  • NetCore下模拟和使用Modbus工业通信协议

    Tips:

      1、目前NetCore下与Modbus通信的框架主要选择了 Modbus.Net  https://github.com/parallelbgls/Modbus.Net

      2、modbus是常用的工业通信协议,在软件调试时可以通过modbus poll+slave模拟通信通过达到调试目的,下图是我使用软件

                1)为串口模拟工具

                2)为Modbus Slave模拟工具

                3)为Modbus Poll模拟,修改对应Value值即可发送到Slave

       

      调用和测试代码:

      

       public class ModbusTest
        {
            public Dictionary<string, ReturnUnit> GetModbusValues(List<AddressUnit> addresses, ModbusType connectType = ModbusType.Tcp, string connectString = "127.0.0.1")
            {
                var _modbusTcpMachine = new ModbusMachine(connectType, connectString, addresses, true, 2, 0);
    
                var result = _modbusTcpMachine.GetDatas(MachineGetDataType.Address);
    
                return result;
            }
    
            public bool SetModbusValues(List<AddressUnit> addresses, Dictionary<string, double> setDict, ModbusType connectType = ModbusType.Tcp, string connectString = "127.0.0.1")
            {
                var _modbusTcpMachine = new ModbusMachine(connectType, connectString, addresses, true, 2, 0);
    
                var result = _modbusTcpMachine.SetDatas(MachineSetDataType.Address, setDict);
    
                return result;
            }
    
            //获取测试
            [Obsolete("固定写死的测试方法,临时测试用")]
            public void TestGetModbusValues()
            {
                var addresses = new List<AddressUnit>();
                for (int i = 0; i < 6; i++)
                {
                    addresses.Add(new AddressUnit { Id = "1", Area = "4X", Address = i + 1, DataType = typeof(ushort) });
                }
    
                var _modbusTcpMachine = new ModbusMachine(ModbusType.RtuInTcp, "127.0.0.1", addresses, true, 2, 0);
    
                var result = _modbusTcpMachine.GetDatas(MachineGetDataType.Address);
    
                foreach (var item in result)
                {
                    Console.WriteLine($"Key:{item.Key} Value:{item.Value.PlcValue}");
                }
            }
    
            //设置测试
            [Obsolete("固定写死的测试方法,临时测试用")]
            public void TestSetModbusValues()
            {
                var addresses = new List<AddressUnit>();
                var setDict = new Dictionary<string, double>();
                for (int i = 0; i < 6; i++)
                {
                    addresses.Add(new AddressUnit { Id = "1", Area = "4X", Address = i + 1, DataType = typeof(ushort) });
                    var r = new Random();
                    var intValue = r.Next(0, 100);
                    System.Threading.Thread.Sleep(100);
                    setDict.Add($"4X {i + 1}.0", intValue);
                }
    
                var _modbusTcpMachine = new ModbusMachine(ModbusType.RtuInTcp, "127.0.0.1", addresses, true, 2, 0);
    
                _modbusTcpMachine.SetDatas(MachineSetDataType.Address, setDict);
            }
        }

       也可以使用Modbus-TCP Client Tester来模拟展现,可以写入或读写寄存器
