To ensure trouble-free functioning of the bus operator unit, compatible software versions
of the different types of communicating units must be combined. For compatible units and
versions, refer to document J3100 (Synco™ 200 / Synco™ 700 Valid Version Set).
3.2
Remote operation and local operation
The bus operator unit provides access to the datapoints of the bus users’ user
and service levels. But the datapoints of the bus users’ password level are to be
accessed via the local RMZ790 and RMZ791 operator units. For this reason, the
RMZ792 bus operator unit cannot be used for configuring and commissioning
plant.
3.3
Navigating on the device list
During commissioning, the device list (list containing all bus users) is generated. Data-
points are always to be accessed via the device list – with the exception of the favorite
pages (refer to section 3.4 “Quick access with favorites”). By selecting the required unit
from the device list, the operator reaches the menu tree of the unit needed.
Menu tree and navigation are not any different from local operation with the
RMZ790 or RMZ791.
When pressing the INFO button during navigation, the following information is displayed:
