SIMATIC S7 F Systems V6.4 is the primary programming package for creating safety-oriented user programs in SIMATIC S7 CFC, supporting safety levels up to SIL 3. This version allows these safety programs to run on S7-400H CPUs in singular, single-channel, or fault-tolerant redundant configurations. Key Updates & Version Information
The software has received several updates since its initial release:
V6.4 Update 1: Primarily addressed an issue in the F_CH_AI channel driver where simulation values now take priority during channel errors. It also fixed inconsistent configurations for specific ET 200SP HA HART modules during redundancy or movement.
V6.4 Service Pack 1 (SP1): Released in late 2024, this pack added support for newer operating systems like Windows 10 LTSC 2021 and Windows Server 2022. It also introduced support for the ET 200SP HA F-DI 16xNAMUR HA module.
S7 F Device Integration Pack V6.4 Upd2: Specifically manages module drivers and PROFIsafe address assignment directly from the engineering system. System Compatibility & Requirements
