For LOGO! 9, customers need LOGO! Soft Comfort V9.0 or later. It is the engineering software for creating, testing, simulating, documenting and transferring LOGO! programs from a PC to the LOGO! device.

LOGO! Soft Comfort V9 supports LOGO! 9 Basic Modules, LOGO! TDE and the new LOGO! 9 device types. It can be used on Windows, macOS and Linux, giving customers flexibility in their engineering environment.

With LOGO! Soft Comfort V9, customers can create new applications, adapt existing projects and prepare programs before transferring them to LOGO! 9.

Yes. Existing LOGO! circuit programs from previous LOGO! generations can be reused with LOGO! 9 using LOGO! Soft Comfort V9.0 or later.

This helps customers protect existing engineering work and transfer proven application logic to the new LOGO! generation without starting from scratch.

Customers should clearly distinguish between the software project and the hardware setup. Existing circuit programs can often be transferred, but the hardware configuration must be checked and adapted to LOGO! 9 components where needed. LOGO! 9 hardware is not compatible with previous LOGO! hardware generations.

Before migrating an application, customers should review the existing circuit program, the required I/O, voltage class, display concept and available LOGO! 9 components.

LOGO! Soft Comfort V9 is available as a license for use on one workstation and can be ordered via the Siemens Industry Mall. With a valid license, customers can use the full software scope for engineering, simulation, online testing, documentation and commissioning of LOGO! applications — including LOGO! 9 and previous LOGO! generations.

For LOGO! 9, LOGO! Soft Comfort V9.0 or later is required. The software supports LOGO! 9 Basic Modules, LOGO! TDE and the new LOGO! 9 device types. Existing LOGO! projects from previous generations remain usable and can be converted, helping customers move to LOGO! 9 while protecting their existing engineering work.

Existing LOGO! Soft Comfort users can use the available upgrade download via Siemens Industry Online Support to move to LOGO! Soft Comfort V9. This makes it easy to continue working with existing projects in the latest software version.

A free demo version of LOGO! Soft Comfort V9 is also available via Siemens Industry Online Support. It allows customers to get familiar with the software, create and simulate LOGO! programs, test the engineering workflow and explore the main functions before purchasing. The demo version supports offline engineering and simulation; program transfer to a real LOGO! device is not enabled. With a valid license, the software can be used without the demo restrictions.

When LOGO! 9 is connected via Ethernet, web server or other network functions, security should be considered from the beginning.

Customers should use strong passwords, protect administrator access and enable only the communication functions that are actually required for the application.

LOGO! 9 includes security functions such as secure LOGO! communication, user management and access control, certificate management and audit log functions. For secure operation, customers should also keep software and device versions up to date.
