Hello Sunny; Maybe the information in this manual can help explain why it is not possible to obtain a TÜV certificate for any S7 CPU SIMATIC Industrial Software S7 F/FH Systems - Configuring and Programming 1.1 Overview S7 F/FH Systems fail-safe systems The fail-safe automation systems ("F-Systems") S7 F/FH Systems are used in systems with stringent safety requirements. The objective of S7 F/FH Systems is to control processes with an immediately achievable safe state. In other words, F-Systems control processes in which an immediate shutdown does not endanger people or the environment. The S7 F Systems optional package comprises the following two components: ● S7 F Configuration Pack V5.5 SP6 ● S7 F Systems V6.1 Achievable safety requirements With S7 F/FH Systems, you achieve the following safety requirements: ● Safety Integrity Level SIL1 to SIL3 in accordance with IEC 61508 ● Category 1 to 4 in accordance with EN 954-1 … Hardware components The hardware components of S7 F/FH Systems include the following: ● F-CPU (CPU 412-3H, CPU 414-4H, or CPU 417-4H) ● Fail-safe inputs and outputs (F-I/O), such as: – S7-300 fail-safe signal modules in ET 200M (distributed configuration) – Fail-safe power and electronic modules in ET 200S – ET 200eco fail-safe I/O module – ET 200pro fail-safe modules – Fail-safe DP standard slaves – Fail-safe PA field devices |
