PCS7 programming software?

[dunc]

what software is required to program a PCS7 system?

this may be a really stupid question, but i cant seem to find a definitive answer from google searches etc. if i search for any PCS7 specific programming software, i cant see anywhere in which to purchase it from either?

TIA portal sounds very similar to how i understand the PCS7 system architecture is setup with 1 piece of software integrating everything between the PLC and HMI/SCADA. TIA portal lists all the hardware devices as used in the PCS7 system we have installed.

i am mostly used to Mitsubishi, so the Siemens stuff is a little alien to me, so i apologise in advance if there is an obvious answer i have overlooked!
