Assembly Object Properties
The CIP Assembly Object (Class 0x04) provides assembly instances, attributes
and services that facilitate data transfer between the CGCM unit and the
ControlLogix controller. Specific assembly object properties are listed with each
data table below.
Input Data Table (scheduled read)
The Input data table contains time-critical status data read from the CGCM unit
by the ControlLogix controller.
Data in this Controller Tag is automatically read by the host controller from the
unit at the scheduled update rate whenever a connection between the two exists.
This occurs independently of the user program. The Input data table can also be
read by using unscheduled messaging.
Data Type
The Input data table is automatically created by using module-defined data type
AB:1407_CGCM:I:0.
Assembly Object Instance 2 - Input Data Table (Scheduled Read)
The Get Attributes Single service for instance 1 of the Assembly Object can
access the following information.
