Digitalpetri Modbus Save

High-performance, non-blocking, zero-buffer-copying Modbus for Java.

Quick Start

ModbusTcpMasterConfig config = new ModbusTcpMasterConfig.Builder("localhost").build();
ModbusTcpMaster master = new ModbusTcpMaster(config);

master.connect();

CompletableFuture<ReadHoldingRegistersResponse> future =
    master.sendRequest(new ReadHoldingRegistersRequest(0, 10), 0);

future.thenAccept(response -> {
    System.out.println("Response: " + ByteBufUtil.hexDump(response.getRegisters()));

    ReferenceCountUtil.release(response);
});
