carried out, one of the detection unit hardware circuit design, and second, to
design its control system. To SIEMENS S7-200 PLC as the core control system,
complete detection unit and decomposition process of each module to complete the
detailed design,program design, coordination between the modules reasonably designed
to transmit information, complete the online work of each module detailed design
process.
Key words:PLC; detection unit; production lines; pneumatic
