The of LOGO! Soft Comfort V6.1 is not available as a free download because it requires a paid license . While Siemens offers free upgrades and demo versions online, the initial full software must typically be purchased as a physical DVD (part number 6ED1058-0BA08-0YA1 ) or as an electronic software delivery (ESD) for companies.

Generally, no. Newer hardware requires newer software versions. V6.1 supports up to 0BA7. Using incompatible versions will fail to detect your device.

If you own a valid license for an earlier version (e.g., V5 or V6), you can often upgrade to V6.1 at a reduced cost through Siemens’ software update service. Check your existing license agreement.
