284 Motion Object Attributes
The fault bits are updated every coarse update period of the consuming Logix
processor. The fault bit attributes defined below can be handled by the Logix
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.
Control Sync Fault
The Control Sync Fault bit attribute is set when the Logix controller detects
that several position update messages in a row from the producing controller
have been missed due to a failure of the controller-to-controller
communications connection. This condition results in the automatic shutdown
of the associated servo module. The consuming Logix controller is designed to
“ride-through” a maximum of four missed position updates without issuing a
fault or adversely affecting motion in progress. Missing more than four
position updates in a row constitutes a problematic condition that warrants
shutdown of the servo module. The Control Sync Fault bit is cleared when the
connection is reestablished.
