What instruments?

What type of instruments?

What does the manual for the instrument say about reading the serial no.

How are you communicating with them? Are they GPIB instruments? Are they DAQ instruments?

What do you mean by "2 parameter display" and "3 parameter display"?

Data logging of temperature and humidity and pressure through modbus protocol

Developing universal data logger with help of labview

That tells us absolutely nothing. You have to look at the manuals for the instruments and see if they provide a means to get that information. We are not mind readers. We do not know what instruments you are using. If you cannot understand the manuals, then post a link to where they can be found and perhaps someone may be willing to tell you the command.

I am not familiar with modbus.

But, I think that is dependent on the manufacture of your temperature, humidity and pressure devices

What does the manual from the manufacture of your devices say?

Is there a command that your devices will reply to?

[Nagaa]

yes it sends reply also . ok sir i will find out clearly by looking into manual .
