13.1.2 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 acvate the network control. In case of acvated keypad control, the
motor can only be started via the network control word. However, the condion is that
switch S1 is closed.
•
If switch S1 is opened again, the motor is stopped (irrespecve of the acve control
source).
