282 Motion Object Attributes
Axis Status Bit Attributes
Servo Action Status
The Servo Action Status bit attribute is set when the associated axis is under
servo control. If the bit is not set then servo action is disabled.
Drive Enable Status
The Drive Enable Status bit attribute is set when the Drive Enable output of
the associated physical axis is currently enabled. If the bit is not set then
physical servo axis Drive Enable output is currently disabled.
Shutdown Status
The Shutdown Status bit attribute is set when the associated axis is currently in
the Shutdown state. As soon as the axis is transitioned from the Shutdown
state to another state, the Shutdown Status bit is cleared.
Configuration Update in Process
The Configuration Update Status Bits attribute provides a method for
monitoring the progress of one or more specific module configuration
attribute updates initiated by either a Set Attribute List service or an SSV in the
user program. As soon as such an update is initiated, the ControlLogix
processor sets the “Configuration Update in Process” bit. The bit will remain
set until the Set Attribute List reply comes back from the servo module
indicating that the data update process was successful. Thus the Configuration
Update Status Bits attribute provides a method of waiting until the servo
configuration data update to the connected motion module is complete before
starting a dependent operation.
