LabVIEW with Siemens hardware communication

[NELCO]

My application has Siemens AC Drive with Siemens PC CP5613 card being provided. Communication with the drive is thru' Profibus with LabVIEW. Does LabVIEW have a direct interface to communicate with Siemens CPS5613 card.

Hi!

No, unfortunately direct communication between LabVIEW and this card is impossible. (Theoretically you can looking for examples, which delivered with this card and calling DLLs for accessing, r/w Dual-Port RAM and so on, directly from LabVIEW, or over DLL-wrapper, but this not very easy). So, better way - using OPC server, which normally delivered with this card. Over OPC you can get access to Profibus. You can use OPC.SimaticNET server, or OPC.SimaticNET.DP (inline) server. Better way - using over LabVIEW DSC, but you can also to get acces over DataSocket without DSC (if you have not more than 30 items for reading and writing)

With best regards...
