Woodward easYgen-3000XT
Genset and CHP controller with generator and mains measurement, engine values, status and alarms.
The Woodward easYgen-3000XT is a genset controller that runs, protects and synchronises engine-generator sets and gas-engine CHPs, for example in greenhouses, in island and mains parallel operation. This Modbus RTU template reads generator and mains power, voltages, currents, energy, engine values, status and alarms, and lets you write start and stop commands and the power, frequency and voltage setpoints from ModbusCloud.

Send your device list
If a device is not in the library yet, we build the template for free as soon as we have the register data.
Use cases
- Show generator power, voltages, currents and frequency of a greenhouse CHP on a dashboard next to the mains power at the grid connection.
- Get an email when an alarm word is not 0, for example a generator, mains or engine alarm that is latched and not yet acknowledged.
- Track active energy and operating hours in the history and plan maintenance with the hours and days until the next service.
- Adjust the active power setpoint remotely, or let an automation write it when the energy price changes.
- Watch coolant temperature, oil pressure and exhaust gas temperatures from the engine ECU and alert on a threshold.
Installation
Connect the RS-485 port of the ModbusCloud Gateway to terminals 5 (Y) and 6 (Z) of the controller, with 120 ohm termination at both ends of the bus.
On the controller set parameter 3173 to Halfduplex, check 19200 baud, no parity, 1 stop bit and slave ID 1, and leave parameter 3184 on 5010.
In ModbusCloud add a Modbus device (RTU) with the slave ID of the controller and import this template.
Check that Protocol ID reads 5010 and that generator frequency and battery voltage show plausible values.
Delete the registers you do not need, such as J1939 values when no engine ECU is connected, so each reading cycle stays short.
Things to watch for
The controller does not answer on RS-485. What should I check?
The controller is set to full duplex by default. For a 2-wire bus set parameter 3173 to Halfduplex and use terminals 5 (Y) and 6 (Z), not 1 and 2. Then check 19200 baud, no parity, 1 stop bit and slave ID 1 (parameter 3188; 0 switches Modbus off), swap the two wires, and fit 120 ohm at both bus ends.
All values look shifted by one register. Why?
Read Protocol ID first. With the right offset it shows 5010. If you find 5010 one register further, the device was added with a 1-based address; this template uses the bus address. If it shows 5016, the controller sends data telegram 5016: use that template, or set parameter 3184 to 5010 and restart the controller.
Why do the scaled power and voltage values not match the display?
The 16-bit values marked Scaled use the exponents in Power, Voltage and Current Scaling Exponent: the real value is the reading times 10 to that power. With the default power exponent 3 the power reads in kW. The 32-bit registers such as Total Generator Power and Generator Voltage L1-L2 have a fixed scaling and need no correction.
Writing a start command or a setpoint has no effect. What is wrong?
Start, stop and acknowledge react to a rising edge: write 0 first, then the command, and keep bits 2 and 3 at 0. Interface setpoints only work if the AnalogManager uses the interface value as source, for example 05.56 for active power. The controller forgets these values at power down. Writing from ModbusCloud is off by default per gateway and is switched on at your request.
Why do the J1939 engine values show no useful data?
These values come from an engine ECU over CAN J1939. Without such an ECU, or for values your ECU does not send, there is no measurement. Delete those registers. Display versions of the controller can take up to 2 seconds to answer, 3 with J1939, so fewer registers keep the reading cycle short.
