7.2 Operating concept
Operation with an operating menu is based on an operation concept with "user roles" .
User role Meaning
Operator Operators are responsible for the devices during normal "operation". This is usually limited to
reading process values either directly at the device or in a control room. If the work with the
devices goes beyond reading, it concerns simple, application-specific functions that are used in
operation. Should an error occur, these users simple forward the information on the errors but
do not intervene themselves.
Maintenance Service engineers usually work with the devices in the phases following device commissioning.
They are primarily involved in maintenance and troubleshooting activities for which simple
settings have to be made at the device. Technicians work with the devices over the entire life
cycle of the product. Thus, commissioning and advanced settings and configurations are some of
the tasks they have to carry out.
Expert Experts work with the devices over the entire life cycle of the device, but, in part, have high
requirements on the devices. Individual parameters/functions from the overall functionality of
the devices are required for this purpose time and again. In addition to technical, process-
oriented tasks, experts can also perform administrative tasks (e.g. user administration). "Experts"
can avail of the entire parameter set.
7.3 Structure of the operating menu
User role Submenu Meaning/use
Operator Display/
operat.
Contains parameters that are needed to configure the measured value display
(selecting the values displayed, display format, etc.). With this submenu, users can
change the measured value display without affecting the actual measurement.
Maintenance setup Contains all the parameters that are needed to commission measuring operations.
This submenu has the following structure:
• Standard setup parameters
A wide range of parameters, which can be used to configure a typical application,
is available at the start. The measuring mode selected determines which
parameters are available. After making settings for all these parameters, the
measuring operation should be completely configured in the majority of cases.
• "Extended setup" submenu
The "Extended setup" submenu contains additional parameters for more in-depth
configuration of the measurement operation, for conversion of the measured
value and for scaling the output signal. This menu is split into additional
submenus depending on the measuring mode selected.
