4.15.1. Event Log Monitor
To access this dialog:
In the Project Pane, double-click Event Log.
The Event Log Monitor is one of your most important troubleshooting tools. The Event Log
Monitor displays all events that have occurred in the controller, such as issued commands,
changed parameters and errors. The Event Log Monitor is an important aid in troubleshooting.
It can be used to:
• Determine whether a command was successfully issued. The entire command, with
parameters, is displayed.
• Find out which, if any, error occurred.
• Determine where a command was issued from, for example, from a PLC, from a User
Program, from the Command Tool.
Each entry in the Event Log Monitor has the following components:
Component Description
# The number is solely for indicating the order of the events.
Time The time the event occurred is given in the following format: dayd
hour:minute:second:millisecond
The time is measured from when the RMC was last powered up, and is not
a precise time. For troubleshooting, this same time can be displayed in
plots and is useful in matching events with the plot data. In the Plot
Manager, on the View menu, choose Show Absolute Time. The Plot
Detail window will include the absolute time of the cursor in the currently
displayed plot.
Event Describes the type of event.
Details Provides additional details on the event, such as the previous and changed
values, command source, etc
The Event Log itself is in the RMC. The Event Log Monitor simply displays the RMC's Event Log.
On the RMC75E and RMC150E, the Event Log will hold up to 8192 entries. When the maximum
number of entries is reached, the oldest entries will disappear.
On the RMC75P and RMC75S, the Event Log is limited to the lesser of 512 entries or 2048
total words. When the maximum number of entries is reached, the oldest entries will
disappear. Notice that if the Event Log Monitor is open and online with the RMC, it will store up
to 8192 entries, even though the RMC75P and RMC75S store less.
Clearing the Event Log
To clear the Event Log, click the Clear Event Log button on the toolbar in the Event
Log window. This will remove all the entries from the Event Log.
