10 Module Overview
Common Time base for Alarming System logs user interaction as well as alarm
events using common time reference.
The power industry requires sub 1 ms accuracy on first fault across
geographically dispersed architecture.
High Speed Applications
Packaging machines or sorters that have fast part cycles are often bottlenecked
by controller scan times. By switching to a time based solution, you can
remove many scan time critical components of the system. This programming
technique allows you to do predictive events and schedule outputs to run
things like diverters without having a scan time to match the part cycle time.
Motion Control
CIP Sync also provides a common time reference for distributed VFD drives,
servo’s, and controllers throughout the system. This allows controllers to
request axes reach a pre-defined position at a known time reference or run at a
set speed using the same reference. Since all drives and controllers in the
system have the same reference to time, the controller can issue simple
requests for axes to reach target positions in a synchronized fashion.
Global Position Registration
Registration refers to a function usually performed by the drive where a
physical input is triggered causing the drive to precisely capture the actual axis
position when the input event occurred. Rather than wiring inputs to the
registration input on all of the drives, this time based system lets you wire an
input to only one time based SOE input module. The time stamp returned for
that input, can be used by the motion planner to calculate the actual axis
position at the time the input triggered. This simplifies system installation,
reduces wiring costs, and provides a global machine registration for all the axes
in the system thru one SOE input.
