Error conecction with Fx3U-Enet-ADP protocol UDP frame 1E #13

When trying to connect to the fx3ge, fx3u or fx3u-enet-adp plc via udp protocol, the gx work 2 software requires a destination port, consequently the communication node shows timeout, reading the library I was able to solve it in the following way in the mcprotocol file: add into function MCProtocol.prototype.connectNow under in the line self.netClient = dgram.createSocket("udp4"); (Line359) the next code if (cParam.frame == "1E") { self.netClient.bind(cParam.port); }
