Fault Diagnostics

5.2
Purpose of diagnosis
Diagnostics are used to determine whether fail-safe module signal acquisition is taking place
without errors. Diagnostic information is assigned either to one channel or to the entire F-
module.
Diagnostic Functions Are Not Critical to Safety
Diagnostic functions (displays and messages) are not critical to safety and therefore are not
designed to be safety-related functions. That is, they are not tested internally.
Diagnostic Options for Fail-Safe Modules in ET 200S
The following diagnostic options are available for fail-safe modules:
• LED display on the module front panel
• Diagnostic functions of F-modules (slave diagnostics in accordance with PROFIBUS
Diagnostic Functions That Cannot Be Activated by the User
Fail-safe electronic and power modules provide diagnostic functions that cannot be assigned
as parameters. This means that diagnostics are always activated and are automatically
made available by the F-module in
fault.
