Info
Simulation of an output current
This menu appears once for each current output.
If you simulate the value at the current output, this is
indicated on the display by a simulation icon in front of
the current value.
Set the desired simulation value.
Simulation of a relay state
This menu appears once for each relay.
If you simulate the relay state, this is indicated on the
display by a simulation icon in front of the relay display.
Set the desired state.
The relay switches in accordance with your setting when
you switch on the simulation. The display shows "On"
(="Low") or "Off" (="High") for the simulated relay state.
Simulation of a measured value (only for sensors)
This menu appears once for each measuring input.
If you simulate the measured value, this is indicated on
the display by a simulation icon in front of the measured
value.
Set the desired simulation value.
If you simulate the temperature measured value, this is
indicated on the display by a simulation icon in front of
the temperature.
