Demand Response Mode (DRM)
MINI ES that cooperates with DRED controller could receive the demand signal from
the Grid to connect or disconnect with the Grid and limit power of charging or
discharging.

The MINIES supports the DRM0 mode and is used in conjunction with the DRM0
combination switch.DRM0 can be configured through a third-party debugging tool. The
below debugging tool Modbus Slave is used as an example
MINIES disables DRM0 mode by default. If you need to switch it on, you can use the
third-party debugging tool to set the register of DRM0 address. The default address is
128.After turning on DRM0 mode, the combination switch (as shown below) is
connected to the rear panel of ESS through standard RJ45 network cable, The "DRM"
interface is ready to use.
The MINIES supports the DRM function as specified in AS4777.2.2015.The terminal
block inside the MINIES is used for connecting to a demand response enabling device
(DRED).
The DRED asserts DRMs, The MINIES detects and initiates a response to all
supported demand response commands within 2s.The following table lists the DRMs
