EasyModbus TCP slows down the windows application

[nayanavv]

Hi, I'm using EasyModbus TCP to connect to a slave device from a windows application (WinForms). I'm sending and receiving float values using the methods inside the timer for Modbus communication since the values should be communicated continuously.

modbusClient.WriteMultipleRegisters(register, ModbusClient.ConvertFloatToRegisters((float)variable, ModbusClient.RegisterOrder.HighLow)); (for writing to Slave)

and

ModbusClient.ConvertRegistersToFloat(modbusClient.ReadHoldingRegisters(register, 2), ModbusClient.RegisterOrder.HighLow); (for Reading from Slave)

It works well when the number of methods used inside the timer is less, but the application slows down when the number of methods increases.

Is there any way to speed up the whole communication?

Thanks Nayana

I don't have any problem with this and don't see any speed reduction.Can you please share your code or would you please explain how you call the methods and how often?

Hi Padanian,

I have resolved this issue by multithreading. The slow Modbus read and write applications were making the whole application not responsive(slow).
