Besides, when a process information input (SPI, DPI, STI, AMI, DMI, MFI, BSI and ITI) is reconnected
in monitoring direction, Test Mode updates the RTU500 database with the current real value of the
signal. The host systems receive this data update as well, and the Test Mode user interface displays
the signal's real value as well.

Regarding the visualization of the signals in the Test Mode user interface, the reconnected signals are
displayed with normal text again (no longer bold and/or green). The "Simulate" button and check-
boxes disappear for process information inputs, since it is not possible to simulate an input if the
signal is not disconnected from process.

Status indicator

The indicator in the upper left corner of the user interface displays the number of signals that are
currently disconnected from process, that is, the number of signals which are being simulated. The
indicator is independent of the signals that are currently displayed in the signals grid; it counts the
total number of signals disconnected from process.
If the number of simulated signals is zero, the indicator is black (Fig. 69).
