Example 2: Change-over from terminal control to network control

14.1.2 Example 2: Change-over from terminal control to network control
The control is executed primarily via the I/O terminals: Switch S1 serves to start and stop
•
the motor.
Switch S2 serves to activate the network control. In case of activated keypad control, the
•
motor can only be started via the network control word. However, the condition is that
switch S1 is closed.
If switch S1 is opened again, the motor is stopped (irrespective of the active control
•
source).
