Figure 8-10 Dry contact scheduling

slave SmartLogger instead of the master SmartLogger. Otherwise, SUN2000s that connect to
the master SmartLogger cannot execute the power grid scheduling command.

The slave SmartLogger and remote signal receiver Q are optional devices for connection.
If a slave SmartLogger is to be connected, you must add the slave SmartLogger over the WebUI of
the master SmartLogger.
The master SmartLogger connects to the slave SmartLogger over the Ethernet. The slave
SmartLogger functions as the network device for the master SmartLogger.
A slave SmartLogger transfers the commands sent by the master SmartLogger to devices connected
to the slave SmartLogger.
The remote signal receiver receives the scheduling commands sent by the power grid company,
converts them into dry contact signals, and then sends them to the master SmartLogger.
Remote signal receiver P receives the active power scheduling commands. Remote signal receiver Q
receives the reactive power scheduling commands.
