Modbus communication(stepping motor DRIVER LSD-CD) to commuicate with Rotary hallow system

[prady.siegen]

Hello All,

              I am using stepping motor driver as Modbus communication for the hallow rotary system from orientalmotor. Can anyone help with how to build VI for this and the clear picturisation view is attached below. 

Thank you

Hi prady,

- you need to install a MODBUS library for LabVIEW. There are several different implementations available with VIPM…

- you need to get a RS485 interface, the cheapest should be a USB-to-RS485 converter

Then read the manual coming with the motor driver to learn, which registers are needed/important. Set the values for those registers as described in the manual!

Thanks a lot for the info. but, i already have the above things that i mentioned and i am reading manual but, i cant exactly identify and sketch in the labview to get a rotational movement.

I definitely need some inputs and any example VI if possible
