Unscheduled Write Data Table
The Unscheduled Write data table contains gains and other configuration
parameters, that can be written to the CGCM unit by the ControlLogix
controller regardless of the excitation state.
Data in this Controller Tag is written by the host controller to the unit by using
unscheduled messaging controlled by the user program.
Data Type
The Unscheduled Write data table is automatically created by using the
appropriate module-defined data type depending on the CGCM unit firmware
revision.
Assembly Object Instance 6 - Unscheduled Write Data Table
The Get Attributes Single service for instance 6 of the Assembly Object can
access the following information.
The Set Attributes Single service for instance 6 of the Assembly Object can access
the following information.
Configuration Checking
When an unscheduled write is received, the CGCM unit verifies that individual
parameters are within the range indicated in the table below (for example,
perform range checking). If an out-of-range parameter is detected, the CGCM
unit ignores all data in the unscheduled write in the message instruction. The
CGCM unit does not perform application checking (is a value suitable for the
particular application) or dependency checking (is a value reasonable based on
other values entered).
