AlarmIndication
The alarm conditions are displayed as alarm icons in the status display section and on
the operation screen such as the trend, digital, bar graph, overview displays. Detailed
information about the alarms is displayed in the alarm summary.
• AlarmLevelsandColors(Releasenumber3orlater)
You can set separate levels and colors for the four alarms on a single channel. When
multiple alarms occur, the DX gives higher priority to the display of alarms with higher
levels. It is easy to understand what processes are taking place when alarms occur if
you associate an alarm’s color with its level. Level and color settings are the same for
each channel.
