2.4 Data Mapping
If enabled, the Control- and Status Words, and the Live List (when available), affects how data is
mapped to the on-board network interfaces.
Note:
The actual representation of the data on the network is highly network specific and is described
in detail in the interface addendums for your product.
Typical Slave to Slave Gateway Configuration
The figure below illustrates how data is mapped in a typical slave-to-slave gateway configuration. Note
the Control- and Status Words, which in this particular example has been enabled for both networks.

Typical Master to Slave Gateway Configuration
The figure below illustrates how data is mapped in a typical master-to-slave gateway configuration. The
mapping is similar to that of the slave-to-slave configuration above, but additionally also features the
‘Live List’, which indicates the active status of the slaves attached to the on-board master interface.
