Eaton C440/XTOE - Assembly Object and Instances

DeviceNet Configuration
18 C440/XTOE Electronic Overload Relay, DeviceNet MN04210002E—March 2011 www.eaton.com
Assembly Object, Class 0x04 (C440)
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. Various data sets can be
exchanged using I/O messaging. The data set to be
exchanged is determined by selecting an input and
an output assembly.
The adapter is designed with 2 I/O connections (poll and bit
strobe). These connections use the assemblies selected in
the vendor specific DeviceNet Interface object (0x94).
