I think connection.close() needs to be inside the connection. block. This worked for me:
modbus.tcp.connect(502, req.ip, { debug: "automaton-2454" }, (err, connection) => {
connection.writeSingleRegister({ address: req.register, value: Buffer.from([ 0x00, 0x01 ]) }, (err, res) => {
if (err) throw err;
console.log(res); // response
connection.close();
})
});
