To learn about the Network Delay subsystem behavior and for instructions on building

and integrating the subsystem, see:

• “How the Network Delay Subsystem Works” on page 2-36

How the Network Delay Subsystem Works

The Network Delay subsystem models a communication link that samples information

from the ABS controller and conveys that information to the braking system. The

following sections discuss how the network delay subsystem works, before providing

instructions to build the subsystem and integrate it with the existing ABS system to

complete the hybrid model.

Network Delay Subsystem Contents

• A control signal from the ABS Controller block enters the subsystem via the In1 block.

The Timed to Event Signal gateway block converts the time-based signal from the

controller into an event-based signal, so that the data is available to the discrete-

event blocks. In any SimEvents model, the way that the software converts time-based

signals to event-based signals depends on the solver you use for your simulation.

In this tutorial, the model uses a variable-step solver. For more information, see

“Variable-Step Solvers for Discrete-Event Systems”.
