Siemens has moved most older software versions behind Service & Support login or paid contracts. Free public direct downloads for V5.6 are rare. Your best sources are:
First, let us clarify the terminology. "Distributed Safety" is Siemens’ solution for programming safety-related functions (up to SIL 3 according to IEC 61508 and PL e according to ISO 13849-1) across a PROFIBUS or PROFINET network. Unlike standard logic, safety programs require redundant processing, diverse memory areas, and special "F-blocks" (Fail-safe blocks).
S7 Distributed Safety v5.6 specifically refers to the engineering software that integrates into the classic STEP 7 v5.x environment (not TIA Portal). This version is predominantly used for:
