Wire-Break Check
The wire-break check is available for the 1 to 5 V voltage range and the 4 to 20 mA
current range.
The following applies to both measuring ranges:
Enabled wire-break check, the analog input module enters a wire-break in the
diagnosis if a current falls below 3.6 mA (0.9 V).
If you have enabled diagnostic interrupts during configuration, the module
additionally triggers a diagnostic interrupt.
If no diagnostic interrupt has been enabled, the illuminated SF LED is the only
indication of the wire-break and you must evaluate the diagnostic bytes in the user
program.
With a disabled wire-break check and enabled diagnostic interrupt, the module
triggers a diagnostic interrupt when the underflow is reached.
