So we try to use UDP functions. There are only open, multicast open, write, read, close. We are sending data through UDP Write to device IP. First problem, we are not understanding how we need to built a sequnce in UDP protocol,how it must look like? We need to send 0 0 0 0 2 0 in one command, each number is 1 byte. Second we do not understend how to recive information from device, because UDP Read dose give Error 56/66. What should we do to force UDP Read to actualy read the device. We tried to open one port, then opened several, nothing seems to work, device stil answering to ping command in cmd but not in Labview. Is there any solutions?
