No, you can not use the TSXPCU1030 cable to connect to a TSX17. The CPU communication port connector is different. The TSXPCU1030 have a round mini-din connector at its end and the TSX17, if I remember..., have a DB15 female connector.
The TSXPCU1030 is used to program the PLC's Twido, Nano (TSX07), Micro (TSX37) and Premium (TSX57).
The commercial part number of the TSX17 cable is TSX17ACCPC.
