All registers return zero or no response. What is wrong?

The FEMS Modbus TCP Read Access app must be active on the system. Without it, the FEMS box does not open port 502 and no registers are served. Confirm the app is installed and enabled in the FEMS App Center, then verify the Gateway can reach the FEMS IP address on port 502 from the same network segment.

Register addresses are shifted by one compared to the template. Why?

Some Modbus tools default to a base address of 1 instead of 0. The FEMS Modbus TCP interface uses zero-based addressing. Set the base address or address offset to 0 in your client configuration. The ModbusCloud Gateway already handles this correctly when using the template.

Why do write setpoints stop being applied after about 60 seconds?

The FEMS Modbus TCP Write Access app includes a built-in watchdog. A write setpoint is held for 60 seconds by default. If no new write arrives within that window, the system reverts to autonomous control. To maintain a continuous setpoint, send a fresh write command at least every 30 seconds. The timeout is configurable in the app settings.

Is it safe to write to set_active_power or set_work_state at any time?

Use write registers with care. Writing set_work_state can start or stop the inverter outside of normal operating sequences, which may trip protection mechanisms or affect warranty conditions. Always verify the current system_state and inverter_state before sending setpoints, and keep power setpoints within the bounds reported by original_allowed_charge_power and original_allowed_discharge_power.

The Fenecon Commercial40 is a commercial-scale battery energy storage system managed by the FEMS energy management platform, built on OpenEMS. This Modbus TCP template reads system state, control mode, inverter state, and grid mode, along with battery pack voltage, current, power, state of charge, state of health, and cycle count. It also reads three-phase grid and inverter voltages and currents, BMS DC-DC work state, individual cell voltages for up to 224 cells, and per-cell and per-string temperature extremes. Write registers allow active power, reactive power, and work-state setpoints. Connecting through a ModbusCloud Gateway gives you a full picture of this system across every site.
