- Plug-in communication module: PLC and 4G module positions are marked on the module cover; the fitted bearer follows the order.
- Four time-of-use tariff registers, maximum demand, monthly and daily billing, two load profiles and timestamped event logs.
- Internal latching load switch, controlled by authorised commands and configured local conditions.
- Optical port and RS-485 interface for local reading, configuration and firmware transfer.
Meter functions
Measurement
- Active, reactive and apparent energy, import and export; combined active total; four-quadrant registers.
Instantaneous values
- Voltage, current, active / reactive / apparent power, power factor and frequency per phase.
Demand
- Block or sliding demand; base period 60 / 300 / 900 / 1 800 / 3 600 s; 1–15 subintervals; maximum demand overall and per tariff.
Tariffs
- 4 time-of-use registers; 12 intervals per day; 8 day profiles, 8 week profiles, 12 seasons, 100 holidays; stepped tariff up to 7 steps.
Billing and profiles
- Monthly billing (12 entries) and daily billing (62 entries); load profile 1 (demand) and load profile 2 (energy, 9 600 entries); up to 16 captured objects per load profile.
Load control
- Internal latching load switch; DLMS disconnect-control modes 0–6; load limits in 500 W steps; overcurrent reconnection sequence.
Events and alarms
- Standard, tamper, communication, disconnector and power-quality logs; three alarm registers with filters and descriptors; Data-Notification push.
Security
- Security policy 0–3; security suite 0: AES-GCM-128 authenticated encryption, AES-128 key wrapping; LLS / HLS associations.
Communication
- Plug-in module (PLC and 4G positions on the module cover); optical port (HDLC or IEC 62056-21 mode E); RS-485 (HDLC).
Display
- LCD with eight-digit data area, six-digit identifier and status symbols; automatic, manual and supply-off modes; up to 64 display objects.
Firmware
- Local (optical, RS-485) and remote image transfer with signature verification; metering continues during transfer.
