Overview
Figure 1-8
precise time synchronization.
As shown in the example on the top of the figure, IEEE Std. 1588 allows precision control over a
distributed Ethernet network. Precise timing delivery allows drive units to be placed where required.
Traditional mechanical control mechanisms can limit the placement of systems.
In the bottom of the figure, timing synchronization at the drive enables flexibility in system configuration.
Issues due to mismatched cable lengths are minimized. Servos can be added or deleted without having to
rewire other servos. Industrial control applications typically augment IEEE Std. 1588 hardware to provide
trigger inputs and outputs
In summary, IEEE Std. 1588 support in the MPC8313E enables accurate synchronization of clocks with
varying precision, resolution, and oscillator stability in distributed systems. IEEE Std. 1588 synchronizes
individual clocks to maintain accurate distribution-wide timing. It enhances applications that need local
clocks at each control node and provides sub-microsecond synchronization over long distances using
standard cabling. Target applications for systems with IEEE Std. 1588 are test and measurement
appliances and industrial control and automation.
