Assembly Object
(Class ID 04
H
)
The Ultra5000 with DeviceNet uses Assembly Objects to send generic
data to and from a Master (scanner) device over an I/O connection.
The terms Input and Output are defined from the scanner's point of
view:
• Output Assemblies are defined as the information that is output by
the scanner and consumed by the Ultra5000.
• Input Assemblies are consumed by the scanner or are the scanner's
input.
The Ultra5000 with DeviceNet allows you to choose between various
Input and Output Assemblies, thereby choosing the data format of the
messages that are passed back and forth between the Ultra5000 with
DeviceNet and the scanner over the I/O connection. The following
parameters select the Assembly Object instances that are exchanged
over an I/O messaging connection.
