Commissioning Aids
In test mode or during commissioning, the device information transmitted to a central or storage device can be
influenced. There are tools available for testing the system interface (port B) and the binary inputs and outputs
of the device.
Applications
• Test Mode
• Commissioning
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 B.
2.20.9.1 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 pre-
vents the message from being incorrectly interpreted as resulting from an actual fault. Moreover, a transmission
block can be set during the test so that no messages are transferred to the control center.
This can be implemented via binary inputs, using the interface on the device front and a PC.
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 display texts of all messages which were allocated to the system interface (port B) in
the DIGSI matrix. In another column of the dialog box, a value for the messages to be tested can be defined
(e.g. message ON / message OFF). After having entered password no. 6 (for hardware test menus), the cor-
responding message is issued and can be read out in the event log of the SIPROTEC 4 device and in the sub-
station control center.
The procedure is described in detail in Chapter "Mounting and Commissioning".
Checking the Binary Inputs and Outputs
The binary inputs, outputs, and LEDs of a SIPROTEC 4 device can be individually and precisely controlled in
DIGSI. This feature can be used, for example, to verify control wiring from the device to substation equipment
(operational checks), during start-up.
A dialog box shows all binary inputs and outputs as well as LEDs of the device with their present status. The
operating equipment, commands, or messages that are configured (masked) to the hardware components are
also displayed. After having entered password no. 6 (for hardware test menus), it is possible to switch to the
opposite status in another column of the dialog box. Thus, you can energize every single output relay to check
the wiring between protected device and the system without having to create the alarm allocated to it.
The procedure is described in detail in Chapter "Mounting and Commissioning".
