Both
Writing Inputs and Simple Orders , once they have been decoded, must be tagged
(connected) so they can be dealt with by the Logic. This is performed by means of another
software process called
Input Connection Process . This association of signals as well as the
decoding of the PROCOME / DNP3 code depends on the Configuration loaded in the unit. Once
these signals have been tagged, the Logic will determine what they are used for.
7.2.2.b Inputs from the Protection Subsystem
The signals that get to the Control Subsystem from Protection are: the Input Signals from
Protection, the Alternating Current Measurements made by Protection and the Reclose
Counter ( 7IRD-A/J Models).

States of the Protection Subsystem
The Input Signals from Protection ( EP ) that are used by Control vary from Configuration to
Configuration and can be both Protection Auxiliary Contact Outputs or Trip Outputs and
Protection
LEDs . These signals can be sent to the exterior through Communications after going
through Output Tagging ; they can be presented directly in the Display, pass on to the Alarm
Panel and be used by the Logic after tagging them.

Alternating Current Measurements
The Alternating Current Measurements ( V, I, P, Q,... depending on the model and its
Configuration) are sent directly through Communications to the Central Unit. The
measurements are viewed in the Graphic Display on the corresponding screen (see Chapter 9).
The Logic also associates these measurements with their own tags to be able to treat them one
way or another depending on the Configuration. Generally these signals are used to activate
Alarms or Outputs when a threshold setting has been exceeded. If there is a measuring board
in the unit, these measurements sent from Protection will not appear. Instead, the measuring
board will capture and send the measurements to Control.

Reclose Counter (7IRD-A/J Models)
The Reclose Counter does not go through the Logic; instead it is viewed directly through the
Graphic Display.
7.2.2.c Physical Inputs
All the Physical Inputs can be sent through Communications, encoding them in Output
Tagging , or used by the Logic, adapting them beforehand through the Input Connection
Process . Without going through the Logic, these signals are viewed directly in the Graphic
Display. Physical Inputs can be of two types:

Inputs from Contact Transducers . These are the ones called EF in Figure 7.1. These
signals, in addition to what is explained in the preceding paragraph, can go to the Alarm
Panel and/or to the Single-wire objects.

Inputs from Measurement Transducers . The signals called SC are those that get to the
Control Subsystem from the measurement transducers.
