Hello,
I recently downloaded the euotherm labview driver from ni.com and I am using this USB to RS485 converter http://www.kksystems.com/english/html_files/product_pages/usb485.htm for communication, unfortunately I keep getting this error when using both example VI's.
1. When I use the process value monitoring example vi
Error -1073807339 occurred at VISA Read in Eurotherm 32xx Series.lvlib:Utility MODBUS RTU Receive Message.vi->Eurotherm 32xx Series.lvlib:Utility Read From Register - Floating Point.vi->Eurotherm 32xx Series.lvlib:Utility Read From Register - Float or Int.vi->Eurotherm 32xx Series.lvlib:Read Process Variables.vi->Eurotherm 32xx Series Process Value Monitoring.vi
2. When I use the temperature control monitoring example vi
Error -1073807339 occurred at VISA Read in Eurotherm 32xx Series.lvlib:Utility MODBUS RTU Receive Message.vi->Eurotherm 32xx Series.lvlib:Utility Read From Register - Integers.vi->Eurotherm 32xx Series.lvlib:Utility Read From Register - Float or Int.vi->Eurotherm 32xx Series.lvlib:Configure Instrument Mode.vi->Eurotherm 32xx Series Temperature Control Monitoring.vi
Can someone please help with this?
