示例： ~~~aardio import wsock.tcp.modbusClient; //创建 Modbus TCP 客户端 var client = wsock.tcp.modbusClient("127.0.0.1", 502, 1); //连接服务器（可选指定超时秒数） var ok, err = client.connect(3); if(!ok){ print("连接失败:", err); return; } print("已连接到 Modbus TCP 服务器"); //读取保持寄存器 var registers, err = client.readHoldingRegisters(0, 10); if(registers){ print("保持寄存器值:"); for(i=1;#registers){ print(" 地址", i-1, "=", registers[i]); } } else { print("读取失败:", err); } //写入单个寄存器 var ok, err = client.writeSingleRegister(0, 1234); print("写入寄存器:", ok ? "成功" : err); //读取线圈状态 var coils, err = client.readCoils(0, 8); if(coils){ print("线圈状态:"); for(i=1;#coils){ print(" 线圈", i-1, "=", coils[i]); } } //写入多个寄存器 var ok, err = client.writeMultipleRegisters(10, [100, 200, 300]); print("写入多个寄存器:", ok ? "成功" : err); //关闭连接 client.close(); ~~~
