Commissioning Aids
During test mode or commissioning, the device information transmitted to a central control or storage device
can be influenced. There are tools available for testing the system interface (port F) and the binary inputs and
outputs of the device.

Prerequisites
In order to be able to use the commissioning aids described in the following, the device must be connected to
a control center via port F.
Description
Influencing Information to the Control Center During Test Mode
Some of the available protocols allow for identifying all messages and measured values transmitted to the
control center with "test mode" as the message cause while the device is tested on site. This identification
prevents the message from being incorrectly interpreted as resulting from an actual fault. Moreover, a trans-
mission block can be set during the test so that no messages are transferred to the control center.
This can be accomplished via binary inputs or using DIGSI via the USB interface.
The SIPROTEC 4 System Description states in detail how to activate and deactivate test mode and blocked data
transmission.
Testing the Connection to a Control Center
Via the DIGSI device control it can be tested whether messages are transmitted correctly.
A dialog box shows the texts of all indications which were allocated to the system interface (port F) in the
DIGSI matrix. In another column of the dialog box, you can define a value for the indications to be tested (e.g.
indication ON / indication OFF). After entering password no. 6 (for hardware test menus), the corresponding
indication is issued and can be read out in the event log of the SIPROTEC 4 device and in the substation control
center.
The procedure is described in detail in Chapter "Mounting and Commissioning".
Creating Oscillographic Recordings for Tests
During commissioning, energization sequences should be carried out to check the stability of the protection
also during closing operations. Oscillographic event recordings contain the maximum information on the
behavior of the protection.
