<div class="markdown_content"><p>Hello, i have a beginner's question. In the company have wago 758-870 plc where i need to make a backup program that is stored in it. So i trying to connect through network switch where is connect two wago plc's, my manual setting on the laptop is ip 192.168.0.128 and subnet mask 255.255.0.0. with WAGO Ethernet Settings i see plc's address is 192.168.0.50 (this is main plc i think) and second is 192.168.0.100 (plc for joystick) but program say for both not supported dont know why. Ok i run codesys v2.3 choose open program from plc pick target settings Wago 758-870-000-012 which writes on the plc sticker, now ask me for communication parameters i choose localhost via tcp/ip in address i write 192.168.0.50, port 1200, targetid is 0, motorola byteorder is yes, gateway option is connection tcp/ip, address is localhost and port is 1210. When i press ok open window and says loading program from plc, gateway server start light but after a minute i get an error communication error (#0) logout performed.<br/> So can anyone tell me where I'm wrong and how to solve it? Another question is what is needed to choose for complete backup just choose save codesys project? <br/> Sorry for the newbie question i need some directions for begin Thanks!!</p></div>
