Cause / remedy

Caution!
Device not responding

•

Communication with target device is not

possible

•

Is the device in operation?

•

Is the device connected to the Konnex

bus?

•

Has the device address been changed?

Datapoint shows a value that does
not make sense (e.g. room tempera-
ture 655.3 °C)

The device does not support information
describing what is visible; datapoint has no
meaning in the current configuration

Setting does not produce any effect

The device does not support information
describing what is visible; datapoint has no
meaning in the current configuration

3.7 User-defined

text

User-defined text from the devices is adopted, which means that the display on the bus
operator unit is identical with that on the local operator unit (RMZ790 / RMZ791). The
bus operator unit reads the user-defined text from the respective device. The RMZ792
displays the default text until the text from the device is received.
