Library for Modbus ???

[Minikisscool]

Hi, I have a project to control a motor system.
The communication is RS485 through Modbus via Serial.
The computer is the master and the control motor is the slave.
I have just one system to control

I found 3 free driver.

MODBUS Library for LabVIEW Version 1.21

LabVIEW Modbus API v1.1.3.32

MODBUS included in DSC module for LV2014
https://www.ni.com/docs/en-US/bundle/labview-datalogging-and-supervisory-control-module/page/lvmve/c...

I already made a development with 1.21 from NI.

Should it better to use Modbus library from DSC module ?
What do you suggest me ?

thanks in advance

Hi Minikisscool,

The Modbus Library for DSC is probably the more convenient to use but you need for that to have purchased the DSC module.

The option you have choosen (the free low level API) is probably the most commonly used and if you did not experience any particular troubles using it, I suggest you stick to it ; )

Have a nice day,

Hi Minikisscool,

As far as I know, DSC is not included in FDS, it's a separate module.

Strange, at work, we have a server licence.

anyway, I have no popup of 30 day try, so it mean that we have the licence.
it is a good news of me 🙂
