Monitoring jacks
4.6.4
A monitoring jack including a LED is provided so that the user can monitor a binary signal on
the logic straightforwardly. For example, when the user wishes to monitor the operating state
of a relay function, set the signal number (Data ID) that the user wishes to monitor; then the
user can see lighting the LED when the relay is operated. Using with an oscilloscope, the user
can also observe the binary signal that comes from the monitoring jack; three monitoring jacks
(Term A, B, and C) are available on the front panel.

When the user wishes to test the phase-A element the OC1 relay using an oscilloscope,
for example, set the phase-A monitoring point (44001 8000011C20†) for the setting [Term A],
as shown in Figure 4.6-5. Consequently, the OC1 operating signal is outputted to the jack at
the Term A. The LED at the Term A is also lit in step with the output signal. The user can use
to monitor the phase-B and phase-C signals using by settings respective Data IDs for the [Term
B] and [Term C]. We shall see the menus for the Term A to Term C in Chapter
Setting sub-menu: Signal monitoring screen.
