Output (scheduled write) Data Table
The Output data table contains time-critical command and setpoint data that is
written to the CGCM-DLR unit by the ControlLogix controller.
The host controller automatically writes the data in this Controller Tag to the
unit at the scheduled update rate whenever a connection between the two exists.
This write occurs independently of the user program. The Output data table can
also be read and written by using unscheduled messaging. An unscheduled write
message is not accepted if there is a scheduled connection active.
Data Type
The Output data table is automatically created by using module-defined data
type AB:1407_CGCM:O:1.
Assembly Object Instance 1 - Output Data Table (scheduled write)
The Get Attributes Single service for instance 1 of the Assembly Object can
access the following information.
The Set Attributes Single service for instance 1 of the Assembly Object
(Class 0x04) can access the following information.
Configuration Checking
No range checks are performed on the Output data table.

TIP
Set Attribute Single is supported for this instance only when there is no
scheduled connection to it. Otherwise it returns a device state conflict error
0x0010.
