refer to the computer that executes this software, connecting to a

comm err
Comm Err is a possible state of the Firing attribute of a transition.
When the transition is in the Comm Err state, a communications error
with phase logic has been detected while the transition was in the
Stopping/Resetting/Pending states of the firing process. The
transition has rolled back to the beginning of the
Stopping/Resetting/Pending process and is awaiting good
communications and a RESTART command before re-initiating the
firing process.
committed
Committed is a possible state of the Firing attribute of a transition.
When the transition is in the Committed state, it has committed to the
firing process, but is not in the process of firing because either the
transition is in the HELD state or the parent procedure is in MANUAL
mode.

resources are identified as either exclusive-use resources or shared-use
resources.
