Status
Three status LEDs are provided
indicating the following states:
The first LED indicates the status of the GPIO.
For Inputs the logical status and for Outputs
the status of the relay.
▪ For outputs, the logical status is "1" ( )
when the relay is closed.
▪ For edge triggered inputs, the internal
Object/AmpPreset states are the same as
the GPIO status and vice versa.
▪ For level triggered inputs, the GPIO status
is defined by the external voltage
applied.

The second LED indicates the status of the
related Object (binary object) or AmpPreset.
Objects/AmpPresets and GPIOs are
evaluated separately.
▪ For Objects, the logical status is "1" ( )
when the Object is logical "1" (binary
object).
▪ For AmpPresets, the logical status is "1"
( ) when the AmpPreset is loaded and
not modified.
The third LED illuminates as soon as an error
has occurred ( ).
Provided the corresponding GPIO is
selected, a corresponding message will be
issued on the bottom left of the GPIO screen.
