When playing the example from the README, I get the following error: "binary.Write failed: binary.Write: invalid type int" and "ISO : Invalid Buffer passed to Send/Receive'19'" about gos7 HOT 7 OPEN

I use PLC S7-300, 400, 1200, 1500, gos7 runs good. I guess you should use real hardware device. @warleyjr10
