Output Types can also be assigned on this page. Each output can be configured
as:
Normally Open . . . . . . . . . . . . . . . . which means the relay is held open by the
controller, during periods of inactivity, and
then closed to indicate activity or provide a
signal.
Normally Closed . . . . . . . . . . . . . . . which means the relay is held closed by the
controller, during periods of inactivity, and
then opened to indicate activity or provide a
signal.
Configuring an Output to be Normally Open or Normally Closed is largely
determined by the state required, at the input receiving this signal, to start or stop
a device or process. Some Outputs are configured by the system based on
parameter settings made in the Hardware Parameters, as shown in the example of
Figure 3-11 .
If a Controller is attached to the PC then the Input and Output names from the
controller can be read and displayed in the Input/Output Names page of the Editor.
If all parameters were queried from the Main Page then the names will be shown
on the Input/Output Names page when the page is opened. Any name assigned by
the system will be shown with a grey background and will be protected against
editing (see
Figure 3-15 ). Otherwise, when the page is opened the names can be
read from the controller by pressing the Query All button on the Input/Output
