A normal controller installation uses different operator’s interfaces. A division into two main
categories can be seen with respect to their applications:
• Operator’s interface for process control.
– Operator stations
– Mimic panels
–Printer.
• “User interface” for the controller seen as a computer resource.
– System maintenance.
These different facilities are presented in the product overview description, see Section 1.7.9,
Operator’s Interface.
The “user interface” application is described in detail in Chapter 4, Runtime Operation and in
Chapter 5, Maintenance.
