Identification Systems Assembly applications frequently require identification of objects
used or manufactured. This is accomplished by systems that
read codes, optical characters, or radio frequency identification
(RFID) tags associated with these objects.
Siemens hand-held and stationary code readers provide
reliable, flexible reading, verification and optical character
recognition (OCR).
Siemens RFID systems utilize a different technology for sensing
objects. For these systems, a mobile data storage unit (tag) is
affixed to the object. Each tag stores information associated
with the object, or, when the object is a container, the tag may
store information about the items in the container. Data stored
in tags can be read from or changed by radio frequency (RF)
devices. Use of this technology simplifies the process of tracking
objects and streamlines the flow of material.

PLCs Because assembly processes vary in complexity, the types of
control systems and related devices employed also vary. In
addition to small- and medium-sized PLCs or other control
systems used to control individual machines, one or more
larger PLCs may be employed to collect data and coordinate the
operation of some or all of the system.
This overall coordination may include control of the full range
of motor control devices discussed thus far, from full-voltage
starters to precision drives. The specific PLC models used depend
on the size and complexity of the application.
Siemens SIMATIC PLCs are the foundation upon which our
Totally Integrated Automation (TIA) concept is based. Because
the needs of end users and machine builders vary widely,
SIMATIC PLCs are available as conventional modular controllers,
embedded automation products, or as PC-based controllers.
