WindowsNT upgrade to Windows 2000 for Citect Communication with S5

Hi Folks,


When i upgrade the Citect V5.21 SPack G from Windows NT to Windows 2000 Professional , i have this message "Cannot find "siemen" driver..pop up during start the Citect. And the Citect will ask for shut Down..

The PLC is S5 135 and using Serial Communication..

Please help me on this

Regards

the message actually pop up " cannot find serial driver"

the inside the kernal windows is mention" cannot initialize comx " " cannot initialize driver "..

regards

The siemens driver needs to be installed on the computer running Citect. It does not get installed by default when Citect is installed. The driver can be downloaded from the Citect website. Regards Alan Case
