This read-only object reports the specific type of event that triggered an alert table entry, following the PrtAlertCodeTC textual convention, with defined codes such as cover opened, interlock opened, jammed, or configuration changed. An admin uses this as the primary field for automated alert classification, routing jam codes differently from configuration-change notices, for example. For example, a row reporting ePjammed(8) alongside a prtAlertGroup of input and a group index of 2 tells the admin exactly what happened and roughly where.
