Teknic ClearCore无法连接Kinco GL070E HMI通信问题求助

问题现状 #

针对该通信对接问题已持续调试近3周，暂未找到可行落地方案，核心需求为通过任意可行方式将Teknic ClearCore控制器的运行数据输出至Kinco GL070E型号HMI。
调试阶段先后验证两类主流通信方案：

• RS232串口直连通信
• 以太网Modbus总线通信
  实测发现Tools40 Modbus库与ClearCore设备存在底层兼容性问题，全参数匹配情况下始终无法建立稳定正常的通信链路。
  调试过程参考了3份公开的开源项目文档、实操教程资料，按规则不提供外链跳转。

当前在用测试代码 #

因多日迭代调试未做代码整理，现有代码逻辑较为杂乱，当前烧录运行的测试代码如下：

#include "ClearCore.h"

// Defines the analog input to control commanded velocity
#define Estop ConnectorDI8 //Estop
#define counter ConnectorIO2 //induction3


// Select the baud rate to match the target device.
#define baudRate 9600




int count = 0;
int d = 1;
int x = 0;
int r = 0;

void setup() {
    // Put your setup code here, it will only run once:


    // Sets up serial communication and waits up to 5 seconds for a port to open.
    // Serial communication is not required for this example to run.
    
    Serial.begin(baudRate);
    uint32_t timeout = 5000;
    uint32_t startTime = millis();
    while (!Serial && millis() - startTime < timeout) 
      {
          continue;
      }

    
    
    //Configure Serial communication to HMI.
      // Configure COM-0 for RS-232 mode.
      ConnectorCOM0.Mode(Connector::RS232);
      // Set the data baud rate.
      ConnectorCOM0.Speed(9600);
      // (Optional) Set the data frame parity.
      ConnectorCOM0.Parity(SerialBase::PARITY_E);
      // (Optional) Set each data frame to use 2 stop bits.
      ConnectorCOM0.StopBits(2);
      // (Optional) Enable flow control.
      //ConnectorCOM0.FlowControl(true);
      // Open the serial port to enable data transmission.
      ConnectorCOM0.PortOpen();

}

void loop() {
/****Reset circuit***************************************************************************************************/
if (ConnectorIO1.State()==HIGH && r == 1)
  {
    digitalWrite(IO0, true);
    delay(300);
    r = 0;
    
  }

/****Estop circuit***************************************************************************************************/
while (ConnectorDI8.State()==LOW)
  {
    r = 1;
    digitalWrite(IO0, false);
  }


if (r==0)
  {
      Serial0.write(count);
      Serial.println(count);

  /****COUNTER*****************************************************************************************/
      
      if (ConnectorIO2.State() == HIGH)
        {
          count++;
        }

  }
}
