Configuring PI services of the NC as system
functions
9.1

Overview

Purpose
In WinCC, you can link events (e.g. "Key pressed") with predefined functions. If an event
should occur during operation, the function triggers a certain action on the HMI device or in
the control.
Principle
In general, you can use the functions for the following:
● Establish the configuration on a process-for-process basis (e.g. branch from one screen
to another).
● Control the process (e.g. set control parameters).
● Carry out the system settings online at the HMI device (e.g. changing interface
parameters).
As a rule, functions and events are linked to a certain object. For example, a function with
event "Press key" is not triggered by every key, but only by one specific key.
Objects, which can be linked to functions, include:
● Function keys and command buttons
● Fields
● Screens
● Tags
The number of functions offered is, therefore, dependent on the HMI device and on the
situation.
