Recommended Posts

hi, guys anyone please give labview mb slave vi.. i need to communicate with PLC master .......

hello,

You can get it from NI website here : http://sine.ni.com/d...a/epd/p/id/4756

I recommend you read the page carefully, specially this part :

Please note that this is an example program and not an official NI Product. For a more complete, fully supported MODBUS solution, NI recommends the LabVIEW Datalogging and Supervisory Control Module.

I prefer using the IO Servers for connecting to Modbus (although have successfully used the above API in the past).

NI Serial 3.7 (should be out now or real soon) now allows connection to e.g. RS-485 C-series module through the Scan Engine - which is great!
