Hello Dear All, in our project we have to control yokogawa wt3000 using LabView Software. We have used driver from the yokogawa site for the device and it works well via GPIB connection, but not via LAN. We called the support from Yokogawa and National Instruments and found out, that we have to use the tmctl.dll library (see 2 pdf-files in attachment). I've tried (not sure, about that. It is correctly ?): Tools -> Import -> DLL there I've choosed the tmctl.dll and tmctl.h files and LabView has created a lvlib with several VI's (Tmc ****.vi and x TMC ****.vi) I've got a couple of questions. How have I to change the source-code where I use "normal" (yokogawa driver for GBIP) VI's (do I have to do it ?). Can I use the driver from yokogawa or have I to write a new one? What else have I to do? If you need more information, let me know. Thank you very much ! Best regards: Alexander The files we've got: tmctl.lib tmctl.h tmval.bas tmctl.bas TmctlAPINet.dll ykusb.dll YKMUSB.dll USBTMCAPI.dll tmctl.dll and TMCTL library user's manual with describtion for using with Microsoft Visual C++

Solved!

Hi,

In the ZIP an older driver. This contains the VI's you mentioned.
