4.4.1 Logic interface
(a) Logic interface for AS/NZS 4777.2:2020, also known as inverter demand
response modes (DRMs).
The inverter will detect and initiate a response to all supported demand response
commands within 2 s. The inverter will continue to respond while the mode
remains asserted.

NOTE: Supported DRM command: DRM0, DRM5, DRM6, DRM7, DRM8.
(b) Logic interface for VDE-AR-N 4105:2018-11, is in order to control and/or
limit the inverter’s output power.
The inverter can be connected to a RRCR (Radio Ripple Control Receiver) in
order to dynamically limit the output power of all the inverters in the
installation.
