Anybus X-gateway - 2.6 Data Mapping Examples

Description 10 (18)
2.6 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.
