Introduction
2.4 Master and slave modules
One of battery modules installed in the ESS acts as the master module, and the others
act as slave modules. As the representative of the ESS, the master module commu-
nicates with the higher-level system.
A module installed at the top or bottom of the rack must be the master module. Press-
ing the On/Off button on a module designates it as the master module and activates
not only the master module but also the slave modules.
All of the battery modules are sequentially assigned IDs by the master module.
If the top module’s On/Off button is pressed, the
module becomes the master module and also the
first module, as illustrated by this figure.
If the bottom module’s On/Off button is pressed,
the module becomes the master module and also
the first module, as illustrated by this figure.
NOTE
This manual assumes that the top module is used as the master module.
