Simulation Switch Output (OU1)
Navigation Diagnosis → Simulation Switch Output (OU1)
Description The simulation affects the process data only. It does not affect the physical switch output.
If a simulation is active, a warning to this effect is displayed so that it is obvious to the user
that the device is in the simulation mode. A warning is communicated via IO-Link (C485 -
simulation active). The simulation must be ended actively via the menu. If the device is
disconnected from the power supply during the simulation and power is then resupplied,
the simulation mode is not resumed, and instead the device continues operation in the
measuring mode.
