Data Mapping Examples

Usage of the Control Word, Status Word and Live List affect how data is mapped to the network
interfaces in the Anybus X-gateway.
The following generic examples describe typical configurations. The actual representation of
data on the network is highly network-specific and is described in the Network Guide for the re-
spective interface.
Typical Slave-to-Slave Gateway Configuration
Fig. 3 Slave-to-slave example
This example illustrates how data is mapped in a typical slave-to-slave gateway configuration.
The Control Word and Status Word is here enabled for both networks.
Typical Master-to-Slave Gateway Configuration
Fig. 4 Master-to-slave example
This example illustrates how data is mapped in a typical master-to-slave gateway configuration.
The mapping is similar to the slave-to-slave configuration but also features the Live List, which
indicates the active status of the slaves that are attached to the master interface.
