System functions
Access rights
Access rights can be used to lter information from the plant and system based on the individual requirements of a user. The caretaker or
service engineer, for example, only has access to information important to him. A distinction can also be made between read access and
write access.
Freely-denable access rights
Only authorized personnel are granted access to the system via the operator units. When a user enters a user name and password, the
system veries the associated access rights and enables access to the relevant plant. Read and write access rights can be dened in
detail, right down to individual information points.
The following access classes are supported in the Desigo system:
• Internal, service and standard service
• Administration and experts
• Standard and customer
Efcient plant overview
For simple and efcient plant overview, the Desigo touch panels PXM40/PXM50 can display the most important plant values on an
overview page, even without logging on.
