CHAPTER 8 – Alarms OMRON
Page 126 Release 2.0
This dialog always shows the log listed in date and time order.
The widths of the alarm fields can be widened or narrowed as required using the
mouse to drag the column boundaries.
The Print Contents of Alarm Log View toolbar button causes the messages in the Alarm
History dialog to be printed. Before printing, ensure that the printer has been set up
correctly. The alarm log itself is simply a text file (projectname.UAL) that may be examined
or printed using any of the usual utilities available under Windows, such as Microsoft
Notepad. When the alarm log becomes full it is copied to the alarm backup
(projectname.UAB) and a new alarm log file created. This switch over system uses a quick
‘append’ function for every alarm and prevents intensive write operations.
