electron+modbusRTU控制硬件，发现有时候读取超时，下发指令不成功，怎样能保证下发成功

Question

如题，如何能保证下发成功呢？读取也不超时。有时候还会出现 “CRC error”，最多的就是“Timed out”
下面是我的代码

const ModbusRTU = require("modbus-serial");
var rodClient = new ModbusRTU();
rodClient.connectRTUBuffered(“com1”, { baudRate: 9600, dataBits: 8, stopBits: 1, parity: "none" })
rodClient.setID(1)
rodClient.setTimeout(1000)

//循环读取设备信息
ipcMain.on("COM1", (event, args) => {
    if(roditem){
      clearInterval(roditem);
    }
    roditem = setInterval(() => {
      rodClient.readHoldingRegisters(com1Obj.readAddress, com1Obj.quantity).then(res => {
        event.reply('COM1msg', res.data)
      }, rej => {
        log.error("读取" + com1Obj.port + '：' + rej.message)
      }).then(blackBoxInstuctions).catch(err => {
        log.error('COM1ERR，黑盒' + err)
      })
    }, 100);
})

//写数据
 function closeOff(){
    rodClient.writeCoils(com1Obj.stopWriteAddress, com1Obj.stopValue).then(
      res => {
      },
      rej => {
        log.error("停止异常"+rej.message);
      }
    );
  }
