* = With configuration via PROFIBUS GSD file, the two short-circuit diagnostics ("Diagnostics: Actuator
supply short circuit to ground" and "Diagnostics: Short circuit to ground" for voltage outputs) are
activated or deactivated using a module-wide parameter “Diagnostics: Short circuit to ground".
They cannot be adjusted independently of one another.
Short-circuit detection
The diagnostics for short circuit to ground can be configured for the voltage output type.
Short-circuit detection cannot be guaranteed for small output values (between 0.1 V and
+0.1 V).
Wire break detection
The diagnostics for wire break can be configured for the current output type. Wire break
detection cannot be guaranteed for small output values (between -0.2 mA and +0.2 mA).
