7.2.3 Test Messages to the System (SCADA) Interface during Test Operation
Depending on the type of protocol, all messages and measured values transferred to
the central control system can be identified with an added message “test operation”-
bit while the device is being tested onsite (test mode). This identification prevents the
messages from being incorrectly interpreted as resulting from an actual power system
disturbance or event. As another option, all messages and measured values normally
transferred via the SCADA interface can be blocked during the testing (block data
transmission).
A password for test and diagnostics is required (password no. 4) to block the
messages and measured values.
Data transmission block can be accomplished by controlling binary inputs, by using
the operating panel on the device, or via DIGSI
®
4.
If binary inputs are used, then the appropriate inputs must be configured.
