Siemens Fieldbus Positioner

Dear Colleagues,

I need to upgrade the firmware of a Siemens Fieldbus positioner (SIPART PS2 FF). I want to know what hardware and software I need to do that.

Any hint or guide is welcomed.
About a year ago when I inquired about updating firmware for a HART PS2, I was told that buying a processor board was the only option. There was no publicly available firmware update software or firmware update file.

Given that you are referencing FF, a Siemens rep is most likely the best source of definitive information on such a topic. Policy could be different for a different model.
