Assembly Object Properties
The CIP Assembly Object (Class 0x04) provides Assembly Instances, attributes
and services that facilitate data transfer between the CGCM-DLR unit and the
ControlLogix controller. Specific Assembly Object properties are listed with each
data table.
Input Data Table (scheduled read)
The Input data table contains time-critical status data that is read from the
CGCM-DLR unit by the ControlLogix controller.
The host controller automatically reads the data in this Controller Tag from the
unit at the scheduled update rate whenever a connection between the two exists.
This read 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 2 of the Assembly Object
(Class 0x04) can access the following information.
Configuration Checking
No range checks are performed on the Input data table.
