2.5.14 Alarm List
In industrial auto-control applications, alarming is a very important function. It can be used in
many cases. Alarm list is the most direct and simple method.
Every project of OP10 can have a cluster of alarm list information. Every piece of
information corresponds to a relay. The addresses of all the relays are continuous. The user can
designate the initial address of the relays. When any of the relays jumps from OFF to ON, the
corresponding alarm information is activated. OP10 will pop up the alarm window, where the
alarm information is displayed in the first row. If another relay jumps to ON, the new information
will be displayed in the second row. When some alarm relay jumps to OFF, the corresponding
alarm information will disappear automatically.
To log the alarm information, press to pop up the alarm list dialog box:

description” column and enter the information “Temp. too high”. Press “Enter” to show the screen
as the following figure:
