Hi. I have some problems with connection between V570 and PC. I can't communicate via Ethernet with v570. But my program written in Java without any problems works with v280. Earlier, I worked without problem when I have Visilogic 126.96.36.199, but after programming Unitronics with Visilogic 8.6.1, my program stopped its properly work. My program connects to the PLC (opening socket), writing to socket, but when trying to read from it, there isn't any answer from PLC. The same problem was when I used another v570, 100% Ethernet card is working successfully. Can you help me?
