### n8n Modbus Trigger Node

Source: https://github.com/lostedz/n8n-modbus/blob/master/README.md

This n8n community node allows workflows to be triggered by events from Modbus devices. It connects to Modbus TCP devices, monitors data changes, and can read/write holding registers. Installation requires following the n8n community nodes guide.

```TypeScript
/**
 * @description This node triggers workflows based on Modbus events.
 * @category Modbus
 * @param {string} host - The IP address of the Modbus device.
 * @param {number} port - The port number of the Modbus device (default: 502).
 */
async function modbusTrigger(this: any, { host, port = 502 }: { host: string; port?: number }) {
  // Implementation details for connecting to Modbus and triggering workflows
  // This is a placeholder and would involve actual Modbus client library usage.
  console.log(`Connecting to Modbus at ${host}:${port}`);
  // Example: const client = new ModbusClient(host, port);
  // Example: client.on('dataChange', (data) => this.emit('data', data));
}
