Comparison Of System Configurations With Standard And Fault-Tolerant Communication - Siemens CPU 410-5H Process Automation System Manual

Characteristic values of redundant automation systems
A.2 Comparison of MTBF for selected configurations
A.2.3 Comparison of system configurations with standard and fault-tolerant
communication
The next section shows a comparison between standard and fault-tolerant communication
for a configuration consisting of a fault-tolerant system, a fault-tolerant CPU operating in
stand-alone mode, and a single-channel OS.
The comparison only took account of the CP and cable communication components.
