TECHNICAL NOTE
MOTION APPLICATION ENGINEERING GROUP
Example: CPU X Scan
Network Y Scan = 1 msec (8 axes of servo)
Final performance note for all layers in a system:
The data being transferred to the network devices is based on the 'motion and I/O registers." All
registers are updated at the end of the Program Layer scan at the same time, and the interface
between each layer synchronizes to bring about system determinism. Hence, the performance is
predictable. Network delay can be fed forward at a certain resolution to reduce steady state error
of high-speed applications. This is key point for maximum performance!
