Field C" will show a C if the task has been designated as CRITICAL
in the configuration for the rack. CRITICAL tasks are those that
cannot be stopped individually, i.e., all tasks must be stopped in
order for the task in question to be stopped.
An M in field M" indicates that the task has been modified, but has
not been saved from the Processor module. This field is used only
when tuneables have been changed either by the operator, or for
UDC tasks, by the PMI operating system, or when Ladder Logic tasks
have been modified. For more information about saving tasks from
the Processor module, see section 14.4.
Field A" will show a U" if the user has task access, or O" if another
user has task access to the task. For single user (nonĆnetwork)
applications, this field will be blank or will display U" if the user has
edited the task.
Finally, Status" shows whether each task loaded in the rack is
currently running (RUN) or stopped (STOP), and whether there has
been an error (ERROR) in each task.
