9.3.8

Current loop (3.8)

9.3.8.1

Loop test (3.8.1)

Provides step-by-step procedure to simulate the loop current.
A loop test can be initiated via local operation (with any errors reported through diagnostic icons
on the local display), or remotely, using an engineering system such as SIMATIC PDM.
Note
Simulated current output
The simulated current output value influences output to the control system.
A simulated value can be set to test the functioning of the mA connections during
commissioning or maintenance of the device.
Setting
Default
Select a preset mA value, or enter a custom value (under option "User") to run the wizard.
Press
For more information, see mA control (Page 86).

Terminal voltage (3.8.2)

Displays the voltage present at the device terminals.
9.3.9

Resets (3.9)

9.3.9.1

Device restart (3.9.1)

Used to restart device without disconnecting power.
Simulation will be terminated. Stored configurations are not reset.
