Performance

Overview

Creating a remote I/O system, requires the use of network components and designs that support switched Ethernet communication, including:

full duplex transmissions
100 Mbps transmission speed
QoS prioritization of RIO packets

This chapter introduces you to devices that meet these performance considerations. It also presents system typical system recovery times, and describes methods to help improve system performance.

What Is in This Chapter?

This chapter contains the following topics:

System Selection Considerations
140 NOE 771 •1 Performance
System Throughput Considerations
Calculating the Minimum MAST Cycle Time

determinism

For a defined application and architecture, the ability to predict that the delay between an event (change of an input value) and the corresponding change of an output state is a finite time t, smaller than the time required for your process to run correctly.
