How can I avoid to poll the same value multiple times using a direct DLL call from the Applicom.dll that comes with the card? I'm only interested in updated data from the slave.
I sometimes miss some values during the polling, e.g a counter that is supposed to count 0,1,2,3,4,5,6,7... is being polled as 0,1,4,7...instead, even if I only poll one value.
Using WIN NT, PENTIUM III/933 Mhz and Labview 6i. The baudrate of the Profibus is set to 500 kbits/sec. The counter in the slave is being updated about every 70 to 100 ms/per increment.
Thanks to everyone.
