Embedded
CIM PC in Fabrication
Project
Introduction:
Computer-integrated manufacturing (CIM) is
a method of manufacturing in which the entire production process
is controlled by computer. Typically, it relies on closed-loop
control processes, based on real-time input from sensors.
It is also known for providing flexible design and manufacturing
by allowing areas such as design, analysis, planning, inventory
control, and distribution to be linked through the computer
with factory floor functions providing direct control and
monitoring of all process operations.
System
Requirements: The
majority of current-gen production equipment includes CIM
functionality; in this application, the customer wanted to
design a CIM PC to integrate existing equipment that did not
have built-in CIM.
- Needed
to be compact in size since it's an add-on unit
- To
integrate both communication and digital I/O interfaces
- To
provide the production information that can be integrated
into an MES system
Project
Implementation:
UNO-2171:
Intel Pentium M/Celeron M Embedded Automation Computer
PCM-3641I:
4-Port RS-232 Module
PCM-3753I:
96-Channel Digital I/O PCI-104 Module

System
Description: The
PCM-3641I
is used to communicate with equipment's controller, to gather
the equipment operation, runtime and downtime information,
and then convert it into the MES server. On the other hand,
The MES server will download the production information into
the equipment through PCM-3641I's
serial communication port. Moreover, the PCM-3641I
is also connected with other additional devices (such as barcode
readers), to gather all the relative information. The PCM-3753I
is used to integrate with sensors, buttons and lights that
can record the critical operation information.
Conclusion:
This
new specific function controller reduced the overall dimensions
of the system by 50% (compared with the previous IPC chassis)
and saved 25% wiring time on integration and testing. It also
saved 37% on costs by adopting this controller into existing
equipment.
