Output (scheduled write) Data Table
The Output data table contains time-critical command and setpoint data written
to the CGCM unit by the ControlLogix controller.
Data in this Controller Tag is automatically written by the host controller to the
unit at the scheduled update rate whenever a connection between the two exists.
This 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:0 (Revision 2.
x) or
AB:1407_CGCM:O:1 (Revision. 3. x).
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 can access
the following information.
Configuration Checking
No range checking is performed on the Output data table.
Table 8 - Get Attributes Single (service code 0x0E)
Name Attribute ID Data Type Value
Data 3 UINT See Output (scheduled write)
Data Table, Assembly Instance
1
Size 4 UINT 56
Table 9 - Set Attributes Single (service code 0x10)
Name Attribute ID Data Type Value
Data 3 UINT See Output (scheduled
write) Data Table,
Assembly Instance 1
TIP
Set Attribute Single is supported for this instance only when there is no
scheduled connection to it. Otherwise it returns the error
CI_GRC_BAD_OBJ_MODE.
