DEAR ALL,
I habe a problem with connecting wincc 6.0 and tp177a. i need to upload the back from T177A , make some changes and download it back. i configured TP177A configuration:
adress=1
channel,-mpi.
baud 187.5kbps.
plc, s7 300, 313c.
adress=2
my pg/pc interface set to MPI .with same baud
i am able to connect to plc but not HMI.
MY PC ADAPTER USB MODEL:6ES7972-0CB20-0XA0.
.
do i have to use prosave or wincc flexble?.
should i connect to HMI alone. i tried this also.
please help.!

Regards,

dear friends, badly in need of help.

wincc flexible. But uploadability is not guaranteed.

so its not possible with wincc 6.0?

No WinCC v6.0 cannot be used with a Simatic Panel such as TP177A. The software for Simatic Panels is called WinCC Flexible, or WinCC v11.
Apart from that, an upload of the full program from a Simatic Panel requires some steps to be done by the original programmer, steps that are almost never done.
And, the upload of the full program is not possible with a TP177A panel at all ! This feature is only supported by bigger panels.

Even if the project is upload it can not be edited or opened,It can only be downloaded in same type of HMI.
