Today's complex automation systems rely on
tightly-coordinated timeframes to meet desired outputs. For this reason, many
automation manufacturers have begun accepting the new clock synchronization standard
from the Institute of Electrical and Electronics Engineers (IEEE).
The Precision Clock Synchronization Protocol for Networked
Measurement and Control Systems (IEEE 1588) allows Ethernet network designers
to synchronize equipment from heterogeneous systems. This process can even be
done when device clocks have varying precision and resolution levels. The
protocol supports system-wide synchronization accuracy in up to a
sub-microsecond range, while requiring minimal network and local resources.
The specification was created by the IEEE in conjunction
with the National Institute of Standards and Technology, and can also be
applied to test and measurement applications, communication systems, and
electrical power applications.
Companies like Rockwell Automation and Intel have already
adopted IEEE 1588, while others continue to prefer alternative standards like
Serial Real-Time Communications Systems (SERCOS) and the Network Time Protocol.
Will you adopt IEEE 1588?
