Procedure for Operating on Logic Devices
To act on Logic Devices, follow the general procedure established above. The following belong
to this category of devices:
- State of
Automatisms
integrated in the equipment
-
Local / Remote Control
state of the position
- State of panel
Connected / Disconnected
As a consequence of the execution of this type of commands, the unit modifies the internal state
of the Logic Signals and generates the incidences of transmission of changes of state through
the protocol implemented (
PROCOME, DNP3, ...
). In this type of commands, what is
established for
ORDER FAILURE
will not apply since no applicable return signal exists.
9.4.5
Procedure for Managing Alarms
This procedure is only applicable when the alarms are managed at the UCP level, that is, when
the alarm panel is defined as with
Acknowledgement
in the design of the Configuration. On the
Alarm Screen, the boxes associated with each alarm can be empty, have blinking text or have
stable text, depending on the state of the signals that indicate the alarm.
To acknowledge an alarm, use the function key
F1
associated with the Alphanumeric Display.
Each time this key is pressed, the effect is extended to all the alarms. The evolution of states of
any one of the alarms is indicated in the flow chart of following figure.
