Axis Fault Bit Attributes
All of the fault bit attributes defined below can be handled by the
ControlLogix processor as a Major Fault by configuring the associated Group
Object’s “General Fault Type Mechanism” attribute accordingly. Otherwise
any specific fault handling must be done as part of the user program.
Physical Axis Fault
If the Physical Axis Fault bit is set, it indicates that one or more fault
conditions have been reported by the physical axis. The specific fault
conditions can then be determined by accessing the fault attributes of the
associated physical axis.
Module Fault
The Module Fault bit attribute is set when a serious fault has occurred on the
motion module associated with the selected axis. A module fault affects all
axes associated with the motion module. It generally results in the shutdown of
all associated axes. Reconfiguration of the motion module is required to
recover from a module fault condition.
Configuration Fault
The Configuration Fault bit is set when an update operation targeting an axis
configuration attribute of an associated motion module has failed. Specific
information concerning the Configuration Fault may be found in the Attribute
Error Code and Attribute Error ID attributes associated with the motion
module.
Module Fault Bit Attribute
The Module Fault Bit attribute is a collection of faults that have module scope
as opposed to axis scope. Besides being a valid attribute for axes of data type
Servo and Servo Drive, this attribute is also valid for a consumed axis data
type. In this case, however, the module is the producing Logix processor rather
than a motion module such as the 1784-PM02AE or 1784-PM16SE.
