8.3 Viewing and Clearing Events
The module maintains an event queue that reports the history of its
actions. You can view the event queue using an LCD OIM or
VS Utilities software.
To View and Clear Events Using an LCD OIM
Use the procedure shown in figure 8.2 to access the event queue
using the LCD OIM. Note that you must have the RECOMM-PBUS
module as the selected device to access the event queue.
Events
Many events in the event queue occur under normal operation. If
you encounter unexpected communications problems, the events
may help you or Reliance Electric personnel troubleshoot the
problem. Table 8.5 lists events that may appear in the event queue.
