How can i connect LabView to a PLC or Profibus without using OPC?

[HIS]

I can access data from the PLC or through the Profibus using OPC. Unfortunately is this not fast enough since I need a faster sampling rate. Are there any faster ways to access the PLC data? I’m now using Siemens S7-300 and CP5613 with the driver S7-5613.

As I know, there is no other way connecting to Siemens PLC in LabVIEW except OPC so far. Maybe you can contact some Profibus interface vendors, they may have driver for LabVIEW.

Hello,

there is a company in Germany offering VISA drivers for Profibus communications (www.comsoft.de).
