8.3.7
Test Mode and Blocking Data Transmission
If the SIPROTEC
®
4 device is connected to a central or main computer system via the
SCADA interface, then the information that is transmitted can be influenced.
If
7HVWPRGH
is set
21
, then a message sent by the device to the main system has
an additional test bit. This bit allows the message to be recognized as resulting from
testing and not an actual fault or power system event.
If
'DWD6WRS
is set
21
, transmission to the SCADA is blocked.
Both of these features should be checked. The procedures for setting
7HVWPRGH
and
'DWD6WRS
are described in Sub-section 7.2.3. Note that when DIGSI
®
4 is being
used, the program must be in the
2QOLQH
operating mode for the test features to be
used.
8.3.8
Checking the Binary Inputs and Outputs
Preliminary Notes
The binary inputs, outputs, and LEDs of a SIPROTEC
®
4 device can be individually
and precisely controlled in DIGSI
®
4. This feature can be used, for example, to verify
control wiring from the device to substation equipment (operational checks), during
start-up. The test feature should not be used for routine maintenance when the device
and protected equipment are in service (“hot” conditions).
Note:
After the Hardware Test is complete, the device enters a start-up phase. All
message buffers are erased.
The Hardware Test can be done using DIGSI
®
4 in the online operating mode:
q
Open the
2QOLQH
directory by double-clicking; the operating functions for the de-
vice appear.
q
Click on
7HVW
; the function selection appears in the right half of the window.
q
Double-click in the list view on
+DUGZDUH7HVW
. The dialog box of the same name
opens (see Figure 8-16).
Hardware Test
Dialog Box
The dialog box is horizontally divided into three groups:
%,
for binary inputs,
5(/
for
output relays, and
/('
for light-emitting diodes. Each of these groups is associated
with an appropriately marked switching area. By clicking in an area, components with-
in the associated group can be turned on or off.
In the
6WDWXV
column, the present conditions of the hardware components are sym-
bolically shown. The present physical conditions of the binary inputs and output relays
are shown as symbols for open and closed contacts. The present condition of a light-
emitting diode is shown as the symbol for an LED, turned on or off.
DANGER!
Changing the status of a binary input or output using the test feature of DIGSI
®
4
results in an actual and immediate, corresponding change in the SIPROTEC
®
device. Connected equipment such as circuit breakers will be operated by these
actions!
