7.3.4 Testing the System Port
Preliminary re-
marks
If the device has a system port and uses this for communicating with a control center,
you can test with the DIGSI device operation whether indications are correctly trans-
mitted. You must avoid to use this test possibility during live operation.
The port test is made in the DIGSI mode Online:
 Double-click the directory Online. The operating functions for this device will ap-
pear.
 Click Test. In the right pane of the picture the available functions appear.
 Double-click in the list Generate Indications. The dialog box Generate Indica-
tions is opened (see Figure 7-8, page 273).
Structure of the
dialog box
In the column Indication the display texts of all indications are displayed which were
allocated to the system port in the matrix. In the column Setpoint status you deter-
mine a value for the indications that shall be tested. Depending on each indication type
for this several input boxes are offered (e.g. ON / OFF). By clicking on one of the but-
tons you can select the desired value from the pull-down menu.

Danger!
The sending or receiving of annunciations via the system port by means of the test
function is a real information exchange between SIPROTEC and the control center.
This information would execute the corresponding functions (e.g. follow-up com-
mands) in the control center.
