Device-specific Functionality

Apart from the general basic functionality, the Web Monitor contains the synchronization function for the

7SJ62/64. The following information can therefore be displayed via the Web Monitor.

The synchronisation function includes the following views:

• Synchronization range

The synchronisation ranges are displayed in a coordinate system. The X axis shows the frequency and the

Y axis the voltage.

• Synchronoscope

The synchronoscope is dynamically visualized by three diagrams showing respectively the difference angle,

the difference voltages and the difference frequency.

• Synchronous systems

Synchronous networks are visualized by a pie chart and the current measured values.
