Object-name Description
01 (0×01)
The Identity Object is required on all devices and provides
general information about the device. It enables clear and
unambiguous identification of modules. Contains informa-
tion such as manufacturer name, product type, ident
number, revision number etc.
02 (0×02)
„Message
Router Object
(0×02)”
The Message Router Object provides a messaging connec-
tion point through which a Client may address a service to
any object class or instance residing in the physical device.
04 (0×04)
The Assembly Object binds attributes of multiple objects,
which allows data to or from each object to be sent or
received over a single connection. Assembly objects can be
used to bind input data or output data. The terms "input" and
"output" are defined from the network’s point of view. An
input will produce data on the network and an output will
consume data from the network.
06 (0×06)
„Connection
Manager
Object
(0×06)”
The Connection Manager Class allocates and manages the
internal resources associated with both I/O and Explicit
Messaging Connections. The specific instance generated by
the Connection Manager Class is referred to as a Connec-
tion Instance or a Connection Object.
