[Climber81]

Goodmornig,

I'm Mauro Pialorsi, an elctronical engineer from Italy. I'm working with Labview 8.5 to comunicate with the PLC Siemens S7-300, using the Applicom card 1500s7. When I read/write values from the internal DB of the Applicom card, using Shared Variables, occur an error, named -1950679035. What's the problem of this error?
