Performance Characteristics Of The Automation Systems, As Of - Siemens SIMATIC S7-400 Configuration And Use Manual

Special Applications
The following SIMATIC S7-400 versions are available for special applications:
• S7-400F, with CPU 416-2F for fail-safe applications.
• The fault-tolerant S7-400H, with CPUs 414-4H and 417-4H for fail-safe
applications. As the S7-400HF, this can also be used for fault-tolerant
applications.
• WinAC Slot, S7-400 CPUs as PC plug-in cards for PC-based applications.
