3.7 Interface Types and HIMs
List of Interfaces with
associated HIMs
The table below provides a complete list of the currently supported interface
types and their associated HIMs. This list can be used to determine whether
development for a new HIM is required when support for a new protocol is be-
ing planed.
Note: DSB modules are used for protocols that have addressable devices.
DMB modules are used for protocols that have non-addressable devic-
es.
Note: When more than one module is available for an interface type, use the
hyperlink to look at the module properties for more information. Nor-
mally, the only difference is the number of connectors present on the
modules.
