Hi all,

I have been implementing modbus communication in 1 of the apps using windows form, the source for the implementation was obtained from this website only. But the problem is the data processing is taking too much time for executing. So i wanted to know how to reduce the execution time & improve it performance. The minimum time it takes to process data is 500ms which is to slow i want to improve it.

The following link gives the entire code for implementing modbus protocol.
Simple Modbus Protocol in C# / .NET 2.0[^]

When viewed from the serial port sniffer or serial port monitor software to check the data, we can see that the process takes a min of 500ms to send a query & get the response from the slave.

So i want to know what exactly would be the problem...?

increase your baud rate ;-) and read this https://www.automation.siemens.com/WW/forum/guests/PostShow.aspx?PageIndex=1&PostID=207341&Language=en[^] maybe you have reached the limit of this very old protocol.
tune your communication - note: this is for modbus rtu:http://support.ge-ip.com/support/index?page=kbchannel&id=09237d4900112023bed2600fd0[^]
