Behavior on Failure of the Supply Voltage
Failure of the load power supply L+ of the diagnostics-capable analog module is
indicated in the case of parameterized two-wire transmitters by the EXTF LED on
the module. Furthermore, this information is made available on the module (entry in
diagnostic buffer).
Triggering of a diagnostic interrupt depends on the parameter assignment (see
Section 5.7).
5.5.2
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 5.16.
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.
