Hello.

T400 with this order number is T400 without any program, for its programming you need Step7, CFC and D7-SYS software to write your own program.

To be sure ask the previous owner what program T400 have.

There may be 3 cases.

1. T400 with order number6DD1606-0AD0 (which you mentioned) is empty T400. It may be programmed usingStep7, CFC and D7-SYS. To work with this T400 you must have this program on your PC and the same software (Step7, CFC and D7-SYS), so you should ask the previuos owner about this program. Uploading the program is not possible.

2.T400 with order number 6DD1842-0AA1 or 6DD1842-0AA0 is the same T400 with preloaded standard program SPW420 (axial winder). To work with this T400 you should use DriveMonitor. This T400 have parameters like in the drive, you may upload parameter values or change parameters.Uploading the program is not possible.

3. Earlier there was available for ordering SPW420 on CD with order number 6DD1843-0AA0. This is the source code of SPW420, which could be opened/edited usingStep7, CFC and D7-SYS and downloaded to the empty T400 (6DD1606-0AD0). After that it is possible to work with T400 as usingStep7, CFC and D7-SYS, as using DriveMonitor.Uploading the program is not possible.
