E10-npn, E10-Relay and all the H-series PLCs all use the WinTRiLOGI version 3.5 software (ladder logic only, no TBASIC). They cannot be programmed with i-TRiLOGI 6.xx.
We suggest you purchase the E10-npn Starter Kit at USD99.00 which include the PLC, the WinTRILOGI programming software and the DB9 cable.
