Generation of a safe temperature value through redundant reading of non-safe temperature values
https://support.industry.siemens.com/cs/document/109812701/generation-of-a-safe-temperature-value-through-redundant-reading-of-non-safe-temperature-values
In the application example "Formation of a safer temperature value by redundant reading of non-safe temperature values", two thermocouples are read in at two ET 200SP standard analog inputs and plausibility is checked in the fail-safe program.
In this example, fail-safe temperature detection up to SIL2 according to IEC 62061 and PLd according to EN ISO 13849-1 is implemented.

Two thermocouples are read in at two ET 200SP standard analog inputs and plausibility is checked in the fail-safe program.

Typical application scenarios for this are:
Monitoring for exceeding or falling below a limit temperature
Release of process steps only within a certain temperature range (maintenance/maintenance)
Tool-dependent temperature monitoring for production steps
Safe monitoring of a heating element
The advantage of this example is the simple integration into an existing system consisting of fail-safe SIMATIC S7 PLC and SIMATIC ET 200SP in the TIA Safety Advanced environment.
