Hello azad_dsc The USB MPI/DP PC Adaptor needs 24V power from the device you plug it into (Pin 7 of the DB9 connector: +24V, Pin 2: 0V, see the manual for more). CPU DP and MPI ports as well as the DB9 test port on a repeater supply this 24V, remote I/O's station (e.g. ET200M, ET200Setc.) do NOT supply this 24V and the PC Adaptor won't work on them. Solutions: 1.) Buy an external power supply(6ES7 972-0CA00-0XA0). 2.) Buy a CP5711 I hope this helps |
