Using the ControlNet-to-FOUNDATION Fieldbus H1 Linking Device

Figure 4.5 Sample Cascaded AO Configuration

The linking device consumes analog values produced by the controller on
ControlNet and publishes these values on Fieldbus. The NI-FBUS
Configurator sets up the analog output devices to subscribe to their data on
Fieldbus. Each MAO block has its own schedule to consume data on
ControlNet and publish it on Fieldbus. For different rates of publishing on
Fieldbus, you must choose different MAO blocks as shown in Figure 4.6.

Figure 4.6 Sample Multiple Macrocycle AO Configuration

You do not have to connect to all the channels in an MAO block instance
before using another instance. You do not have to use the channels in order.
