- Manufacturing Execution System
is a distributed system. It is essentially a quality assurance system
with tracking and genealogy which captures all the quality oriented data
generated during the different stages of manufacturing process, using
data acquisition systems and PLCs. The data generated at the machine integrated
terminals passes through Siemens L2 bus to the PLCs. The data which then
passes through Siemens H1 bus is captured and stored in a central server,
in a database. All the communications - inter process as well as through
the H1 bus are handled by TCP/IP sockets.
system also tracks the genealogy from the raw material to the finished
product and stores all the production and quality data as history. Two
dedicated servers are used for fault monitoring and also to generate breakdown
as well as preventive maintenance schedules.
