Behavior on failure of the supply voltage
Failure of the supply voltage of the analog modules is always indicated by the SF
LED on the module. Furthermore, this information is made available on the module
(entry in diagnostic buffer).
Triggering of the diagnostic interrupt depends on the parameter assignment (see
Section 4.7).
4.5.2 Effect of Range of Values of the Analog Values
Effect of errors on analog modules with diagnostics capability
Any errors that occur can lead to a diagnostics entry and a diagnostic interrupt with
analog modules with diagnostics capability and corresponding parameter
assignment. You will find the errors that might be involved in Section 4.16.
Effect of range of values on the analog input module
The behavior of the analog modules depends on where the input values lie within
the range of values.
