Hello, A few days ago I bought a second-hand packaging machine with Toshiba EX40H (2MCRB5) programmable controller. Now I need to re-programm this plc. I downloaded EXPDD2040 programming software, but I have no hardware key. Also I have no information about necessary cables or/and converters. Can anybody help me. I will be happy if I get anything about this plc. In advance thank you very much.
