Appendix B CIP Information

Assembly Object Class

Code 0x0004

The Assembly Object binds attributes of multiple objects, which allows data to or

from eachobject to be sent or received over a single connection. Controllers that

do not have the ability to create and establish a class 1 (scheduled) connection

can utilize the Assembly Object in a Message Instruction to obtain both the input

and output assemblies of the RFID interface.

The following services will be implemented for the Assembly Object:

Different connection instances are needed for each RFID interface based on the

model. These class 3 connection instances are different than the class 1 instances

used by a ControlLogix or CompactLogix processor due to the limitations within

the SLC and Micrologix for handling Send and Receive data.

Use the table below to determine the class 3 connection instance and Send /

Receive size for your unit:
