I<->O IND1 and I<->O IND2
The object indication function blocks I<->O IND1 and I<->O IND2 indicate the
open, close and undefined states of a disconnector or an earthing switch.
7.2.3.
I<->O POS
The function block for logic control position selector, I<->O POS, makes it possible
to choose remote or local position via the input Remote, which facilitates the flexible
selection of control position. The Remote input can be found in
Main
menu\Configuration\Input Signals\Remote
.
In remote position, the circuit breaker can only be controlled via remote
communication and, accordingly, the local position only enables operation via the
HMI and the digital inputs.

7.2.4.
I<->O IND3
The object indication function block I<->O IND3 indicates the state of the motor
(running/stopped) in H07.
7.2.5.

The alarm indicating functions ALARM1-8 are used for controlling alarm LEDs.
The configuration-specific signals to which the alarm indicating functions can be
connected are the following:
