Operation concept
The operation concept makes a distinction between the following 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 extends beyond value read-off
tasks, the tasks involve 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.
Service engineer/
technician
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 product life cycle, but their
device requirements are often extremely high. 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.
