NI Modbus not sending command over RS 485

[kaustubh]

I am using Standard NI Modbus library for my application of communicating the modbus devices over RS 485.

I have build the simple vi with:

Ouside while loop

1. Ceate modbus

Inside while loop

2. Set active device

3. Read holding registers

4. Delay 1 sec

But, this is not sending query to modbus devices after every second.

Can anybody tell the reason or solution?
