Assembly Objects and Connections
There are 3 Assembly Object instances accessible from EtherNet/IP: input, output
and status. The input and output assemblies are linked to the input and output data
tables. The status assembly provides current status information about the Anybus-
X.
The assembly instances associated with these 3 assemblies are listed below.
Connection Points
Class 1 connections can be established to these assemblies using the connection
points listed in Table 6-2.
Connection sizes, when connecting to the input and output assemblies can be set
according to the size of the I/O data tables configured in the DeviceNet scanner
and the status and command words in the I/O assemblies. (see the assembly for-
mats below) If a connection is created with a size larger than that configured in the
DeviceNet scanner, the extra data will be filled with 0.
